Our 20-year-old SunPower system experienced an inverter failure (SPR-3200). Most of the advertised SunPower "repair" contractors we contacted seemed more focused on selling a complete system replacement--including roof tear-out and battery backup--rather than offering practical repair options. With our NEM-1 ending in July 2026 and NEM-3 beginning in August, we wanted to explore all viable options. Infinium Solar sales, Jacob Sleep, offered a compatible inverter solution over the phone and the first and only to conduct a thorough on-site inspection of our aging system. Infinium recommended a 5kW inverter (10-year warranty) compatible with our positive-ground SunPower 18-panel array (SPR-220), along with a 15kWh FranklinWH battery (15-year warranty) to prepare for the NEM-3 transition. He also presented an option to upgrade to 12 REC Alpha Pure-RX 460 panels (25-year warranty) but importantly noted that our existing panels appear to be in good condition and could continue performing well beyond their 25-year warranty. That honesty was appreciated. After inspecting our UniRac rails and mounts, Jacob confirmed a full tear-out was unnecessary. He explained that the REC panels could be installed on the existing rails, though a few inches of rail would extend beyond the panel edges. Unlike other contractors, Infinium provided four clear, well-explained options: 1. Replace the failed inverter and upgrade wiring with rapid shutdown devices for the existing panels. 2. Add a 15kWh Franklin battery to the above setup. 3. Install a 15kWh Franklin aPower S hybrid battery/inverter system with required wiring upgrades for the existing panels. 4. Fully modernize the system with a Franklin aPower S hybrid battery/inverter, MAC and meter collar, and 12 REC Alpha Pure-RX 460 panels-- utilizing the existing rails. We chose option 4 to upgrade our solar system with battery back-up. We appreciate Infinium's responsiveness, practical approach, transparency, and willingness to present multiple solutions rather than pushing a full system replacement. Infinium's thorough evaluation and honest recommendations made a complex decision much easier - especially in the absence of the 30% federal tax credit. When we installed our SunPower system 25 years ago the timeline from signed contract to final install was less than 6 weeks including San Jose inspections. We were very dismayed at the current solar system installation timeline. Contract signed June 19th, System operational on September 8th. The Infinium technicians were very adept and efficient - no time wasted. Using the existing conduits, racks, mounts, etc. made the task a lot easier. Stephanie Jacques, the Operations scheduler, advised, guided and followed up with us on the schedule. Everything dealing with the removal, installation and final sign-off seemed to revolve around her. Our timeline was as follows: 06/18/2026 Initial contact with Infinium via phone call/web inquiry 06/18/2026 Same day, sales, Jacob Sleep, inspected our 25-year-old SunPower system 06/19/2026 Contract signed, deposit sent 06/22/2026 Project administrator assigned, conveyed that we wanted the system ASAP 07/07/2026 SunPower system removal - took less than 2.5 hours 07/08/2026 Site survey - photos taken of proposed battery location and current solar layout 07/10/2026 Stucco repaired where inverter, shutoff boxes located. Not great work, had a stucco contractor tidy it up. 07/14/2026 Design phase - 10 days? Existing system! I asked for it to be expedited 07/20/2026 Signed off design 08/12/2026 REC-460 panels installed, overhanging rails cut, PV wiring routed through existing conduit 08/19/2026 FranklinWH aPower S, battery bracket (city) inspection and installation. System is fully installed - PG&E needs to install the meter socket adapter (MSA) - a 10 day window! Also, after PG&E installs the MSA, then the battery comes online and is commissioned by an Infinium tech and final city inspection. 08/28/2026 PG&E installed the MSA 09/08/2026 Inspection scheduled 6-8 weeks ago. FINALLY! We have solar power again! Note: Unfortunately, the city supervisor came out and asked a lot of questions. Dimitri, Infinium battery commissioning guru, patiently answered all the questions. Generally, a 5-10 minute inspection turned into a greater than 30-minute questions and answers session. Bottom Line: Would I use Infinium again? Very likely. The process took longer than expected, but most of that was tied to design, permitting, PG&E, and city inspections. Infinium was the only contractor that seriously discussed repairing our existing system before proposing replacement options. They evaluated what could be reused, what needed to be upgraded, and provided several alternatives with the associated costs and tradeoffs read more

