Robert C. came to my home and went over the advantages of adding a few more panels that would still keep me in tier 1 status with the power company as well as consideration of adding a Powerwall III battery. Considering the increased power generating capacity of newer panels and storage capability of the Tesla battery, I was sold by the quality and value of the expanded system. The design and contract review was done online in a timely fashion and it was a swift transition to installation taking place in just one day, as the the lead installer (Antonio) was joined with two co-workers who explained how the project would move forward and answered all my questions. The work was complete by 3pm and I was extremely satisfied with the entire process. Thank you Semper Solaris for a quality job for a fellow veteran. Dan

In 2024, I replaced my router which set off a chain of events. I was unable to connect my new router to my solar panels. I called Semper Solaris, who directed me to call Enphase, who directed me to call semper Solaris to send a technician after their troubleshooting did not work. I even reinstalled my previous router with no luck. Short story, I called Semper Solaris and they schedule me a technician for a whopping $500 service fee upfront without even diagnosing the problem. Not covered by warranty and per their management about waving the fee or reducing the fee, "Sorry, nothing they could do." I cancelled the technician. This was in 2024, and I have not been able to connect to my solar panels since then. Buyers be aware

I want to start by saying I don't understand all the negative comments. People with solar systems…read morethat are years old and complaining about Tru Up bills.. the prices from PGE have gone up dramatically over past few years and you need to still use energy conservation once panels are installed. Lastly, financing anything comes with additional costs. A great way to avoid the finance charges is pay cash or get your own loan under terms that fit your financial needs. It is my understanding that 1st Light Energy does NOT finance solar systems but outsources that for customers who need/want to go that route. After considering these three facts let's move on to my review. Garrett was my point of contact person and he was upfront about the costs versus my savings. He called a month prior to my appointment for installation because he had a cancellation and I was able to get them installed the same day! Any questions I have had he is a email away and has been friendly, honest, and helpful. Fast forward three years I have now installed panels again on my second home. Same great company and customer service. Same situation where the company had a cancellation and I was able to get my panels installed sooner than expected. A year from my second installed panels has past. I never had done a review and realized it was time to do so! Fun fact, this is a small local business that the owner and his brother (co-owner? Idk ) both work at. I highly recommend this company!

I am filing a complaint against 1st Light Energy for poor service, excessive fees, and lack of…read moreaccountability. We discovered a roof leak and, not knowing the cause, contacted the company since they installed our panels. Their response was that "if it didn't leak when the panels were installed, then it's not our problem," and they even wanted to charge us to send a technician. We were also told it would cost over $10,000 to remove and reinstall the panels so repairs could be done--an outrageous quote from the original installer. Additionally, they said our system needs to be upgraded from 3G to 5G for monitoring. The panels were originally installed with 3G towers--standard at the time--but now they want $800 to switch to 5G, claiming it's "no one's fault but the government." This is unreasonable; a reputable company should stand by its installations without shifting blame or costs to the customer. Our assigned representative, April Miner (aminer@1stle.com), was rude, unhelpful, and dismissive. Every request for clarification was met with deflection. Instead of offering solutions, 1st Light Energy continually finds new ways to charge customers additional fees. We were promised a 25-year warranty, but it appears to cover nothing. Each step of the process--removal, reinstallation, inspection, and basic upgrades--comes with another charge. It's clear this company's focus is on profit, not service. At this point, we question the point of having solar panels if we're forced to pay thousands just to maintain them. This is not the integrity or support customers expect from a company promoting "sustainability" and "long-term reliability." Homeowners, beware: 1st Light Energy offers poor service, an empty warranty, and constant hidden costs.

