Exceptional, Best-in-Class Experience with Cinnamon Energy Systems: I chose Cinnamon Energy Systems (CES) based on their weekly podcast The Energy Show, their excellent reputation, and my positive history with Barry Cinnamon 20 years ago when Akeena Solar installed my original system. Now transitioning from NEM 1.0 to NEM 3.0, it was time for a completely new solar and storage setup. CES has been an absolute pleasure to work with from the initial pre-proposal all the way to securing PG&E Permission to Operate (PTO). My journey began in September 2025 when I contacted CES and was connected with Michael Croft. Michael truly listened to my needs, assessed my current system and usage, and provided a tailored proposal. Because I was waiting on some unreleased products, I delayed pulling the trigger and intentionally bypassed the 30% federal credit for personal reasons. Throughout months of follow-up meetings, Michael checked in consistently with zero pressure. When I was ready to move forward, he conducted a detailed site visit and delivered the final proposal. Once contracted, the operational execution was flawless. Paula Hernandez coordinated the project, sending Jonathan Munoz for the preliminary design and site verification (PowerWalls, main breaker, roof layout). Jonathan was personable and explained the engineering details thoroughly. CES then coordinated seamlessly with my roofer, sending a team to cleanly remove my old solar equipment. Paula kept me informed every step of the way; the team was always on time, professional, and a pleasure to talk to. Their dedication to customer service is unmatched. When a PG&E installed the Tesla meter collar, there was no power after install, Paula was actually on a trip to Europe. Despite being abroad, she immediately answered my text, rescheduled the PG&E install, and sent Jonathan back out to perform detailed troubleshooting on the equipment to ensure a seamless setup. Later, Lucas came out to install the ground rod and went above and beyond by proactively updating the firmware on one of my Tesla PowerWalls so it would slave correctly after commissioning. The city inspection process really highlighted CES's professionalism. Our local inspector, Leonard, is notoriously thorough, tough, and fair. Even in the rain, the CES crew was fully prepared. They proactively removed one of the installed PowerWalls just so Leonard could verify the mounting screws were perfectly secured into the studs. It paid off--Leonard meticulously reviewed the roof and drawings Powerwall outputs, ultimately passing the system and noting that the crew did an excellent job. The final hurdle was PTO, which PG&E approved in an incredibly fast four working days. However, turning on the export feature in the Tesla App hit a snag. After hitting voicemail on the phone tree and getting standard "it takes three days to appear" advice from front office staff, I happened to run into Jonathan Munoz in the back office. Jonathan and Paula refused to accept the "wait three days" approach. They immediately accessed my account, updated the backend settings on their end, and had me open my Tesla app--the export feature appeared instantly. From day one, Paula, Jonathan, Michael, and Lucas went out of their way to deliver a best-in-class experience. If you want a solar contractor with deep technical expertise, unmatched integrity, and true dedication to customer satisfaction, I highly recommend Cinnamon Energy Systems. read more

I recently worked with Cinnamon Energy Systems to install solar panels and a battery system at our home in Los Gatos. After getting quotes and speaking to over (5+) companies, Cinnamon was an easy choice. Early on I worked with Marcus (Director, Sales) and his team and they were extremely transparent and educational. Which is a huge plus, in a not very transparent industry:). Marcus in particular, was incredibly helpful in guiding us through many options, technically and commercially. Cinnamon ended up being well priced, with many solar and pricing options. We ended up getting a 24-panel Hyundai solar panel system paired with a Franklin battery - which for me was a better call as it's larger than a Tesla and works with my generator in the event of a long outage. The installation team was great as well, with the total install time only taking about 3 days. In fact, the entire team, including Paula in project management, Joanne in permitting, and the field crew--was professional, communicative, and easy to work with. They kept us updated every step of the way, from handling the engineering plans and local permits to managing the installation. They even offered a complimentary service to paint the new conduits to perfectly match our exterior walls. Also, Marcus did an awesome job walking me through all the agreements and process. All in all, super happy with Cinnamon and the system is fantastic. Great job! read more