We had a situation where our Enphase stopped working. Due to some changes that we did in garage with dryer. We called Infinium around 5:15 PM and manager Dai who was very gracious and told us that someone will call soon. Then Tavee called us and resolved our issue in few minutes. He was very patient and eyes for details. so through the cell phone pictures he was able to help us. Amazing service with great work. Thank you Tavee. Thank you Amrish for a strong team you have! Will definitely use your service in the future. Thanks read more

# Extremely Disappointing Experience with Infinium Solar -- Poor Communication and Project Management I am a property manager, and I chose Infinium Solar for a newly built ADU solar project. Unfortunately, my experience with them was extremely disappointing. If you value your time and want to avoid unnecessary stress managing your own solar project, I would not recommend using Infinium Solar. ## Initial Experience The sales process was positive. Marcia from sales was responsive, provided different options quickly, and was easy to work with. We chose Infinium Solar because of their good reviews, our positive experience with Marcia, and pricing that was approximately 5% lower than other companies we contacted. Unfortunately, after the project was handed over to project manager Dai Danh, the experience changed significantly. ## Communication Communication became one of the biggest issues. After the initial site visit, there were revisions to the plan, but we had to repeatedly follow up to receive updated plans and pricing. For example, Infinium Solar recommended that our roofer waterproof the mounting anchors to preserve the roof warranty. We needed anchor specifications and quantities to obtain a quote from our roofer, but despite multiple people being copied on the emails, we waited several days for this information. Throughout the project, we constantly had to ask for timelines, status updates, and next steps. Instead of proactive communication, we had to chase Infinium Solar for answers. ## Project Management Issues As a property manager, I understand construction projects are complicated and issues happen. However, the purpose of hiring a professional contractor is to manage those issues. Unfortunately, I felt that I ended up managing the project for Infinium Solar. The clearest example was the roof mounting anchors. Based on Infinium Solar's specifications, my roofer ordered the required anchors. However, Infinium Solar also ordered and installed anchors themselves -- and the anchors they installed were the wrong ones. They eventually asked my roofer to bring the correct anchors for reinstallation. The frustrating part was that my roofer and I had the correct anchors based on Infinium Solar's own specifications, while Infinium Solar did not. The anchor count also changed multiple times (34 50 56), causing additional cost and delays. There was supposed to be a $100/mount deduction because my roofer handled the mounting and waterproofing, but I had to repeatedly follow up before receiving updated pricing. The battery installation was another major issue. The battery location recommended by Infinium Solar was approved by the city but rejected by the fire department during inspection. This required relocating the battery and caused weeks of delay. The relocation also damaged the wall. Infinium Solar initially did not clearly take responsibility for the repair until I informed them my GC would complete the repair and bill them directly. At that point, I had already lost confidence in their work and used my own GC to ensure the repair quality. The timeline was also disappointing. Before signing, we were told there would not be delays after permit approval. However, there was a five-week gap between permit approval and panel installation, even though the installation itself only took one day. ## Billing and Quality Issues The project pricing changed multiple times. While some changes were expected, the anchor-related pricing was poorly managed. Infinium Solar provided incorrect deductions based on outdated anchor quantities, and I had to provide their own previous emails to show the correct count. I also discovered multiple versions of the CAD drawings, and the latest CAD did not reflect the correct anchor quantity. Even after discussing the correct amount with project management, the billing department still sent an incorrect invoice. The installation team also damaged our roof during installation, requiring my roofer to repair the roof membrane afterward. Infinium Solar did pay for the repair, but this should not have happened. ## Lack of Ownership The biggest issue throughout this project was the lack of ownership. After signing the contract, it felt like the level of attention and care significantly decreased. There were repeated examples of internal miscommunication: * Incorrect anchor information * Wrong anchors installed * Incorrect billing * Conflicting instructions from different teams I frequently had to identify problems, coordinate between parties, provide documentation, and push for solutions. A professional contractor should manage the project -- the customer should not have to manage the contractor read more

Great service ! Had a system For 5 years. An inverter went out, they quickly sent me a new one and the next day had a guy come out to install it . They honor there warranties read more

