United Solar Electric

Highly Recommend United Solar and Ben Vanni!

I highly recommend United Solar and especially Ben Vanni. I first worked with Ben about six years ago when we installed our original 14 solar panels. We had such a positive experience that when we decided to expand our system, I reached out to Ben and United Solar again. This time, we added another 16 solar panels along with two Tesla Powerwalls. Once again, Ben and the entire United Solar team did a great job. The installation and inspection teams were professional and efficient, and the whole process went very smoothly. Ben kept me updated throughout the project, communicated clearly, and was always willing to answer my questions. I also appreciated that they kept their pricing competitive while still providing excellent service. After working with Ben and United Solar twice over the past six years, I can confidently recommend them. Great service, smooth installation, good communication, and a team you can trust. Thank you, Ben and the United Solar team!

United Solar Electric installed my Solar Panel system and did a great job. They were competitive on the pricing, installed the system exactly as I wanted it and did it quickly and efficiently. I will use them again if I ever need another Solar System.

After considerable research, I chose United Solar Electric to install our system. They were very professional, reasonably priced, installed high quality products with long warranties, and got the job done on time. I definitely recommend United Solar Electric if you are looking to install a solar system in your house.

My wife and I purchased a new 19 panel solar system and Tesla Powerwall in mid 2025. The install was completed in October 2025. The crew and all of the people at United solar Electric were very responsive and professional. I would, and will do business with them again, (adding an additional battery). PG&E was a problem. PG&E was very slow with providing PTO (permission To Operate). We did not receive PTO until end of May 2026, over 6 months from the date when system was operational. 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. To United Solar Electric's credit, they were with us the entire time dealing with PG&E and were just as irate with PG&E as we were. Thank you, United Solar Electric!

United Solar Electric has been helping us install a pretty robust solar system with battery back up. Ryan was so knowledgeable and patient from the very beginning. He walked me through all the options and really understood my household needs. I feel his prices were fair. My house is now completely electrical, no gas. And I'm 100% confident that this system will save us money in the long term and help us keep power on during power outages. And during this project, Holly and Anahi were amazing in keeping our project on track and coordinating all the minute details with our GC. I actually really want to go to their office just to say thanks. Their installers were always professional and understanding when we had to interrupt their work multiple times through out the project. THANKS Will upload pictures soon.

My wife and I had a very concerning experience with United Solar Electric regarding their business ethics and refund policies. 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.

Highly recommend United Solar

It was great working with Ben Vanni for speccing out and coordinating our 12 kw solar install in Pleasanton CA. I chose all top of the line equipment including REC panels snd Enphase microinverters. United Solar are real, good folks to do business with.

We recently had an Enphase solar system installed by United Solar Electric and had a great experience from start to finish. Their team demonstrated expertise across all phases—design, permitting, installation, and securing utility permission to operate. Their pricing was competitive with other quotes we received through EnergySage, and they came highly recommended by a friend. While a few issues arose during installation, they handled everything smoothly and professionally. Special thanks to Ben, who was consistently responsive and dependable throughout the entire process.

self consumption system

United Solar in Castro Valley absolutely nailed my solar project! They were super helpful, especially since I have an existing NEM2 system and a tricky tar and gravel roof—no other company was willing to take it on. Their suggestion to focus on self-consumption was a game-changer, and their Enphase system package was top-notch. There was a small hiccup with the system reading the input and output correctly, but even though their team was super busy over the summer, Anahi, Dre, and Ben carved out time to get my system working perfectly. Big shoutout to them for making it all happen! Highly recommend their expertise and customer service!

We decided to have solar installed at our house recently in the Central Valley, and went with United Solar Electric, given their strong reputation. We could not have been happier with the entire process. From the sales team, to the design team, to the installation group, they were all extremely professional and did a great job at communicating every step of the way. They also did a great job of educating me on how the system worked and what to expect, which was great considering I knew absolutely nothing about solar at the time. The installation of the panel assembly as well as the battery system was done very clean, and the system is working precisely as intended. I would highly recommend this company if you are considering solar!

When deciding to go solar, we first did a bit of research - online, speaking with neighbors, looking at reviews - before reaching out to solar providers for bids. Some got back to us immediately, some never did. Even the better-known providers were less than responsive, initially or going forward. We ultimately went with United Solar Electric. They were: • Responsive • Knowledgeable • Straight forward • Easy to work with • More cost effective with the best products and features Staff and crew were outstanding; Ben Vanni at the beginning and through it all, office staff (Anahi), installation crews (sorry, I don’t remember names), and ultimately Dominique, who followed through to the very end, staying long shifts, answering questions and helping us understand the process every step of the way. Excellent customer service at every turn, not always part of today’s business strategy. The entire process took a few months due to coordination between various entities – installation, permits, city approval, PG & E interaction – but in the end, we are very happy with the outcome. And in just a few days, our PG & E usage is way down. So glad we went with United Solar Electric.

An excellent company from every aspect. Provides a thorough customer service. Ben, who I dealt with is extremely knowledgeable and very pleasant to communicate.

United Solar Electric - Brentwood, CA.

I cannot speak highly enough about the incredible service and expertise provided by United Solar Electric! From the initial consultation to the final installation, every step of the process was seamless and professional. Firstly, the consultation was comprehensive and informative. Ben took the time to understand my energy needs and provided clear explanations of the available solar options, including the benefits and cost savings. They were patient and answered all my questions, ensuring I felt confident in my decision. The installation itself was nothing short of exceptional. The technicians arrived promptly and worked diligently to install the solar panels with precision and care. They demonstrated expertise and attention to detail, ensuring that everything was installed correctly and efficiently. Overall, I am thrilled with my experience with United Solar Electric and would highly recommend them to anyone considering solar installation. Thank you for helping me transition to clean, renewable energy while saving money in the process!