I have been a customer for many years. For me one of the best things about this company is the support and follow-up. I've been very satisfied with them helping me optimize my set-up. Sometimes the settings are confusing. The Cinnamon Solar staff have been very helpful in resolving and or working on these issues. This is a company that will stick with you and help you. I have had an older system that they installed, replaced with a newer system and batteries. Also a SPAN panel. They have just been excellent to work with. For me the value of there support is what I want. read more

I run a business where customer service is extremely important through out the entire client relationship. The Cinnamon Team was top notch from pre quote, to need analysis, installation options, permitting, installation, education pre and post installation and follow through with PG&E connection. Michael Croft was our point person. He and the people behind him stayed on top of everything throughout the process. Would recommend them to anyone considering solar work. read more

Cinnamon met all our expectations. The Powerwall/solar install was smooth and on schedule. Michael Croft, our contact person at Cinnamon, provided great updates all throughout the process. He responded in a timely manner to all inquiries I directed to him. He also provided a great overview of the Tesla app that allows me to monitor the status of my system. I'm confident he will be similarly helpful to any of you contemplating Cinnamon as your solar installer. Brian Smith, April 2026 read more

Absolutely stellar process and service the entire way though. This was a more involved installation on a lightweight tile roof with multiple arrays. Split level home with some crawlspace work as well for the conduit. Did tiles break? Yes, of course, it was expected. Cinnamon made sure it all got fixed up properly afterwards. I thoroughly enjoyed talking to and working with everyone I interacted with through the process. Randy pointed me at the Hyundai panels, which actually made more sense than the RECs would have. Lucas helped verify that the layout would actually work. Paula coordinated everything superbly. Brian and Hector took good care of me as well. I showed their work to a few electrician friends and the response was "wow, that's someone who actually cared about making it look good". I am absolutely thrilled with the work Cinnamon did and would recommend them to anyone who wants to support a high quality local company that has fair prices and an all in-house crew. We've been up and running for about 7 months now and I have nothing to complain about, which is rare for me. Only hiccup was a microinverter went out, but they were quick to get it swapped out. read more

The team at Cinnamon excel at communication and execution. They designed our system as we spoke so we got to see everything unfold and explanations for every decision that was made. At every step of the way we were kept informed of what to expect. They handled all the substantial paperwork and inspections for us and it all went very smoothly. The installation was quick while also taking care to paint all the conduit so it blended in with the roofing. read more

Had a very good experience with Cinnamon. Randy was our contact. He was very knowledgeable and patient (we don't know much about solar and definitely needed some education). The communication was excellent. There are a lot of complexities: equipment, installation, location and number of panels, battery choices, dealing with PG&E etc. But we were never overwhelmed, Randy and other staff guided us through. Highly recommend. read more

Cinnamon Energy Systems delivers a truly premium solar installation experience, marked by professionalism, organization, and comprehensive service. From the outset, the process was seamless, thanks in large part to the outstanding support provided by my representative, Jessica. Her deep knowledge of solar systems, paired with her responsiveness and attention to detail, made the journey toward energy independence clear and stress-free. What sets Cinnamon Energy apart is their ability to manage every aspect of the project under one roof. They have established teams of roofers, electricians, engineers, finishing specialists, and logistics coordinators--all working in concert to ensure a smooth and timely installation. This level of coordination reflects a well-honed system backed by experience and a commitment to excellence. One of the most significant advantages was never having to worry about utility company coordination, particularly with PG&E, or navigating city permits and inspections. Cinnamon handled it all. They also made tax season simple by keeping all invoices and documentation in order, ready when needed. Every touchpoint, from initial consultation to system activation, reflected high standards of service and communication. I always felt informed, supported, and confident that the work was being done right. (Writing supported by Chat GPT, but formulated from my sincere experience.

