They took on a project that Tesla declined at the last minute and executed it flawlessly. Despite tight constraints, the team completed the installation within a week and passed inspection without a single issue. Sameer is extremely approachable, patient, and thorough in answering questions, which made the whole process stress-free. Highly professional work--I definitely recommend them. read more

Sameer and team are the best. They are very reliable. They completed the solar panel, battery installation and main panel/sub panel upgrades without any hassles. They managed all the permits and inspections very well. Sameer worked together to find solutions when I had main panel constraints. His entire team is very helpful. He has a solid team. read more

SunVault Solar made going solar incredibly easy. I wanted to beat the December 31, 2025 deadline to qualify for the 30% federal rebate, and Sameer (owner/CEO) assured me they'd get everything done in time. Not only did SunVault finish the installation early--they even secured PTO from PG&E before Thanksgiving. Their team was professional, honest, and efficient from the first consultation through the final install. Because SunVault uses its own in‑house crew (no subcontractors), the whole process felt seamless. City permitting was quick and painless since everything was done to code and they're local to Fremont. Thank you Sameer, Krishna, Vishnu and Yogitha! The system looks great and runs flawlessly. If you're in Fremont (even greater Bay Area) and considering solar, SunVault is an outstanding choice. read more

Sameer and team did a great job of installing solar and battery system for our home. They offered a prompt and reasonably priced service. They took the effort to understand and propose a solution for the specific situation of our project that involved a flat foam roof. read more

SunVault was referred to us by our neighbor who had used them for their solar install. We were up against the Federal Tax credit expiration clock; Sameer (CEO) was very upfront about the chances of getting us in his schedule for the remainder of the year and also gave us lease options in case we missed the federal tax credit deadline. It was great that he was able to slot our installation in 2025. Installation process was quick and efficient; the crew led by Vishnu and Krishna was very professional. Sameer himself was present during the city inspection and made sure it went smoothly. I strongly recommend SunVault for your solar project. read more

i started our solar project by searching yelp for installers at or near 5 stars with a good number of reviews, and I narrowed it down to the 4 closest to us and requested a quote. Sameer was the most responsive by far of any installer. Moreover, he spec'd out a more robust system than the others, (18 PV Panels + Tesla Powerwall3 / Gateway / EV charger) and still came in at a lower cost. I signed the contract on 7/25, and the work was complete by 8/22, and that included getting approval from the city and our HOA architectural committee. The work only took about 2 1/2 days, and Sameer took care of all the interactions with the city and PG&E, which made things very easy for me. Our HOA required an inspection from the roofing contractor and no serious issues were found there. The city inspector was very methodical, and his final comment was, "nice work" I strongly recommend that you give SunVault the opportunity to bid on your project! read more

I contracted SunVault to handle my solar + battery install this year. This is on a flat roof (foam), 18 panels + a powerwall 3. Their quote was very competitive compared to others that I received through energysage and by searching reddit/yelp. They were very professional, showed up when they said they would, cleaned up the worksite before they left for the day and delivered what was promised. I actually had a spot on the roof where some crows had pecked a tennis ball size hole in the foam roof last year. The crew just patched it up while they were up there installing the panels without even asking me. Basically they seem like a company that will treat you fairly as they would want to be treated in return and I appreciate this. I did have some trouble with my powerwall being DOA and they handled the powerwall replacement without any work on my part. Overall I would recommend them and would choose them again. read more

Sameer and his team (Vishnu, Krishna, Yogita, and Ivan) were absolutely fantastic! I signed the contract on September 11th, 2025, and the entire installation and inspection process was completed on October 29th, 2025. PG&E granted PTO in about a week, on November 5th, 2025. Sunvault handled the entire process with incredible efficiency and smoothness. On the other hand, I had an approved NEM2 application with another solar company that unfortunately went under. The application was then transferred to two other contractors, but all of them were stuck 6 months each in the process and couldn't take over. Sunvault pulled off the entire transfer, permitting, installation, and inspection in just six weeks! If there's an option for rating Sunvault's performance higher, I would give them more than 5 stars! It's one thing to stick to commitments, but it's another level when it comes to how they handle the challenges that arise during a project. I had a complex roof line that made the installation quite tricky, and the supplier delivered some broken panels. But Sunvault resolved these issues within days, and the inspection went off without a hitch. I wholeheartedly recommend Sunvault for anyone looking to undertake a solar project! read more