Alvin was very helpful in advising me about updating my PV system, installed in 2020. I needed to deal with my expiring communication with SolarEdge monitoring, and I wanted to check the condition of my back-up battery, because I had received a rather puzzling rebate offer from LG if I returned it to them. Initially he thought I might need a new communication board ($$), and possibly a new battery ($$$), but in the end I learned that fortunately all I had to do was renew my cell plan. Alvin asked me what the warranty was on the battery, which was surprising, given that his company had sold it to me. I had to consult LG to get the answer. Alvin absolutely did his best, but I felt that he had trouble getting the correct answers from his technical team. The entire process could have been handled better by both Infinium and SolarEdge. It took several hours of phone calls and emails to solve what was ultimately a simple problem. But Alvin stayed with me patiently throughout the process, and guided me to the right solution. I think Infinium is trying to improve its customer service. Last spring, when I had my roof replaced, their internal communication was poor, and more than one person contacted me to say they were my project coordinator. read more

Infinium just installed my solar and a powerwall. Professional from start to finish. I will recommend them to my friends!

Excellent materials and great service. I save every day from the sunlight. We are very pleased.

Infinium installed a new hub and batteries for our solar system. The whole process from initial inspection, work proposal to installation was quick, professional, and efficient. Everyone at Infinium was courteous and knowledgeable. I recommend them for your solar needs. read more

I did quite a bit of research before choosing a solar company. I got multiple bids and talked with a number of charismatic individuals. It all started with AT. I think he was the only sales rep I spoke to who arrived in an electric car and actually had solar panels on his own house. He was extremely knowledgeable and had great answers to all my questions. While Infinium was not the least expensive bid I had, I truly believed they were my best option, and I'm happy to say I made the right choice. Everything they quoted happened when they said it would and with no effort on my part. I also need to shout out Alejandro for being the most competent electrician I have ever met. I'm a curious person by nature, and Alejandro answered all of my questions with patience and absolute authority. Once the panels were installed, Alejandro and Rudy (also great) took time to hook everything up. Nothing wash rushed and they did everything the way it was supposed to be done. I waited to post a review because I wanted the final inspection to be done, and I wanted to make sure I could review the entire process, not just the midway point. I should also give a big thanks to Ji, who picked up my calls more than a few times to help me out with things (I probably called to check in too much, but he was always great). There were some very minor issues (I was woken up early because of a scheduling mishap), but Infinium delivered in every meaningful way I could have hoped. Infinium had excellent communication through the entire process (they always picked up the phone), they were consummate professionals through the entire process, and I simply cannot recommend them enough to anyone that will hear me gush about my wonderful experience. Oh, also, the independent research I did confirmed that the panels and batteries they use are the best that money can currently buy. Thank you to everyone at Infinium Solar! read more

I highly recommend infinium solar if you are looking to install solar! Our job was a bit more complicated as it included installing two Tesla batteries, and also trenching to include power at our driveway for an electric vehicle. The layout of our house made it a little bit complicated regarding how to get the power from the Tesla battery over to the main electrical panel. All I can say is that infinium handled all of this with grace. They worked hard to find solutions to all of these issues and difficulties, and they have an amazing supportive team that kept the project moving quickly and efficiently. I want mention some of the names of their team who were especially helpful: Dai, Franco, Ernesto, and Jobani. There is also one other person that helped us significantly with electrical calculations. I can't remember his name, but I know he sits at the desk across from Dai. Our system has been up and running for a few months now and our electric bills have dropped from $500-$600 a month down to $16 a month. We could not be happier! Also, we just got an electric vehicle and are very excited to have it charging up on solar power. Not only did Infinium Solar do an excellent job, but the price was reasonable. We had talked to multiple different solar companies over the past 5-10 years and none seem equipped to take on the complexities of our project. We are super grateful for Infinium Solar and highly recommend them! read more