TLDR: Cinnamon is hands down THE best company I have ever worked with in terms of house projects. Timely communication, amazing customer service across every single touch point, delivered as promised and with a smile. I like them so much I will have them quote a heat pump installation to make full use of my solar. If you are doing anything solar/green energy do yourself a favor and use Cinnamon! Project: Solar + Powerwall 3. Tight timeline! Full length version: Cinnamon Energy delivered a truly exceptional experience for my solar & power wall installation. Exceeding even my high expectations. I'm detail-oriented and selective about who I work with, and Cinnamon didn't just meet the bar, they exceeded it. We wanted to get solar+batteries installed before year end to qualify for the tax credit. I signed the contract on Oct 30th and Cinnamon delivered in exactly two months from start to finish! We just had the final permit inspection today, Dec 29th and it passed without any issues. Incredibly impressive given the tight timelines, dependencies on PG&E as well as city permits and Cinnamon juggling many other high pressure projects before year end. They didn't miss a beat! At every key step I had an email with updates as soon as the installation, PG&E visit etc was done. In fact by the time I got back to send them an email with an update they had already sent me an email stating that the milestone was done and what the next steps were. I have done many construction related project in my life and nothing comes even close to what Cinnamon delivered in terms of service, promptness, communication and quality. Marcus Shapiro, Director of Sales. My original salesperson was unavailable due to personal matters, but Marcus stepped in the same day I was about to sign up with another company. I really wanted to work with Cinnamon since they are local to me and the reviews I read were stellar. He worked fast, refined the quote, was transparent and honest throughout, and ultimately delivered a price I was willing to pay (higher than the other quotes I had. but I was willing to pay a premium since I believed a local company would service me better and it was my best bet to get it installed before the tax credit expired). So, I switched to Cinnamon at the last minute from another company, and I'm glad I did. Supporting a local company with leadership like this made the decision even easier. Paula Hernandez, Director of Operations, was outstanding. Her communication was immediate, consistent, and exceptionally clear. Every step of the process was explained thoroughly, with no gaps or uncertainty. It's rare to encounter communication that is this proactive and precise. Paula set a gold standard! Jonathan Munoz, Field Technician, did the site inspection and much of the technical groundwork, including installing the Powerwall, running grounding, preparing the system for install, and supporting the engineering plans for permits. His communication was excellent, his work was fast and meticulous, and when I requested the Powerwall be moved, he did it cheerfully and without hesitation. Professional, capable, and a pleasure to work with. For the final inspection, Frank Teague, Field Technician, arrived early and fully prepared before the permit inspector even showed up. He was incredibly helpful, took the time to explain everything clearly, and ensured the inspection process went smoothly. That level of preparation and customer care speaks volumes. What truly sets Cinnamon Energy Systems apart is their organization and end-to-end ownership of the process. From permits and inspections to utility coordination and final activation, everything was handled seamlessly. Communication was consistent, expectations were met or exceeded, and the quality of workmanship was evident at every stage. If you're looking for a solar company that operates at a premium level--with integrity, expertise, and outstanding people--Cinnamon Energy Systems is it. I would recommend them without hesitation. TLDR: Cinnamon is hands down THE best company I have ever worked with in terms of house projects.

Jessica is an amazing subject matter expert in the solar industry and really helped us understand what was needed at our residence and commercial properties to reduce our carbon footprint and save on utility expenses. The process was smooth and no change orders!!! read more

The team at Cinnamon has exceeded my expectations from installation to final walkthrough. They were in constant communication with me throughout the whole process detailing the steps they're on to steps forward. It started with Michael Croft as the front person that I had the pleasure to work with to the roofer who made sure that everything was satisfactory. read more

Cinnamon did a great job for us replacing, expanding, and adding whole-house battery capability to our solar system. Jessica at Cinnamon did a fantastic job speccing out the project, walking us through how the new system would work, where we could expand our capacity and matching our system to our energy use. We decided to replace our roof at the same time, and Cinnamon worked seamlessly with the roofers. The installation was done quickly and as expected. We ran into a glitch with final County approval, due to some personnel changes at the County, and this necessitated some rework. Cinnamon (Jack, Mark, Paula, Joanne and Jessica) were straightforward, proactive and transparent about this issue and we addressed it effectively. Our system is up and running and we love seeing how we are not using PG&E basically at all (for electricity at least)! One thing that is really great about Cinnamon is that everyone is very responsive. If you have a question or send an email they get right back to you with a real answer. read more