We decided to get solar during 2025 to qualify for the Federal tax credit. We got referrals from a few companies so went for the proposals. Sameer's proposal was the best thought out and comprehensive with a competitive price, and he clearly answered all of my many questions. And it's great directly dealing with the CEO rather than someone in a call center like with larger companies. The original plan was to do this project in November, but Sameer pulled in the schedule to September. Showed up and completed the project on time. He and his team also handled all the paperwork with the city and PG&E, which all went smoothly. Now we're enjoying solar cells charging up the battery during the day! Definitely recommend SunVault Solar for solar projects. read more

The installer has been unprofessional and unresponsive: they have not returned calls for the past two weeks and, when contacted about a power issue, only told us over the phone to contact an electrician instead of arranging the necessary fix. read more

Sameer and his team recently installed a large system at our home, including 27 panels, 20kWh of storage, a span EV charger, and 2 span electrical panel upgrades. Throughout the process Sameer was incredibly responsive and clear. Once we had the permits, the team moved at light speed, finishing most of the install within a few days. They also paid close attention to aesthetics that made the entire project not only functional but also good looking and clean. I can't recommend Sameer and his team enough. You'll be in good hands. read more

I was looking for a solar installer in January this year. I have checked on multiple places including getting quotes on Energy Sage. I stumbled upon a reddit post where multiple people were recommending SunVault so I decided to send them an email for a quote. Sameer was very quick to reply to my email and answered all the questions I included in the initial email as well. He was able to give me a very competitive quotes for the 7kwh solar system with 2x batteries (Enphase) ~ $30k. I had a couple more follow up questions and Sameer gave me a call to answer all of them which was great. I was debating whether to replace my roof since I don't know how old it is and doesn't look like the previous owner pulled a permit for replacing it. Sameer gave me an advice based on pictures I took with my roof that it should be fine to go ahead with solar installation. I called a couple roofing contractors to come out to check the condition of my roof and all were pretty inconclusive about the lifetime left - 5 years - 15 years. Given I don't want to replace my solar system in the next 10 - 15 years, I reached out to Sameer to ask for a roofing replacing quote. For my 1500 sqrt ft unit, the quote was $17k, the 2nd lowest of the 5 roofing contractors I reached out to, so I decided to go ahead and replace the roof with them as well. The start date of my installation was delayed by 2 weeks due to some rainy days which probably delayed Sameer's other projects but that's fine to me because you can't really control the weather. One minor inconvenient thing that will need to be taken into consideration is that - given SunVault looks like a small local business, all the logistics are probably not completely hashed out. Example - for the roof replacement, Sameer reached out to me about 3 days before actual installation and we had a day or 2 to pick the color of our shingles. I'm pretty flexible so I didn't mind this so much but it might matter to some. The project went pretty smoothly. All permits and inspections were taken care of by SunVault. Roof replacement was great, took exactly 3 days where the contractors were working from 8am - 5/6PM. Solar was installed a day later and took about a week for complete PGE integration (SunVault did the NEM 3 application for me too). All the contractors were pretty courteous and attempted to clean up after themselves but there are still definitely some nails and debris lying around afterward that I had to do some more clean up - which I guess they did the best they can and some leftovers are unavoidable. Overall, I'm pretty happy with the installation of the roof and solar. Some minor logistic complications here and there but in the grand scheme of things, SunVault team did a great job! read more

Sameer is very responsive and provides every details for the quote and explains technical issues clearly, this is why we went with SunVault. They also provide competitive yet reasonable pricing for our solar + battery installation. The quality of the panel and PowerWall seems decent. The installation went smoothly despite having some issue turning on the system after PG&E connecting the meter. As we're worried about leakage, we asked our roof contractor to do an inspection after installation and they seem to be OK with the installation quality, although they did not go in our attic to check everything. Will update after the rain season and I hope we don't run into any issue. read more

