There were hardware glitches after installation, but the Got Watts team reliably spotted them - without me realizing there was even an issue - and sent teams out to ensure my equipment worked as promised. Years later I noticed some leaks through my roof where some phase 2 panels were installed. I notified Got Watts and they sent large crews to my home to rectify the issue over several days. This was no small fix. They probably spent vastly more to rectify the leaks than they did to install the panels to begin with. No one likes to have problems with an install. But, it means a lot for a contractor to honor their commitment and spend vast sums to honor their warranty, and their word, to their customer. I've had "good companies" make promises they wouldn't honor once the initial check cleared. Got Watts was true to their word and treated me in a dignified manner that is rare these days. I would unreservedly recommend the good people at their firm. Special thanks to Sam Moore and Daniel Harrold for their excellent service.

Having East Bay Power Systems design install and certify a rooftop solar panel system has been a…read morewonderful experience. Working with the team (Darlene, Jeff, David etc.) to get the system designed and installed was very easy, they took care of everything, including getting the city to approve the design/installation for PG&E. Installation was a simple one day process, and best of all, we were essentially off the grid the next day. Interestingly East Bay Power Systems use American made solar panels (Aptos) and an American made power backup system (Tesla). Not only does the system perform flawlessly, because of there high output of the Aptos solar panels (up to 450W per panel) the whole array of 10 panels is virtually unseen. As an added bonus, they set up a Tesla app on your phone so you can see at a glance how mush power the system is generating, how much is being used to power the house, how much is used to charge the backup system and how much power is being sold to PG&E. For a system this good, overall cost was relatively low, far less than what I was quoted 5 years ago by two different companies. You may have noticed all my reviews to date on Yelp have been 5 star, this is deliberate. Life is too short to focus on that which does not make us happy. This is why I restrict my reviews to those things/places/services that make me happy and appreciate life.

Finally, Kara engaged and we got the Permission to Operate about two months after the install. Supposedly Jeff (the Business Owner) is no longer with the company and has gone back East, so not sure who is leading their future efforts.

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.

My mom and I couldn't be happier with the service we were provided from start to finish. We contacted the business in late July of last year to see about installing a solar system on our home before the end of the year. Within in days, Alessandro was here to meet us in person and provided us with a comprehensive breakdown for solar options and pricing. We loved that we were treated like actual people instead of a number in a queue. Given that there was a slight backlog of jobs they had to work through we were assured that we would have our system fully installed and activated before the end of the year, which we did! It was great working with Nick who was our onsite rep and Juan was always available to answer any questions we had by phone (of which I had many). Despite the number of times I called, he was always patient with me and provided detailed answers that gave me a better picture of our installation and how our system would operate moving forward. I can't say enough about how amazing the whole process was. Looking at our electrical bills right now and we're in awe of all of the savings we're getting, which validates our decision to purposefully oversize our system. If and when we decide to install a car charging station in our home we're definitely going back to Sunlight!

I can't say enough good things about Carlos Gomez from Sunlight Electri-Cal Solutions…read more I've been working on a non-standard solar setup using an EcoFlow Delta Pro Ultra X and EcoFlow Smart Home Panel 3, and finding a contractor who truly understood this type of system was incredibly difficult. I spoke with many contractors, and almost all of them sent salespeople who gave generic answers or tried to push cookie-cutter solutions that clearly didn't fit my setup. Carlos was completely different. From the moment he arrived, it was clear he wasn't a salesperson -- he's an engineer, and it shows. He took the time to deeply understand my system, reviewed actual spec sheets on the spot, and immediately identified issues that other contractors completely missed. Multiple companies told me Hyundai panels would work fine. Carlos checked the amperage limits, applied proper safety margin calculations, and clearly explained why those panels would not work with my EcoFlow system -- saving me from a costly mistake. He also walked me through: Proper panel selection within voltage and amperage limits Safe string configurations and series wiring How to maximize roof space while staying within code Permitting requirements I hadn't been told about before On top of that, Carlos identified critical code and safety requirements that no one else mentioned: Bollards required in the garage to protect battery units Correct battery placement to maintain required clearance from doors and entrances Heat detector requirements for battery installations in a garage These are all things that would have caused inspection failures later -- and Carlos caught them immediately. He spent well over an hour with me, climbed onto my roof to check for obstructions, inspected battery placement, reviewed wiring paths, and answered every question in detail without ever rushing me. What truly sealed the deal was how efficient and transparent the pricing process was. Carlos was able to turn around a detailed quote very quickly, and when I received it, I was honestly surprised -- it was a significant amount lower than every other quote I received, even though his evaluation was by far the most thorough. Given everything: His technical expertise The level of detail and care The ability to integrate with my existing system The fast turnaround And the much better pricing Choosing Sunlight Electri-Cal Solutions was a complete no-brainer. Carlos is knowledgeable, meticulous, honest, and genuinely passionate about doing things the right way. After meeting him, I completely understand why this company has such strong Yelp reviews. If you're in the Bay Area and need electrical or solar work done the right way, especially for a non-standard or custom system, I highly recommend Carlos and the team at Sunlight Electri-Cal Solutions.