Very professional from start to finish. They handle everything. They are on top of things and they keep you in the loop. Michael Croft was helpful in explaining what would be involved and walked us through the process. read more

I got 6 separate estimates from local and national companies. Cinnamon Energy Systems was the second lowest, but they have also been around the longest and really know their stuff and they have been responsive all along the way. I started the process in September, made my decision in October and my install was completed in the first week of December. That was AWESOME. Everyone from the sales guy (Randy) to the scheduling staff (Joanne) to the electrician and install crew was fantastic, knowledgeable and skilled. Given the number of fly by night, shady and failed companies out there, it was really great to know that this LOCAL company is doing things right. For example, they don't just slap panels on your roof, they do it the right way with flashing, better rails, better components, and great skill. I'm pretty handy, but there is no way I could have managed the whole process through all the red-tape and paper work required by the city, and utility. Now I'm smiling because the 28% year over year electricity rate increase by PGE is now something I can scoff at while my house - even in winter - is running on a fraction of the imported energy (and cost). read more

Daniel and his crew were very responsive right from the time I sought their services. We got mini splits and main panel upgrade. They did a good job with both. Recently I had an issue with one of the units and Daniel, Paula and Sylvia were quick to respond and get me on the schedule. Oscar Moreno came to fix the unit and did a great job diagnosing and fixing the problem. Highly recommend asking for him. Overall, pleasant experience and would recommend them for any HVAC and or electrical work. I am very particular about certain things and there were some areas of installation that could have been done better but apart from that I had a good experience. read more

Cinnamon is a highly rated company and I was overall happy with the work. Sometimes communication was tricky but Consultant Michael Croft helped me navigate the process when clarification and service was needed. read more

We went with Cinnamon for a 12 panel system with Enphase micro inverters and two 5P batteries, and are very happy with the system and the support we've received from the company. They distinguish themselves from other solar installation companies by providing dependable follow through, reliable communication throughout the design and installation process, directly employing all workers, quality of installation, and by being a truly local company (based in Los Gatos). I highly recommend them to anyone considering solar in the Bay Area. The salesperson was professional, knowledgeable and helped us work through the options for our system. Of course, the sales people for ALL the solar companies are going to be super helpful because they want your business. One thing that Cinnamon did better than other companies during the sales cycle was to not pester us to death with calls and emails. Other companies continued to call repeatedly even after I informed them we had already signed on with Cinnamon. So irritating... Our Cinnamon rep stayed in touch but avoided being annoying. Also, unlike some other companies, Cinnamon didn't use any high-pressure tactics ("If you don't sign up by the end of this week, blah blah.") Where I believe Cinnamon really sets itself apart is how the company executes after the sale. If you've ever had a contractor that you had to keep calling, or who set expectations and then didn't follow through, you know how frustrating that can be. With Cinnamon, the communication and follow through was nearly spotless. There was one incident where the person coming out for our pre-design inspection was late and didn't call to inform us. But other than that, the company did everything they said they would do when they said they would do it (or earlier). Whenever we had questions, someone always responded promptly. They guided us through the permit process, inspection process, and getting our PG&E plan changed. At every stage of the project, our expectations were set and then met or exceeded. I am also very happy with the quality of the installation. The crew scheduled two days for the installation, but completed the job in one. The quality of the work appears to be very good. Everything was done to plan and all the components are laid out very neatly. Note that in the photos, Cinnamon offered to paint the conduit to match the house but we declined. One tip: if you don't want conduit visible on your roof, make sure that is part of the initial design (before you sign the contract) so the contractor can estimate the extra labor to hide the conduit as part of their work. Our house has old wiring, so we did experience problems with a few breakers tripping. It happened twice. This created some inconvenience because the problem occurred at night. For example, one breaker would trip immediately after we started our microwave oven. So that night, we had to heat our dinner in the oven. Inconvenient, but not the end of the world. But the electrician was able to resolve each incident the next day. Overall, the crew was professional and took pride in their work. And as I mentioned previously, everyone is a Cinnamon employee. I'm not saying all subcontractors are bad; I'm sure many do excellent work. But for us, having subcontractors in the mix introduces possible quality and reliability concerns, so we liked that all the work was done "in house." Since the installation, the system has been running reliably and we are delighted with it. I enjoy using the Enphase app to monitor the energy production and storage. I especially like the micro inverters so that I can see how much energy is produced by each panel, and because if one of the micro inverters fails, the remaining panels will continue to function. Again, we are very glad what we went with Cinnamon. I don't think we got the lowest price, but their price was competitive. We chose Cinnamon because we value supporting a local company and also enjoy the peace of mind that comes with knowing they do (and stand by) all their own work. read more