I had a fantastic experience with Sameer and his team. I was comparing prices for solar companies before the NEM 2.0 deadline, and SunVault was very competitive on price. In June 2023, SunVault completed installation of a 11.2kW system consisting of 28 x 400W Q.Peak panels and Enphase IQ8+ inverters. They also include the Enphase consumption monitors (allowing you to see how much power your house is using) as part of their quote -- some installers charge extra for this. As someone new to solar, they did a great job explaining everything and walking me through the process. The system easily passed city inspection. The left side of my roof faces south-east and has a lot of protrusions from plumbing vents, a sun tunnel, and a vent from the hot water system. Two other companies told me they couldn't install panels in this section at all due to the spacing of all the protrusions. SunVault managed to do it and it turned out great. They ran the conduit on the roof rather than in the attic, which is fine for me since my house is two-story and you don't actually see any of the panels from the ground. I had an issue with incorrect consumption data in Enphase's system. SunVault went above and beyond to contact Enphase about it, escalate it to higher ups at the company (when the low-level techs said they couldn't see any issues), and kept contacting them for status updates until the issue was resolved. I really appreciate the amount of effort SunVault put in to ensure my system was operating properly. Enphase's hardware is great but their support is pretty bad. If you're looking for a solar installer that really cares about their work, I'd definitely recommend SunVault. read more

SunVault Solar - Solar Installation Near Me - Cupertino, California

I don't write yelp reviews unless something amazing or terrible happens - in this case, the service was quite amazing. I was helping my parents through solar as they needed a reroof and was looking for the most reliable installers with the best panels and storage. I reached out to 14 companies (local and regional) and got over 20 quotes including self-installation options. Of these companies, only Sunvault and Sameer along with 3 other companies were willing to coordinate with our own chosen roofers. Of those companies, only Sunvault and one other company were willing to offer top-of-the-line panels and warranty (REC Protrust Certified) with installation, at the lowest costs compared to the rest of the companies and even self-service installation! We installed a Tesla Powerwall 3 with a Meter Collar and DC-connected 18 REC Panels for an 8kW system in San Francisco. When you reach out to Sunvault, you directly contact the owner Sameer. Sameer is super responsive and will be in touch throughout your whole project. This was especially helpful when coordinating with our roofers. He was very accommodating of scheduling changes as needed and has been very communicative and reachable for any questions and concerns after the installation. His team completed our project in 2 days and took care of all the permitting with the city, PG&E, scheduling, and being on-site with you for DBI and Fire inspectors. This was all finished in less than a month. The inspectors were super quick and impressed with how ready Sameer was with documentation and thoroughness. Their team made this process pain-free. I recommend Sameer and his team at Sunvault Solar to anyone in need of a solar project, and would happily choose them again for any future projects. read more

Sameer and his team are really good. From quote to install, to making it operational and then answering my questions at all stages, they showed their best side and made the whole process easy for us. From quote to being operational, it hardly took them 6 weeks. Clean and efficient job and made sure they get the inspection done right as well. Thank you! read more

Very happy with the experience of having SunVault solar install a rooftop solar system with batteries. Their quote was competitive, the owner is very responsive, and the whole process was easy, smooth, and quick. From installation to having the approval to getting PTO, it took only a few weeks. The installation job was very well done, they even painted the conduits to match the home color. Highly recommend this company! read more

DO NOT USE THIS COMPANY!!! After they completed the roof we had another roofing expert examine it and he said it was one of the worst jobs they had ever seen. It was so bad, there were too many issues to fix so we are having another company completely redo the roof. Sunvault is refusing to respond now and we are initiating legal proceedings to hold them accountable for the horrible work they completed. Longer version: We needed to redo the roof on our house and replace an older solar system. We looked at several options and landed on Sunvault due to their good Yelp reviews and their price to complete both of these jobs came in a bit lower than others. Initially communication with Sameer (the owner) was good. They started with the roof tear off and put down some underlayment paper. There was rain coming that night so I confirmed with Sameer that everything was watertight. As the rain started, we had multiple gallons of water pouring through the ceiling of one room and large leaks around skylights in two other rooms. The next morning I went up on the roof and discovered a whole flat section of the roof was totally uncovered. We found out later just the underlayment they had on the roof is insufficient for waterproofing while the job is in progress. Sameer promised this was a totally isolated incident and not an indication of the quality of work. He promised "changes would be made" but the exact same crew continued working on the roof. Since more rain was coming we didn't have an option to switch to another roofer so we let them continue which turned out to be a major mistake. Sameer took responsibility for repairing the damage inside of the house caused by the leaks. It took close to a week for them to complete the demo of the drywall. We had a mold test done and it came back positive for dangerous mold due to the slowness of removing the wet plaster and drywall. Sameer found a drywall crew to repair the drywall which took close to a month and was very disruptive to our living environment. All of this was totally avoidable with some simple waterproofing. As the roof job continued I noticed several mistakes and general sloppiness. The roof vents were so misaligned I could see daylight through them in the attic. They forgot the take the sticker off a skylight and they were not well aligned in the openings. There was water pooling in one corner of the roof. The slope of the shingles flattened toward the edges but they didn't install a waterproof membrane underneath. I continued to bring up these issues and they would do the minimum they could to fix it. It was clear they just didn't care. I felt like I had to watch them like a hawk to ensure they weren't making careless mistakes. The solar install went mostly smoothly but there were a few small issues such as lack of labeling and incorrect breakers that were found at inspection time. As the roof was completed, I had a bad feeling that there were other mistakes I couldn't see. A few months later I had a roofing expert come inspect the roof. He was absolutely shocked at the quality of the job, calling it as bad of a job as he had ever seen. He was amazed it was done by professional roofers and looked more like handymen just winging it. He said "roofing isn't that complicated but they somehow did almost everything wrong". He listed a litany of errors that were perversive to the whole job. For example, there were flashings around the skylights that were not even attached. There were so many problems that going in and fixing them would take about as much work as just replacing the roof. There also may be other problems that were not visible that would someday cause a leak. The only way to have peace of mind would be to replace the whole roof so this is what we will be doing. I contacted Sameer with all of this asking them to take responsibility for this terrible work. He has refused to respond to repeated emails and texts. We have been left with no choice but to initiate legal proceeding to try to recover some of these costs. I learned during this process that Sunvault is just a side hustle for Sameer. He has a full time job at Meta working in finance. He is not a roofing expert and has learned solar on the side. It's clear he just hires cheap labor to complete the job with no supervision and he lacks the knowledge to even recognize how bad the roofing work is. I urge you to learn from my awful experience and stay far away from Sunvault! read more