I don't usually leave reviews, but this company definitely deserves one. I had a simple job of removing my solar panels and then replacing them after a roof replacement. I'd recommend going with anyone else and if you can't find someone it might be faster to get a license and just do it yourself. Pros: - The eventually got the job done Cons: - Super slow, a simple removal + reinstall took 6 months - Expensive - Work is shoddy - Needed constant follow ups to get updates on the progress, usually they had not made any progress until asked - Not willing to take ownership when things go wrong First when they removed the panels, they also removed a solar water heater. However they left the pipes to the water heater open and uncapped so the water had to be turned off until I got another contractor to come and close the pipe. The contractor told me they had never seen someone leave a pipe uncapped like that before and it was extremely unprofessional. When it came time to reinstall the panels, I asked them if they had gotten a permit yet. They had not even started the process even though I had gotten requirements to do a permit as part of the initial job. They continued to tell me that a permit was not needed. I had to call the city myself to get verification that a permit was indeed required before getting them to start on the permits. This was 1 month after the start of the job already. Afterwards there was significant back and forth over a couple weeks for them to get all of the information they needed to get a permit. 6 months later they finally get the permit and the reinstall done. After the panels were back up, I checked the power output and the panels had 1/2 the output prior to being taken off. When I asked them about this they gave me a long winded answer to effectively say they weren't going to do anything about it. Ultimately I felt dealing with them any more wasn't worth the effort and closed out the project. read more

We are so glad that we chose Infinium for our recent solar panel and Franklin battery installation. From initial system design and quick permitting to the clean installation and smoothly passing city inspection, they exceeded expectations at every step. Infinium's work was done as part of a larger project on our house. Their team was incredibly professional and flexible, completing our installation in phases to coordinate with our overall timeline. We are so happy with our new system -- many thanks to Gideon, Nil, Ji, Dai, Stephanie and the rest of the Infinium team! read more

Recently we moved to a new property where the previous owners did not give any documents regarding Solar system. Reached Solar Infinium. From the first call itself, they were very welcoming and encouring that they will support till I get the PTO. The process started. Every week, I get updates (through email and phone call) from Lou on the status. This helped me not to be in dark and not knowing whats going on. They got the best Techincian ( Ruben and Dimitri). They both have very good energy, sporty, experienced and very easy to work with. When they come to the propety for any work, they know what they are doing. The whole team (Alvin, Renz, Kirby and other behind the scene) within Infinium are great. I recommend anyone who needs solar support, contact Infinium solar read more

Infinium Solar turned solar into a breeze. Instant responses, regular updates, and exceptional support every step of the way. The whole process was seamless and stress-free. When PG&E demanded a same-day meter collar replacement to clear inspection, they had it done in just a couple of hours. Special shoutout to: Tavee, my sales rep--super knowledgeable and always available whenever I called. Jerome, the project coordinator, who patiently answered every question I had. Dai/Ji, who made scheduling smooth and painless. Fernando and his installation crew--total professionals. Jiel, who provided fast and helpful post-installation support. Couldn't ask for better--highly recommend Infinium Solar read more

Alvin was very helpful in navigating the service I needed for our solar system and I appreciate his assistance and direct follow up.

I wish I could have written a review on my experience with their work but I couldn't even get a quote. Infinium was recommended to me by a friend who used them to put on a new roof and is now using them to install solar so I included them on a list of 6 companies I reached out to to get a quote for a new roof and consider for solar based on the quality of the roof work. They have a calendar on their website where you can schedule a consultation request which I thought was a very nice touch... except that after scheduling a time and date, I received an email that the roofer was not available and the earliest time he could come was 6 days later. Ok, fine. It is what it is.  I received an email confirmation that confirmed my new time and date with Angelo being my "Infinium Roofing Consultant". That time and date came and went and nobody showed up. Nobody called, texted, or emailed so after 30 minutes of waiting, I called and spoke to Alvin to let them know nobody came at my scheduled day and time. He checked the calendar and confirmed my appointment was scheduled and on the calendar then put me on hold to "make some calls". After a few minutes he got back on and told me their roofer was busy with a final inspection and would not be coming that day and asked to reschedule again for 2 days later. I told him that was fine but since we had already 5 other companies lined up so we might call to cancel if we made a decision beforehand. I again received an email confirmation with my time and date with Angelo again listed as my "roofing consultant". Since it was already scheduled, I decided to keep it even though we had already received 2 quotes by then. Once again on the day of my confirmed appointment, nobody arrived at my scheduled time. However this time I received a text after 5 minutes telling me "Chris the roofer" was running late and on his way with an ETA of 30 minutes (note every single one of the other companies that we contacted arrived early. Some even sitting outside in their cars so they wouldn't be TOO early). When he did arrive, it was not Angelo but someone from an entirely different company which I was not expecting. At no point was I told someone from a completely different company would be coming. Especially since my confirmation email listed Angelo as my roofing consultant and within that same email it states that Infinium does not subcontract. He did apologize for "the other day" and said he'd do his inspection and "get back to me". I never heard back from him. The other companies that came out to do their inspections all sent detailed quotes with photos same day or within 24 hours. After waiting 4 business days (6 days total), we signed a contract with another company. I find it a deceptive practice to claim they don't subcontract when they clearly do. I will not be recommending this company to anyone who asks. read more