When the house goes completely black and subsequently, our entire solar system shuts down, one's anxiety level suddenly goes hay wire. Really?? This can't be happening. So, I contacted Cinnamon Energy Systems, my solar installer, and spoke to Paras Shah explaining that I had experienced a total outage; no electricity from my solar panels and no electricity from PG&E. Within 20 minutes, Paras dispatched Jonathan Munoz to my location to troubleshoot the problem. Jonathan recognized the problem immediately. A circuit breaker had been tripped. He reset the tripped breaker and the power was restored. We were so grateful. However, on the following day (Saturday) we noticed our solar system was not working so we texted Jonathan about the issue. Promptly, he indicated that he thought it might be due to a faulty inverter and a replacement was ordered. In addition to the new inverter, he recommended that the BUI (backup interface), be replaced as well. Once the replacement orders were placed and confirmation was received that the units had been shipped, Yvette Cisneros, their Service Coordinator, promptly scheduled the installation date with us. She was very accommodating and considered our schedules when making the scheduled installation appointment. Installation was set for 3/24/25 between 1pm - 3pm. From start to finish, Yvette did a great job keeping us updated. It was a relief knowing that she was always on top of things, allowing us to feel at ease. When Frank Teague arrived, the lead tech, we found him to be very knowledgeable, approachable, patient and willing to answer all of our questions and concerns regarding the installation. He walked us through each step thoroughly and as we watched, we could tell he was exceptionally skilled. Soon after, Emett arrived to assist Frank especially when the heavier of the 2 units needed to be mounted in place. All in all, the entire process was very seamless -- Everything worked perfectly on the first try! We want to thank the entire Cinnamon Energy team for being so attentive and ensuring customer service remains a top priority. read more

Cinnamon finished installing a heat pump and mini split system today, and we are very pleased. Oscar and Diego were very professional and hard-working, and went out of their way to make sure we were satisfied. When decisions needed to be made they explained things clearly, so that we could make an informed decision. They did a great job cleaning up at the end. We were very impressed with Oscar and Diego, and were very happy with their work. read more

Michael designed a wonderful solar setup for me. I am satisfied his expertise. I already recommend to my friends and relatives.

Cinnamon worked with us to finish the installation of a Tesla Powerwall in 2024. They were fantastic from start to finish, including in terms of transparency, pricing and execution. Marc specifically was our main point of contact and kept us well apprised, even when things got delayed. Absolutely glad to work with Marc and the Cinnamon team again. read more

I live in Utah so I am a long way from their service area but knew of the company through their podcast but when I had a problem with my system (installers long out of business) both Lily and Barry Cinnamon exchanged several emails with me to help me out. Considering they did all that while knowing they were not going to make any money from dealing with me, I call that excellent service. read more

Cinnamon Energy did a great job for a technology that is not simple! Jessica S., Design Consultant, who was always responsive by text and email, came out to do the site survey and explained all of the nuances of battery and equipment placement. She was obviously experienced and knowledgeable. Cinnamon scheduled the install at the earliest possible date, and the team came out and completed it on schedule. There was one problem with the app metering, which the Cinnamon team corrected forthwith, and the SJ inspection was scheduled very soon after that date. In short, the company was very responsive, and now our solar power is being used during the time of PG&E's maximum usage rates (evening hours) and not being given back to PG&E at their practically daytime zero rate on the (almost criminal) NEM3. read more