SunVault Solar - Leak around skylight caused by lack of waterproofing during reroofing - Solar Installation Near Me - Cupertino, California

Highly recommended! Just completed a 10KW system (25) panel install and easily passed inspection in Los Altos. Sameer really cares about the quality, at one point he noticed the panels were not as aligned as well as they could have been and had the crew reinstall all the panels. Looked at bunch of places during the NEM 2.0 rush (April 2023), choose Sunvault based on strong word of mouth recommendations. It's a smaller operation but they moved fast and got the paperwork done to get in under NEM 2.0. They also do new roofs and main panel upgrades. Will be working with them again in the future to add a battery. read more

SunVault Solar - Solar Installation Near Me - Cupertino, California

Sameer and his team is great! The price is very competitive, and the service/produce worth every cent. Sameer is very responsive to my messages and always willing to discuss with me about the solar system design. We changed the design several times, but he kept his original quote. I waited around a month to have the system installed after signing the contract. I'd say it'll be faster if we don't need to wait for the new Powerwall 3. read more

It was pleasure working with SunVault for my Solar installation. My situation was little convoluted and lengthy. As my house was under construction when I decided to get registered within NEM 2.0 timeframe. SunVault were able to handle all these situations for me seamlessly, with zero participation or involvement from my side. My construction went through unexpected delay & inturn with Solar installation. Sunvault is totally accomodative. They were very flexible & completely receptive of individual preferences with Solar panel placements. They are helpful post-installation as well. Guiding me & giving inputs on how to plan if there is increase in power needs. Thank you SunVault & Sameer. read more

Sameer and his team were great to work with - very responsive from start to finish. Initial quoting was thorough and Sameer took the time to answer all my questions. Through the installation Sameer kept me informed and his team was fast when on site. Even as the owner, Sameer was very responsive on text. Additionally, we unfortunately had our controller unit fail within a month; Sameer continued to escalate to enphase on our behalf to get a replacement unit at no cost to us. Very much appreciated having the support of the installer to get service from the equipment manufacturer to fix the warranty issue. Overall great experience and would strongly recommend read more

I worked with Sameer to install Enphase batteries. Super fast, clear, and easy. I continue to recommend Sameer and SunVault!