Thank you to Dan Moran, our project manager, who was always available whenever I called with answers or solutions. Dan has a very calm demeanor and an easy flow in explaining different processes and how the system and the app work. I really appreciated Juan Carlos, our electrician. In addition to upgrading our panel, he had to do a couple of hole patches in our wood siding , which is out of his general scope of work , but did a nice job at it. Juan was very thorough and I appreciated his cleanup when he was done.There was no scraps of wire, electric tape, nothing left on the ground, which was very much appreciated. And as a side note, there are four houses on our street who have used Northern Pacific Power for their solar needs. Which I would think in itself, is a pretty good recommendation.

Five stars for the installation -- outstanding project manager and crew: responsive, punctual,…read moreprofessional, top-quality work. One star for the sales process. When we raised concerns, I believe the salesperson my partner dealt with wanted to make things right, but sales leadership stepped in, dismissed our concerns as unfounded, and offered nothing. Those concerns were (and still are): 1) Sketchy contract execution. NPP offers a 5-year prepaid lease in partnership with Balto Energy. It lets homeowners offset installation costs because the leasing company collects a 30% federal tax credit (no longer available to homeowners) and, in NPP's words, "monetizes that tax credit over 5 years." The contract was executed by sending the DocuSign to just one partner, with all owners lumped onto a single signature line -- one person signing on behalf of the other. For a married couple in California, that's legally questionable under community property law, given a) the encumbrances placed on jointly owned property, and b) no power of attorney authorizing one spouse to sign for the other. I never saw the agreement until installation was underway. 2) Misleading claims. My partner was told, verbally and in writing, that we'd "own the system outright" at the end of the 5-year term. In truth, the contract contains only vague language about a fair-market-value buyout, with no detail on how to initiate it or who to contact at end of lease. We've had zero contact with Balto through this entire process -- only NPP -- yet NPP's sales director told us they have no role in the lease agreement once it's signed. In other words, they don't stand behind the product they sell. Don't be like us -- do your diligence (especially if you're over 65 and new to solar leases), verify every claim against the actual contract language, and make sure all owners review and sign every agreement.

He found many savings and benefit enhancements along the way. In spite of the solar credit expiring at the end of 2025, David put together an HDM plan far superior to anything I found when getting competing quotes. It simply lowered the cost without complicating ownership or savings or adding any ongoing cost. Speaking of competing quotes, they beat everyone else. All together, I saved about $20,000 without undue complication. Production Manager Jack kept me fully informed along the way. He always responded promptly and clearly to every query. He scheduled and completed the solar installation much earlier than promised. The installers also travelled a long distance outside of their service area to do the job in the Sierra foothills. So, even if you think your home is outside of their service area as shown on Yelp, you might give them a call and see if they can do it. Installer Gio and his team were excellent. Our panels were going on a tile roof and I had concerns about the L brackets pulling up the tiles as they slide under the downhill side of tiles. They ground channels into each of the affected tiles for these brackets so that the roof is still as water tight as a duck's a**. Gio, the electrician and main contact on site was both smart, friendly and patient in explaining the details while the solar panels, Tesla PowerWall batteries and solar inverter were installed. I'm now using Tesla's app to monitor the whole system, which is working perfectly and is fascinating. I couldn't be happier. Thank you, Simply Solar!

DO NOT DO BUSINESS WITH THEM. This company operates in bad faith and will bait-and-switch you. I…read moreWILL BE REPORTING THEM TO BETTER BUSINESS BUREAU TODAY. We originally chose them a few years ago because they offered free solar panel removal and reinstallation when we eventually needed a roof replacement. The initial install went fine, but trying to get them to honor their contract now has been a nightmare. Bait and Switch: They are suddenly demanding a $3,600 fee for the removal. Even their salesperson admitted this fee was not indicated in our main agreement from 2021, but is now picking apart vague fine print (outside of our contract) to justify it. We have sent the contract over multiple times and asked them to highlight the language where it specifies this charge. Unethical leadership: Leadership is aware of this $3,600 gap, but they don't want to back down. Terrible Customer Service: They are dragging their feet and refusing to coordinate with our roofer, who has been consistently asking for dates to remove the solar. Ignored Emergencies: We explicitly told them we have an active roof leak and asked them to prioritize the removal so we could fix our home. They did not care. Once they finish your initial install, they will abandon you and refuse to give you the time of day. I am reporting them to the Better Business Bureau. If you are looking for solar, be very wary and look elsewhere.