My entire experience with Cinnamon, who we used for our solar panel and back up battery installation, has been outstanding. Michael was a pleasure to work with--clear, patient, and a great communicator. Noelio and his crew did an efficient job with battery installation and hookup. I would highly recommend this company. read more

I chose Cinnamon Energy to design and install our new solar system for several reasons: 1) Reputation, 2) Helpfulness and knowledgeability of the salesperson, 3) Very competitive quote, 3) Local company. I am glad that I chose them. The installation process was virtually seamless. They were amazingly responsive and fast. The installation was done quickly and efficiently. They did a fantastic job coordinating with PG&E and Town of Los Gatos officials. The installation is very neat, and they restored my fence and the area of the wall around the new service panel to pristine condition. I am very pleased with the results. My system is generating enough power to run my house during daylight hours, and has significantly reduced the cost of charging my EV. The monitoring software works great. I have pessimistic tendencies, so I am a little concerned about the recent reviews on Yelp that claim that their warranty service is poor. Cinnamon would have to change from the upstanding Dr Jekyll into his evil alter-ego, Mr Hyde. I hope that I won't need warranty service, but if I do, I hope that they will be as quick and efficient as they were with the installation process. read more

My solar system was getting old, so I worked with Michael Croft and Cinnamon Energy to get it updated. They've been doing solar for quite some time as Barry Cinnamon's prior company Akeena installed my original system. The information session I attended was very informative. From the idea to the actuality, Michael answered all my questions and explained the process and time frame. I'm very happy with my new setup. I recommend Cinnamon Energy. They will be here when I need them. read more

How electricity works and how solar generation does its thing is a mystery. However, after determining we wanted to "Go Solar" we found Cinnamon Energy. We are glad we did. Not only a local company but the Cinnamon Energy's team is amazing. We began with Michael Croft who calculated and designed our system...He is a very patient individual suffering through all my questions (some I am sure were probably dumb) with a response that always was accompanied by a smile. In the office is Paula Hernandez who again, no matter what I asked, replied cheerfully, kindly and clearly. Sean, who did the installation at our home, went above and beyond. Staying late the night of installation to ensure everything worked correctly and also was a great help with my questions. Finally, Ramino who accompanied the County inspector for the final approval. He is a very dedicated and open person, willingly helping me. read more

I had a full system with battery installed in September We had a few issues with permits and there was some circuits not wired correctly. During a power outage the backup failed for an unknown reason- when trying to contact customer service there was no reply for a week Then when another issue came up they said $600.00 to send some one out Very frustrating experience- I would not recommend them read more

I have had my solar installation since 2002 and decided that i wanted to do some upgrades. My plan was to simply replace all of the panels on one string. This is only about a third of the number of panels i have. There was nothing wrong with the old ones, they were just old and only generating abut 50% of their peak output I had the pleasure of meeting John B. he came to my site to see what they could do. Having given it a good look over and reviewing my data, he agreed that replacing that string of panels made sense. He quickly got back with a proposal. Looked good and was the most cost effective available with great quality. Being an engineer myself and having worked with my system for so long, i decided that i wanted to get even better than the ones he suggested. I asked for LG's. No problem at all! He gave me a few options and we went forward. Also asked for some minor re-config of my existing system. No problem! I totally compliment the Cinnamon team for the work on this project. One of the other strings on my system decided to fail. They sent their best techs out to go through the whole thing and they got it all fixed up in a few hours. Keep in mind them coming out to do more debug was never apart of the original plan, so to have them come out and deal with my older stuff they didn't install was outstanding on their part. VERY professional imo. The whole system is up and cranking power. In an industry of other 'fly by night' and non-caring solar businesses, Cinnamon Energy Systems brought experience, very fair pricing, timely installation and outstanding followup support. Why would i want to use anybody else? Rock on Cinnamon read more