SunVault team did a good job on installing my solar panels and the battery. Sameer planned everything well. He listened and accommodated requirements, e.g., battery inside or outside. They submitted city/PGE applications and scheduled appointments, made it to be a turn-key solution. I am glad I chose SunVault and would recommend to anyone for your solar needs. read more

This review is one year in the making.....Meaning I went from thinking about installing solar to choosing eight local solar companies (and their products), to compare and contrast their offerings and quotes. I live in Aptos and thought choosing a local company might be best....But the two that I chose, came in with a quote higher than I expected. So I expanded my search to solar companies in/around Santa Clara valley. Glad I did. The average quote of the remaining six companies was $14K less than the two local companies. It was a drawn-out process as I tried to be sure the products were identical or comparable in quality and cost....I finally decided on Sunvault Solar and so glad I did. Sameer was quick to respond via email and answered any question that I had. I ended up going with 16-460 Rec panels and 2-Enphase 5 kw batteries and Sameer's quote was by far the best of the remaining six companies (note: I asked each company if I wanted to add another panel or battery, what would be the cost (per item) and I was surprised that for the same panel, there was over $1k difference per panel or $4k difference for an additional battery). The higher quotes on the extra piece parts actually corresponded with each of the higher quotes that I had received for the entire system from the six finalists. So right there, you could see where their margins were coming from.....The Sunvault Solar installers did a great job and put the system in in two days. The final inspection passed a week later and it's cool to see my electrical useage from PG&E be reduced to almost nothing!!! My recommendation is to ask for quotes from multiple companies, but include Sunvault Solar in your search. You will be glad you did! read more

Fantastic experience with SunVault, very professionals and highly recommended! I started my project with getting recommendations for solar suppliers from friends and neighbors, I contacted several suppliers and got quotes for my project. It was confusing as each supplier suggested something different, totally different size, different configuration and equipment and different price. I decided to do some homework and learned more about solar, what I specifically need for my home, and the current equipment options available in the market. Now I had in mind what I want, and I tried to compare it to the quotes I got; I also asked some suppliers for a new quote for my new specific configuration. It was very clear that SunVault not only suggested the same configuration from the first place but also gave the best pricing for the project. The rest was fast and simple, much easier than I expected. They have a great team that did a great job, I'm very pleased with the process, the installation and the results. Tip - to maximize your solar system, always add a battery or two. It will help you to avoid power outages (surprisingly, solar system needs external power to work) and it will also use the stored power during the night, helping you to reduce/eliminate your bill and grid dependency. read more

I think Sameer is a true solar professional and honest. My experience has been super smooth. I've had Sameer and his team install solar with battery pack. They're also installing an EV charger. I think this is a great team and I'd hire them again for my other properties. I highly recommend SunVault. read more

we've lived in the bay area 40 years. we bought a new construction home in 1999 and lived in it 26 years. pg&e utility rates significantly increased annually. we knew pg&e would accelerate billing rate increases. we planned buying a new home for 2 years. a key component was leveraging the power of powerwall + solar to achieve energy self sufficiency. we spent several years reviewing technology including trips to nevada to review homes completely energy self sufficient. after 18 months searching we found a near perfect new construction home in emerald hills. it had: very efficient electric hvac (carrier/bryant central minisplit) and rheem heat pump water heaters, large roof area amenable to solar panels, unobstructed sun exposure, and the minimum 10 solar panels for new construction. we bought the home in nov 25 and were up against the 31 dec 25 to receive the federal solar tax credit. i had proactively contacted about 10 local solar companies. they all were unresponsive, including tesla, and demanded at least 2-3 actual pg&e bills. i knew from the nevada builders it was possible to calculate the approximate powerwall+solar requirements based on the hvac, water heater, and other significant electricity consumers in the house plus the house size and integrity. sameer at sunvault was the only vendor with the capability and willingness to help plan the system based on the house components and characteristics. he started sunvault because of a similar frustration with solar providers. sameer was incredibly responsive and worked with us to quickly design and buy the system. i'm a veteran of 30 years of bay area data startups. my wife is a former software engineer. working with smart capable people is the key. sameer is a former facebook executive. his knowledge of solar systems (batteries and solar) is unparalleled. he brings the silicon valley mindset of working fast and effective. we decided on 36 460 watt rec alpha series panels and 3 powerwall 3 batteries (1 is an expansion pack). sameer's team installed the system in late december. we replaced the original 10 solar panels installed to meet ca new construction requirements. they worked with us to adjust components to match the house aesthetics. the rec black panels blend in well with the roof and the powerwalls fit perfectly on the garage exterior wall. sameer personally spent a lot of time on site and handled all the inspections (woodside fire and san mateo). the woodside fire inspector inspects solar systems fulltime. he noted the quality of sunvault's installation was impeccable, one of the best he's encountered. he indicated many systems fail first inspection. the system went live about a week ago. it performed perfectly. pg&e showed we were using 45 kwh/day. we're generating 60 kwh day during the winter. we have significant electricity surplus which we planned so we can charge ev's and more liberally run heat and ac. for the first time in my life we're running heat at 70 degree for the entire 4400 sq ft home with plenty of surplus electricity. we look forward to aggressive ac use this summer. over 2 years we met with dozens of builders and solar/battery installers. sameer is head and shoulders superior to all of these in system knowledge, customer orientation, can do spirit, and is just wicked smart. it was nirvana working with another fellow kindred spirit truly manifesting the silicon valley credo. sunvault is by far the best solar+battery system company in the bay area. read more

