    I have a TON of panels and two EV's so you could imagine the relief when TSP got everything working perfectly in ONE DAY!

    The company who I pay for my panels has been an absolute nightmare to deal with. Panels haven't been producing due to a faulty inverter for over 6 months! Over a month of back and forth sending pics and listening to their scripted excuses. They had the audacity to say "if your bill is a couple dollars, your panels aren't producing" WTF? How is that a method to monitor output??? $600 a month later in try up bills, I got tired of calling and yelling at them so I gave up. Enter TSP. They SAVED ME! They diagnosed my problem and installed a new inverter within days with an app so I can monitor my panels output! They even offered to fix some broken tiles I have that let water through but I'll get that done before winter. Now I have a brand new inverter and monitoring that I didn't even know was available! Thanks soo much to Mario and Junior! Ya'll saved me soooo much time, money, and STRESS! A++++

    Roof Repaired!

    I can not recommend Mario & The Solar Pros enough! I used another Solar Installer originally, and unfortunately they caused multiple leaks and damaged my roof when installing 26 panels. I've since learned the only way to go when installing solar, is to avoid the big companies (I used KOTA) and hire an experienced roofer certified in solar (like Mario)! You have 30,000 to 50,000 dollars over your head in roofing, protect it from big solar companies, ie amateur roofers! When it was obvious my previous company was not going to fix it (nor would I trust them to), I called the best reviewed East Bay companies for bids to fix the damage and reinstall the system. First off, Mario answers his phone himself, and can competently and honestly answer your questions. I got his bid in days, everyone else was weeks. He inspected it the next day, the others were weeks. He fixed the cover plate with the largest gap (sticking up in the air), and a few broken tiles with ones he happened to have in his truck just to be nice while inspecting my roof. Who does that? Mario! He greatly reduced the worst of my leaks before I hired him, and that saved me a lot of money since I was no longer getting so much interior water damage each rain. Mario worked with me on the price, and was 100% in line with the competing bids. After the job commenced, he proved each day I was an important client, answering my questions, and making sure his crew delivered as promised. He took pictures everyday of the damage they found (for my lawyer), and the progress on the reinstall. The materials he used are light years ahead of what I had (going from tar paper to high temp peel and stick underlayment). His crew started work a day or two after hire (other companies gave me estimates of 4 to 6 weeks), they worked hard each and every day, and they even came on a Sunday because there was a break in the rain. This dedication again saved me money, since each day was a day without solar. I could not have asked for more from his crew. Finally he came to inspect the work with me when the job was done, and they did exactly what we agreed. He not only fixed every leak, made my roof look new, and reinstalled the entire frame system perfectly, he improved my solar production. He repositioned my most powerful panels (I have 400w and 360w) where they would get the most sun, and added an extra string to my install to ensure there were no issues like I had in the past. My solar is back up and running better than ever, and I am so impressed with the roof work they did, I asked for a bid to upgrade the rest of my roof. His workmanship, experience, and 10 year warranty are worth every penny!

    They shared photos of the work done and all of the fixes and adjustments made

    Got Watts installed two phases of solar panels on my roof, 67 panels in total. The job was massive,…read morethe price was fair, and the follow up service was excellent. 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.

Kudos to the entire Got Watts team, from Joe for the site survey to Tim and his install teams and Marc for the final inspection/walkthrough and Mallory, Jenn, and Lindsay in the office. The team kept in constant communications throughout the entire process. The install team did excellent work to make sure everything looked good and functioned correctly. They were exceptional in their craftsmanship to install the system and went the extra mile to minimize any changes to the outside appearance of our home (almost an invisible installation!) We are 100% happy we chose Got Watts for our Solar and Battery solution!

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.

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.

Btw I was going to bump this review to a 4 but working with Nick we decided on 5.** We had a complicated full house renovation this year and signed with Clean Solar for either the Tesla tiles or solar panels and we ended up choosing solar panels + Tesla power walls. I want to give special thanks (and the only reason why I didn't give a 0 star) and appreciation to the members listed as they deserved beyond 5 stars Bill, Nick, Jeremy, Rodger, Louis, Kevin, Albert, Alberto, Carl (CEO). Bill was amazing and helpful in explaining the process and helping us secure the initial funding. You are probably wondering why I am giving this solar company a 3 star. Well it takes 1 bad apple to ruin a team and this is the case. A three day project ended up taking 3+ weeks & we understand that the workload is extremely busy this time of year. However when 1 person is acting unprofessional, crossing the line, asking homeowners to borrow a usb cable to charge their cell phone, super loud, tries to impress (why), doesn't listen to clients (would walk away in mid conversation), act as if he is the owner of the company, talks way too much (not in a good way), talking about his side hustle business, a bit juvenile, not completing and complaining about the job in front of clients plus not showing up when he said he would to complete the job, leaving tools at the site and asking the homeowners to put it in their garage until he returns to pick it up, calls in sick last minute leaving the load to other team members plus more well then this becomes a problem and 0 stars (if possible) especially the amount of money you invest into this project. We also requested that this person not show up again but they kept sending him back. At the end of the project half of the Tesla walls were connected and working but the other half wasn't connecting. At one point our bedrooms electricity didn't work, it wasn't the breakers and Nick was awesome enough to take our after hours call and help us manually override those other 2 disconnected wall panels. The dream team (Nick, Kevin and Albert) resolved the connection and all is working now. Also, Nick stayed late to make sure our Tesla walls were configured and updated properly. Plus , a shout out to Jeremy for staying late as well to help fix a broken issue. Feedback: Organize a team that works well together to effectively complete the project. Provide sexual harassment training (this is excluding people listed here). If a female client doesn't feel comfortable with a person don't resend them back. Also if a homeowner (regardless of being the wife) calls and leaves a message please out of courtesy call back after all I am the client, work and pay the bills too (even though this is my husband's project).

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.

Solar optimum offered me Panasonic solar panels with a warranty guarantee from Panasonic which essentially guaranteed that as long as Solar optimum or any other certified installer installed our system that even if Solar Optimum were to go out of business, Panasonic would pick up the workmanship and product warranty for 25 years - this was something that no other company I reached out too could offer and to me made it clear that I wanted to go with Solar Optimum. After install Panasonic did send me a warranty certificate warranting the panels should Solar Optimum go out of business. The system works well. In its first year it significantly outperformed the estimated production by about 3MWH and YTD it will soon pass the production estimate for the entire 2024 year. There were two big issues when working with Solar Optimum - communication was brutal and would constantly be a back and forth of unanswered emails, non returned phone calls, and overall poor communication. The second issue was after install the installers drilled holes too deep and through my ceiling drywall and coordinating the install team to come out and fix it wasn't easy and took longer than it should have - when they finally came out to patch my drywall they smeared over some putty in the 8-10 holes, didn't paint it and didn't try and match the patches with my roofs texture leaving that responsibility with me. However because they're a smaller company there are far less mark ups compared to other solar companies and the price was far more competitive than any other company I cross shopped with an outstanding Panasonic backed warranty.