Cinnamon Energy Systems - Older existing string on the left, the ones on the right were replaced with LG's installed by CES(I'm looking for the pic of new ones) - Solar Installation Near Me - Los Gatos, California

Sales process was great and highly professional. Actual delivery was underwhelming and ended up taking 5 months from signing to installation, with no contact for 4 months afterward. For context: Cinnamon had advised after signing that the installation might be delayed as much as 30-90 months with all of the NEM2 installs. This made sense. But Cinnamon then went radio silent. At 4 months, I followed up and as best I could tell, my project had just been forgotten and made me wonder if I would have ever been contacted if I had not checked in. Ultimately, the project took 5 months - well into the summer we were hoping to have solar AC for and far longer than the surge estimate of 1-3 months. read more

Overall pretty pleased with Cinnamon's solar install. Their customer service is very responsive and great to work with. They made the process pretty seamless and there were no complications with getting everything approved by the city and coordinated with PGE. My one reservation is that their sales person explicitly represented that Cinnamon was experienced with installing panels on a metal roof before and would have no issues doing it here. Lo and behold, come install day, the team that installed the panels trampled all over and dented a brand new metal roof we had just installed less than a year ago. It was extremely disappointing, but Cinnamon was very responsive in responding to the issue and had our preferred roofing company come back and fix the roof. While the roof is mostly repaired, it's obviously not in the pristine state it was prior to the solar installation panel install. This is an issue more unique to metal roofs as you need to tread carefully on them to avoid denying them, so perhaps others won't run into this issue with a more standard roof. Overall we're satisfied and would recommend. read more

I cannot recommend Cinnamon too highly. Everyone, from sales to the final install and PG&E certification was personable, prompt, efficient, and knowledgeable. Our system is up and running beautifully with a Tesla 3 Powerwall battery. read more

Horrible. Had a technician come out to our property on Aug 2nd to take a look at our SolarEdge System which had stopped working. Tech spent 2 hours here to then say that the inverter needed to be replaced and that he would order it. 2 weeks passed, no word. Called multiple times/left voicemails to which no one responded. A month later.. Sept 8th, I had to start over with a new company since Cinnamon Energy had ghosted me. New company came out, confirmed that we needed a new inverter but when they tried to order it they were denied because Cinnamon Energy "had already ordered AND received it"! After a handful of continued attempts to get a hold of Cinn Energy again I finally got in contact with someone who told me that they did have my inverter and that if I paid them the initial service fee for coming out (which was $450) that they would give it to me! So essentially they held it hostage until I paid them for their incomplete job. Ended up just paying off the invoice so I could drive to their warehouse in Los Gatos to pick up and then haul home my 60lb inverter which mind you I still had to schedule and pay the new company to install. Cinnamon Energy was awful. Company I ended up using was Cobalt Power Systems who was great. read more

Poor Customer Support! Lost $$$!! System installation was delayed but OK. However, when the inverter failed during the highest production months of the year, it took them over 2 months to respond. This cost me over $1500 in lost savings. I had to hound them to get any kind of response, and the problem persisted after the "fix". I still do not have any explanation for the issue, and they will not provide any compensation for my lost savings due to their incredibly slow response. One employee blamed it on the fact that the CEO's daughter was part of the issue, and they can't blame her!! All of this occurred during my initial 12 month warranty period. Stay away! Any solar company can install a system, but components fail and support is the key to long term savings! read more