Sameer and his team were amazing. We got a 6.15 kW system with 3 enphase 5p batteries (15 kWh). From the get go, I got detailed communication from Sameer. No pushy sales tactics - just direct thorough quick communication. Sameer answered a lot of questions I had, unlike any other solar contractor I contacted. I got over 12 quotes total. Sameer's quote was the best which obviously helps but what made me choose him over everybody else was how much time he spent with me even before I had decided to go with them - it was technical discussion (because I like to know the details of the system and what I am getting into in detail). I learned a lot from him and not once did he try to push the sale. Once I signed the contract, within a week he submitted the drawings and the permit application as he had promised. Permitting process took a while but that was just the processing time at the city and once that was done Sameer was in touch with me via texts about the install. The electrician did all the electrical and battery work on the first day and then two additional guys came the next day for the solar panel install. Everything was hooked up and done in two days - again as promised. The install was clean - they knew what they were doing. I had extra exterior paint and they even painted all the conduit they installed so it all blends in with my exterior wall. Vishnu, their engineer oversaw the install, answered questions, commissioned the install, and was present during city and fire department inspections. They take care of everything and they do it well. I have been glued to the enphase app looking at the great production we are getting. We are at less than 3-5% grid dependence each day - it's terrific to see, basically self sufficient and enough to export still. I highly recommend Sunvault solar for your solar install. Please reach out to them even if you have other quotes - you won't be disappointed. read more

We just completed a 19 panel install at our house with SunVault. Sameer was amazing in orchestrating our project: from planning to design, to working with PG&E to ensure we had our ducks in a row before the end of NEM 2 deadline, checking in with regular communication every step of the way, answering lots of questions, and even accommodating my panel placement requests on the day of install. They are professional, organized, and on top of it, even while juggling many concurrent projects during the NEM 2 / NEM 3 switchover period. Even in a NEM 3 world, Sameer and SunVault will set you up for success. We are now generating a healthy surplus of power now which easily supports 2 electric vehicles, electric HVAC, and electric appliances. Total price was competitive, and our project ROI is healthy. Highly recommended. read more

We had an excellent experience with Sunvault (Sameer and team) installing a 8.1 KW system. As a part of a big remodel we were looking to add Solar. While the actual install would happen in 2024 we wanted to get an accurate application in before the NEM 2.0 deadline passed. We got a few quotes from different vendors, not only was Sunvault's quote best but I was very impressed by their openness and responsiveness. Sameer helped us size the system using just the architects drawings and get the application submitted in time. He was very responsive and I did not experience any pushy sales tactics. In fact due to his inputs I dropped the idea of adding batteries right now (a decision I am glad I made). Once our roofing guys were done installing the roof I pinged Sameer and his team was prompt in coming in and installing the system. The install was clean, their team took care of everything. It took us a couple of months after the install to get internet in the house. His team was prompt in coming in and setting that up. Overall we are very happy with Sunvault and would highly recommend them to anyone looking to add solar to their house. read more

Before selecting SunVault, we surveyed multiple installers, from the internet, locals, and big ones such as Sunrun, SunPower. We ended up with SunVault because of the value, pricing, flexibility, locality, support and communication leading to our informed decision. It has been a great experience for us working with SunVault Solar, Sameer and team. Most of all, they took care of everything, including design, permit, install, PG&E application and follow-up, include replacing tiles. They explained the process before starting, report their progress, and worked out schedule with us. The whole process from signing-up to working solar system took about a month, including city permit and approval. The solar system is 8.14 kW, from 22 pieces of 370W LG black panels. We expect to have over 10K kWh yearly production from the system. The solar system include: * 22x LG370N1K-A6 (370W Neon2 black panel) * 22x Enphase IQ7+ Microinverters * Ironridge roof mount/rails * Enphase Combiner box and Rapid Shutdown box Now our Enphase App is showing 30~40 kWh daily production (between cloudy and sunny day) in the first week of October, 2021. We are happy customer and highly recommend this solar installer. read more