We could not be more delighted with the results we achieved working with the team at Your Energy…read moreSolutions. The many moving parts to our residential solar plus battery system, including the various entities, such as PG&E, Tesla, City inspectors, and the financial backers we opted to use all progressed seamlessly and, for us effortlessly, thanks to hard working individuals behind the scenes. In particular, Skyler could not have been more helpful, managing our project and acting as a point of contact. Others included David in sales who demystified the process, Varon who coordinated with the utility to ensure we met all requirements, and Gino, who collaborated with Maxwell Power (formerly HDM Renewable Finance), the clean-energy company that helped finance our residential system. On site, the design and install team did a great job keeping things simple. The entire system, including battery and thirteen panels, was installed according to Ramiros's expert design within just four hours. Good quality hardware was used to tie to the roof, which was inspected by our roofer and given a big thumbs up for not causing problems. But even before that, David our site survey tech, gave us the sense that all would proceed well, as he collected necessary data by drone, and made a favorable first impression with his personable approach. Toward the end of the multi-month process, which included time to get a new roof installed, we passed city inspection with YES tech, Dario, an extremely courteous young man, present to ensure we made it through that last step and PTO (permission to operate). YES has an excellent and well-deserved reputation because of these people and others who worked on our behalf. The company can do better automating some of the process, and to be fair, they say they are working on transitioning to a CRM software solution for this purpose. But, I can say that over a period of several months, I had excellent communication with many helpful people. Skyler in customer service was my primary contact and that made all the difference. My thanks to YES for helping us make this wonderful and complex project a reality. We love our new YES-backed system and look forward to working with the company again in the future.

I had a frustrating experience with Your Energy Solutions regarding a warranty transfer. The…read morecontract stated that an additional charge would be incurred for the warranty transfer but did not disclose the amount. We were later charged $500 with no prior breakdown or explanation of the fee. I clearly communicated that I would be the one paying this charge. Despite that, the service department reached out directly to the buyer and asked who would be paying. This unnecessary contact created confusion and complications during the escrow process that could have easily been avoided. The lack of transparency on the warranty transfer fee and the poor internal communication caused more stress than necessary. Businesses handling real estate-related services should be more careful with both contract clarity and how they communicate with parties involved in a transaction.

PG&E will need to upgrade transformer (December ???) before we can send greater that 2000 watts back to the system. Right now, we have conditional permission to operate, limiting output to PG&E to 2.2 KW.

We were interested in solar for our 1940s home and provided a deposit in good faith. However, after further inspection of our roof and the overall project viability, we decided not to move forward. When we requested our deposit back--before any equipment was ordered or installation began--the company initially refused, claiming it was 'passed' the point of a refund. It was a high-pressure situation where we felt they were trying to lock us into a contract we weren't comfortable with. While we did eventually receive our deposit back after pushing the issue, the initial refusal to return funds for work not performed was a major red flag. Homeowners should be very careful with the fine print here. If you are looking for a company that values transparency and customer comfort over just 'closing the deal,' I would suggest looking elsewhere. We're glad we didn't get stuck with them and are instead putting that money into improvements that actually fit our home.

He was extremely knowledgeable about solar and made the process of designing our system straightforward and easy. Because I had travel plans, we couldn't start immediately, but the Syndy team scheduled our installation for Jul 27 - 28. Everything went exactly as planned. The materials arrived on Jul 24, and Martin and his crew, showed up right on time at 7:45 AM on Jul 27. They worked incredibly hard, efficiently completing most of the installation that day and returning the next day to finish the remaining panels and cleanup. That evening, seeing our panels generating solar energy for the first time was an amazing feeling! PG&E installed the Tesla Backup Switch a few days later, and everything seemed to be moving perfectly - until our Livermore city inspection on Aug 7. Unfortunately, we failed because an approved heat detector had not been installed. I was extremely disappointed. It felt like having an amazing present sitting right in front of me but not being able to open it! There were a few additional hiccups, but Jason stepped in, took ownership of the heat detector issues, and worked to get everything resolved. We finally passed inspection and received our permit on Aug 26, followed by PG&E Permission to Operate (PTO) on Aug 28. A huge thank you to the entire Synergy Power team: - Martin, Eliel, Manuel, and Nate for the excellent installation - Rebekah, Melissa, Mark, and Amy for keeping us informed - Jason for stepping in and getting the final issues resolved Overall, we are extremely happy with our solar system and grateful to the entire Synergy Power team for seeing the project through from start to finish. Thank you, Synergy Power, for a job very well done!