My neighbor had used Cinnamon to install her solar panels and was very happy with their work, choice of panels and price. We got a second bid just to see how it compared but ended up going with Cinnamon. Thad was great explaining our panel and battery options and the basics of how they would work. We ended up with 13 REC panels and a Franklin battery system. Before all this could be installed we needed to upgrade our old 100A breaker panel to 200A. We incorrectly assumed that PG&E would be quick to move the service drop and meter. Cinnamon was very understanding about this delay and when we finally could move forward didn't take long to come out. The crew installing the panels did a great job and were done in one day. The battery, aGate, sub panel, conduit and other necessary electrical parts took two days to install. All of this was done by Edwardo and Moses in one area of the outside of our house. It all looks well organized and easily passed inspection with Emit getting all the necessary signage on everything. The system has been in operation a while now and we are happy with it. There is a bit of a learning curve as to how everything operates and with our first power outage, just 1 1/2 hours, we discovered that we needed to make some changes in the circuits that are backed up by the aGate. Cinnamon has been very helpful about making these changes. Everyone we have come in contact with in the office has been wonderful. Yvette, Joanne and Paula are well organized and quick to get paperwork completed and to answer all our questions via email. This is a really good company and we very definitely recommend them.

In the last decade, I am a 2-time customer of Cinnamon Energy Systems (previously known as Cinnamon Solar). I've went with Cinnamon to install, in 2014, a 6 kWh system, and in 2016, an 8.4 kWh system, at two separate locations, as I moved from one home to another in the Bay Area. First off, Barry Cinnamon has a wonderful and solid crew. He's built a team around him that's able to assess your home's solar capabilities, draw up a realistic proposal, perform the installation, and follows up with your installation experience. Barry is also active with the Sacramento's Energy-related initiatives, fighting on behalf of homeowners, hence he foresees upcoming changes from lobbyist activities, influencing upcoming legislatures to help homeowners, and is fully engaged in opposing PG&E's unfavorable rate changes. Anyhow, during both my onboarding process with them, I've interacted with Scott O. and he's able to map out my roof close up (recently with a drone) and make a realistic estimate of my homes' energy probable capabilities throughout a year. Appointments and callbacks are also well organized, with Christy and Paula, helping with follow ups, scheduling and routing requests to the right personnel. Jonathan M. and Felipe are out on the field and they are personable, courteous and highly professional. The installation process seem daunting at first, with timelines charted out with multiple dependencies depending on my situations. Scott carved them out clearly to include time estimates and expected delays, from panel order wait times, to multiple visits by city inspectors, to scheduling in electrician contractors, etc. Your experience may vary, but under both installs both home locations, they were both well within the estimated timelines. There's also post-installation services where they responded swiftly. The solar systems never had any issues with the energy production within expectations, but I can't say the same about my roof which needed some repairs. Barry's crew responded swiftly to help me triage the situation and resolved it within a week (with some pretty major roof work). The entire crew are diligent, hardworking, friendly, observant and quick. Cinnamon has a solid team going. I hope you'll experience the same with them as you go through your home's transition to solar energy. read more

A few months ago I had a battery and transfer switch installed by Cinnamon. They did a great job. Last week I had a problem with the main inverter ( not their installation) and they responded immediately, had a great technician come out promptly and fixed the system. Every person in this organization is extremely professional, responsive and polite. a great company to do business with. read more

After the lengthy storm window Northern CA has experienced the past few weeks and having a 2.5 day and 4 hr PGE outage in our area, the Cinnamon Solar delivered as designed and promised, Our 16 KW battery and back up circuits kept us with power, with minimal inconveniences of moving a couple appliances to the back up circuits while functioning normally in our daily routine. The Solar Edge App automatically changed our charging % to 100% battery ahead of the storm, which kept us supplied with plenty of power to "weather the storms" 7 x 24. Keeping the furnace working was great, no need to use the wood and fireplace as the last resort backup for the lengthy 2.5 day outage. We were able share power with our neighbors to help keep their phones and computers charged. We offered for people to come over and warm up, but most were using their fireplaces for one room warmth. Very happy with Cinnamon Energy results! read more

After my initial review, we received an email and a phone call from Barry. He was apologetic about the incident and he mentioned that he had received my email and had asked someone to follow up on it. A technician came by and found that indeed there was an issue and a replacement part had to be ordered. They installed it on a followup visit. Since then we have not seen any 'Insulation failure' issues since then even though we had a couple of days of heavy rains. It does appear that the ball was dropped by someone on their side, and it's good to see that Barry cares about his customer base, the and that he was able to sort out this issue. read more