I usually don't write Yelp reviews but I decided to take some time out to write a review for Sunvault Solar. With rising PGE bills every month, we finally decided we get solar installed on our property. While chatting with our neighbors (who also went with Sunvault), I got Sameer's reference. Sameer is the owner of the company and does not have a sales team, so once you reach out you would be chatting with him from start to finish. Almost all the projects that he does are through referrals/word of mouth. Sameer is extremely proactive with his responses and very knowledgeable about solar and this industry. As a consumer, you should definitely do your due diligence and reach out to multiple vendors to get different quotes (which I did), but Sameer was the only one who was very prompt and quick to respond back. I do have some shading on my roof and one of the vendors refused to even provide me with a quote, stating that they will not work with us due to the shading! Sameer was quick to get some details from us, PGE data for the last one year and gave us an estimate with ROI and system size to meet our demands. After getting some similar estimates from other vendors, I decided to move forward with Sameer, as his pricing was the most competitive. Sameer's team is extremely professional and diligent. They were super efficient and the installation was done in less than 2 days! One of my main criteria for this installation was that I wanted to get it done by the end of July, since I was heading out of the country on vacation. While other vendors couldn't guarantee that timeline, Sameer promised and ensured that the timeline was met! Below is the timeline of my project: First contact with Sameer: 5/22/2024 Estimate/Quote Received: 5/24/2024 Contract Signed: 6/24/2024 (Took a month to get quotes from other vendors) Permit Received from the City: 7/16/2024 Installation Start/Finish: 7/17/2024 - 7/18/2024 City Inspection Completed On: 7/23/2024 The whole process took less than a month from signing the contract to the city inspection and getting the green light to operate the system! I am extremely pleased with the professionalism, sincerity and commitment shown by Sameer and his team! I will be highly recommending them to all my friends and family members who are interested in going solar! read more

After getting quotes from over 7 solar companies ranging from local installers to national companies, we decided to go with Sunvault for our 6.4 kW solar system installation in San Jose. Working directly with Sameer was a breeze! Here are some of the highlights that make Sunvault stand out from other installers: - Very quick turnaround times - just weeks from signing the contract to installation & PTO. Probably faster than any other solar company in the Bay Area right now, and crucial for getting in before NEM 3.0 hits this April! - Sameer is both the main POC for customers and the owner of the company. At other companies, you talk to a salesperson to get set up and then are often left to fend for yourself. But with Sunvault, Sameer oversees planning, installation, and permitting, and is super knowledgeable about all of these processes so you truly get a custom installation. - Work quality is top notch and all the installers are super friendly. - Sunvault only uses the top quality products (Enphase microinverters, QCell panels, and Iron Ridge low profile racking system) which is often a sign of installer quality. - Super competitive pricing - About a month after getting PTO, and system is up and running perfectly! Our installation was even more complex, with Sunvault handling an electrical panel upgrade to 200A, a complete roof replacement, and then the final solar system installation. All three turned out great: - The electrical panel upgrade was completed in one day and the electrician took great pride in his work and was super friendly when showing me the completed product afterwards. All of the wiring and installation was very neat and organized. - Roof replacement was completed over a couple of days and looks GREAT. There has been SEVERE rainfall and high winds in the Bay Area over the last month and I have had 0 issues. Sameer also uses the highest quality components here (Landmark Pro Solaris shingles, ice & water shield) which gave me more confidence. They were also able to install a couple of bathroom exhaust vents as well as O'hagin roof vents for me which was great! Overall, the entire process was very smooth, especially considering the fact that we had 3 major projects done within just a few weeks. Sameer coordinated everything and permits passed with no issues. He was also super patient - I had many requests and questions and they were all answered and accommodated with grace. Would highly recommend contacting Sunvault for a proposal (do it asap as this company is quickly growing in popularity)! read more

Sameer is so good!!!!!! He is very responsive and willing to help. He is the professional. We had a horrible experience with another solar company name citadel in Vacaville and Sameer helps us right away. We have very good experience with Sameer and are so happy to have him help us in the future. We are very lucky to find him. read more

Just wanted to shout out to Sameer who did my solar installation. He was super easy to chat with and didn't make things overly complicated. Whenever I had a random question or was just curious about something, he was there, ready to help, whether I texted or called him. He laid out everything for me in a way that was easy to understand, and it felt like I was talking to a friend rather than a business owner. It was a great customer experience, thanks to him. If you're even just thinking about going solar, I'd totally recommend hitting up Sameer. He knows his stuff, won't leave you hanging, and is just super chill to work with! read more