Solar + Batteries + EV Charger + SubPanel Upgrade

We had a more complicated install versus just a simple solar. We also had backup batteries, an EV charger and a subpanel upgrade. Most of the products are made by SolarEdge. United Solar did it all for us and the end result is amazing. The system has not given any problems and the install is very clean and neat. The city gave us such a hard time with the battery install, but United Solar kept working with them to ensure inspection was good. When support is needed, they are there to assist us. Special shout out to Ben, who was always there along the way, happy to help with any part of the project. He's been very supportive and very responsive for all needs we had. Thank you!

Our Solar Project

Excelent company that delivered on all aspects, as promised . The solar panels installed , even now in winter have produced enough to cover our electrical consumption of our 5 bedroom home . The products used are first class and from reputable companies . Highly recommended if you think Solar .

Patience, guidance, great execution

We had a few twists and turns on our project. We live in the hills so daylight was limited by trees. Our plan to install on our hillside was derailed by a landslide but this was compensated for by the loss of two big trees. And finally, our roof needed to be replaced. Throughout all of this Ben and the team and United Solar stuck with us, making sure we got our application for Nem 2 in before the deadline, then coordinating with our roofing contractor to get the jacks installed and sealed with the new roof. The installation teams did a great, professional job, and the electrical tie-in is very well labelled and tidy. My two engineering friends were quite impressed. In the ratings, I gave 4 stars versus 5 only because the site survey missed the fact that we have a foam-insulated roof. This ended up costing additional solar and roofing dollars, money well spent on a high quality job.

United solar delivers!

It seemed every Solar company sells you on the idea that seems too good to be true, but going through the entire solar process with Holly, Taide, and Ryan at United Solar, I must admit they delivered on everything they promised. They were professional and extremely easy to work with and kept me up to date on any changes or updates. They were responsive to emails, phone calls, and were exactly on time or early for each scheduled appointment. Their installation team were friendly and took extra precaution not to damage anything and cleaned up after their work was done. The whole process was fast and easy to do, unlike the rest of the construction projects I have had my house. I have and will recommend United Solar to family and friends, and would recommend them to anyone.

Standout service in a sea of solar providers

Had an excellent experience working with United Solar Electric. We reached out to various solar companies, listened in on many presentations, and ended up choosing them as they were the only solar company out of them all that was willing to go the extra mile in assisting me with my unique situation. I had pool solar panels that needed to be moved and the United Solar Sales Rep (Jedith) was the only one that was willing to help me find contacts that could help me with this. This level of service impressed me as all other solar companies said I was on my own to deal with it. Throughout the process, they were on time, knowledgeable, and always courteous. They followed up on some issues promptly, even during the holidays. I highly recommend working with United Solar if you're looking for a company that truly wants to provide the best service in the industry.

Was looking to get solar and had a couple bids with a few companies. United solar really impressed me. With the fast response time and customer service I was sold. They did a great job explaining how the process works and breaking down the steps. Also worked with me on locating the panels as I didn't have much rooftop space to work with. Did a really clean install trying to hide as much conduit as possible. Employees were really engaging and helpful when I had questions during the install. After was explained in detail what to expect, how to get the rebate and a timeline on when PGE would most likely turn the solar on. Great experience overall!!

Great Service

Ben was my sales man and was very responsive to any questions that I had and made sure everything went smoothly. They got their team out super quickly and they did a great job on the work. Would 100% recommend to anyone.

My husband and I have been wanting to obtain solar for a while but just didn’t take the leap. We finally looked into a few places and came across United Solar Electric, we are so happy with our decision! Ryan and his team has provided excellent customer service- something you just don’t receive anymore from most companies. They took their time to throughly explain and educate us on all the benefits of having solar, the best equipment for our family/home size and estimated a projected amount of solar that would be produced. With not knowing much about solar, the experience and knowledge their team brought to us was extremely appreciated. United solar team was very communicative through the entire project from the front desk, installers and even after project check ins. We truly received a hand holding experience. Knowing we aren’t their only client but feeling like we were is everything. Overall we are extremely satisfied and very happy with our decision to move forward with solar from United Solar Electric. If you are looking for solar with a feeling of knowing you’ll be taken care of, United Solar is the place for you - they will not disappoint. We’ve already referred them to a few family members and will continue to do so. Thank you for everything United Solar!

Through my experience with the company I felt that they are well established as the prompt answering of phone and calling back was the first positive stuff. This made me go further in business with them . It’s was not a mistake doing business with them as they kept the timely promise to move the work dispite so stand back issues with SMUD. The work team which installed were very knowledgeable and neat in doing the job.

Great customer service!

I worked with United Solar on a custom solar system for my home, and I was so impressed with their hard work and detailed communication. They have top of the line products and quick install timelines. Highly recommend!

Professional installation and service

Ryan and united Solar Electric were extremely professional and on the ball throughout the whole solar installation process. They worked closely with my HOA to get through the approval process and get the job done quickly. We recently move into Discovery Bay and were shocked by the PGE bills we were receiving. Ryan was able to give us a quote on a 7.8kW system that was far less than what we were expecting. Everyone from the company has been friendly, on time, and professional. I highly recommend United Solar Electric if you are looking to install solar on your home in the Brentwood, Discovery Bay, Antioch area!

Competitive price, professional service and installation

We had quotes from 3 different solar installers for a 11 KW system, each had the same inverter with different solar panels and one had a unique installation. After reviewing the quotes and speaking with each rep., we decided to go with United Solar Electric because of the price and service. Ryan is very professional, answered all our questions on the material, installation, warranty, warranty process. The installation agreement was very clear and was explained to us very well. The installation was completed on schedule, and my home was left clean. I am very happy with United Solar Electric. Recommended.