Very timely and helpful experience, would strongly recommend for all your solar needs

I had a good experience with Infinium Solar. Jiel was helpful in getting a technician scheduled for the same day. Dimitri came out to the house, checked everything, and was able to find the issue. The service was good, and I appreciated the help from both of them. read more

I sent this exact message to you last September. Your only response was to ask for a review... This experience was absolutely terrible. I don't think anyone cared there. Poor communication. We had to call you many times, because we never knew what was going on. It took a year and a half to complete the project, because you called the city only once a week, not reaching anyone, and didn't work to get it taken care of. I was copied on the emails and you often didn't do what the city told you to do causing delays. We are very disappointed. You showed up at our house many times without notice. One time you climbed our roof to unlock our back gate and left it unlocked when you left. We have a camera facing the gate and watched you do it and saw every time you were at our house and didn't tell us you were coming. It was all very unprofessional. I asked to be notified when you were coming, but was not always notified. We need a battery to go with the system, but are afraid to use your company because of this awful experience. read more

Infinium Solar did a great job with my Franklin battery installation. They were referred to me by a friend who used them to install a similar setup to what I was looking for. The pre-sale visits were quick and efficient, and the plan came in as we discussed. They got the permits and did the installation shortly afterwards, doing the installation in one day very cleanly. Jiel and team were great in helping debug a configuration in the solar system that was preventing the solar from working properly when connected to the battery system. It's working great now. And Dimitri was great in managing the inspection with the city and making some final adjustments. I am very pleased with the job they did. read more

I had a red light on my Sunnyboy inverter. Sunnyboy wouldn't help me even though I had put in all my panels and the inverter as I'm not a solar professional. I called 4-5 solar professionals and no one called back except Infinium. They said that someone who knew about solar would call me and even gave me a time that they would call on the next workday. And Tommy called and he listened to me and gave me advice so that I could try to do the repair myself. He was very kind and patient. This outfit is great!!!! read more

we started with Infinium Solar the end of April. our first full month of solar our PG&E bill electric was under $13. our gas was also low at $70 because we prioritized using electric over gas because we could manage it with our battery backup. the support was tremendous. jiel justo helped us learn the system as I peppered her daily with questions and when I thought something needed fixing she was immediately on it sending Carlos who was great out to the field to investigate. Dai managed our process and kept us informed throughout. without Jiel's assistance we would have flounderEd great solar company and because they also do roofs we feel good about using them. read more

Initial experience was good in that they were responsive and quickly asked for a lot of details regarding my project, but after those first few days I've gotten thoroughly ignored despite reaching out multiple times.

Infinium did a full install on my roof of Maxeon panels and Franklin batteries. I'm very happy with how it turned out overall. Shoutouts to Ennar who drove the electrical and Jiel who helped with support. They were able to coordinate with my roofer to get the solar mounts in before the shingles went in so I could get a great install without having to screw through shingles, which I recommend. Response times and motion were a little slower than would have been ideal at moments. But I feel they paid attention to quality and I think it turned out great, and that's the most important thing. read more

Terrific experience overall. Infinium took care of everything from start to finish: panels, powerwall, permits, PG&E, etc. Easy. Very professional, took good care of our property/roof/etc -- even the little details like using ladder guards to prevent scratches. Mike, our consultant, came out several times throughout the project to ensure we had the right system to get our electricity bill close to zero. He dealt with any surprises nicely. Everyone was super friendly and responsive. System has been running for a couple months and we are thrilled. read more