We had a great experience working with Sunvault for our solar installation, and would highly recommend Sameer and his team to anyone. If you're thinking about going solar, you need to move _fast_. That's because how net-metering works is about to change significantly -- and unfavorably -- very soon in California. When you have solar, you overproduce electricity during the day when the sun is shining, and send energy into the grid in exchange for credit. Then, when you need more energy than you can produce -- at night, on rainy days, etc. -- you draw energy from the grid, using up your credit. The current rules -- "NEM 2.0" -- say that the energy you export to the grid is worth as much as the energy you import, which means you essentially use the grid as your giant battery -- you store energy there when you have extra, and draw energy when you need it, for basically no cost! Under these rules, there's really no reason to own additional batteries yourself, unless you really care about energy independence. These rules are very (too?) favorable for solar owners. But the rules are about to change. Under "NEM 3.0", the credit for energy you export will be worth much lower than the energy you import, so it will be much harder for your exports to cover your imports without also having your own battery. The new rules will also impose significant fixed cost just for _owning_ a solar system, regardless of whether you are a net exporter or importer. This makes residential solar much less desirable, and pushes the payback period from 5-6 years to 12-15 years. I do think NEM 2.0 is too favorable for solar owners, but NEM 3.0 will pretty much kill any incentives to go solar. The good news is that if you are already on NEM 2.0, then you will be grandfathered for 15-20 years, even after NEM 3.0 goes into effect. The bad news is, while no one is sure when NEM 3.0 will go into effect or what its final form will take, it is expected to happen some time in early 2023. So, the race is on and the clock is ticking! If you want solar, you need to get it installed and operational before NEM 3.0 goes into effect, so you can be grandfathered in with NEM 2.0! I looked into many options when choosing installers. The national players like Tesla Solar tend to have the lowest quotes by far. But they also have very bad customer service (just read the reviews and horror stories), and they're often booked many months out. When I inquired in July, they said they wouldn't be able to get to mine till the end of the year, and that's if things went perfectly smoothly. That's cutting it too close to me; I wanted to be operational ASAP. I got several quotes from local installers, and decided to go with Sameer and SunVault. His quote was very competitive, and he was very knowledgeable and responsive when we talked through my concerns and needs. He's also the owner -- not a salesperson -- so you're dealing with someone who will oversee the entire operation, including showing up at installation and inspection. This gave me more confidence that I wouldn't be left hanging or chasing down the right person. But the best part is -- Sameer's team moved _fast_. My timeline was: 7/27 - contract signed 8/2 - engineering plans designed 8/17 - permit approved (Fremont takes a while!) 8/22 - installation 8/26 - Inspection (passed easily) 9/2 - permission to operate received So, from contract signed to operational only took less than six weeks! This is basically as fast as possible, with most of the time spent waiting for city permitting and inspection. I was amazed! On installation day, the crew was also great. They took good care of my roof and did things the right way. The electrician also took pains to run the conduit as efficiently as possible, even though it took him a lot more time and effort to do so. The outcome looked great and worked great! In the bay area, with ample sunshine and rising electricity rates, it pretty much always makes sense to go solar... if you can get in before NEM 3.0 starts! So if you're interested, you need to move fast now. And if you want to be sure you make it in time, go with SunVault! read more

We had a great experience working with Sunvault Solar, and highly recommend Sunvault Solar. We got quotes from 10+ vendors in the Bay Area, and I am very glad we decided to go with Sameer and his team at Sunvault. I dealt directly with Sameer (the owner) throughout the project. I was exchanging emails with him over the weekend and late into the night while iterating on the panel layout. Once we settled on the layout, he had the final plans sent for permitting in just a couple of days. The install was done by an in-house team, and Sameer was personally present on-site through most of the install. The pricing was comparable to quotes I got on EnergySage, and the equipment and install is top-notch. They installed Consumption CTs (most other installers refuse to do this or charge extra), painted the conduits (I provided the paint), and used black racking and flashing (slightly more expensive, but less conspicuous). The entire process (from signing the contract to PTO) took just four weeks. Other companies I spoke with had a wait time of 12-16 weeks for the install. If you are looking for a high quality install at a reasonable cost before NEM 3 kicks in, I highly recommend giving Sunvault Solar a call. read more
