Solar Energy System reviews in San Jose, California

Our experience with TN Solar was great. Very responsive all through quote/install/inspection. Easy to communicate with. Installation was super fast (20 days from my first email to passing city inspection), while other companies I talked to said "we hope we can install before end-of-year but can't promise". The work was exceptionally clean and the price was reasonable.
Proactively recommending this company to our neighbors and friends.

TN Electrical and Solar Services was a great service provider to help me add solar to my existing home. Hanh was a very helpful guide in providing advice on what system to use, while offering a comprehensive solution from scoping to final inspection with the city. Even when there was an issue with the inspection, Hanh and team worked diligently to have the problem fixed within 24 hours, and helped pass inspection for the system approval. Would recommend to others!

I hired TN to do our solar project, after getting 3 diff quotes, they were the best at communicating and had the best price. Once I signed the contract, they literally had the whole project done the same week. Super impressed with the work, Hristo from the team was amazing at the install and helped walk me through everything in the end. Definitely recommend them!

As a solar installer for the last 3 years I will say that the installers at TN pay close attention to detail, will go the extra mile to make sure the job is completed properly and also take the time to make sure it looks well done for everyone to see. I am very satisfied with the attention that is put into their work, they are great to work with, and they treat the employees and customers well.

I highly recommend TN Solar for residential solar installation. The entire process was seamless, professional, and remarkably quick.

From the start, Hanh was fantastic. She provided a transparent quote, clearly explained the system components (panels, inverter, etc.), and was extremely responsive to all my questions about energy production and paperwork. There were no hidden surprises, and the timeline she set was accurate.

The installation crew, led by Soni, demonstrated outstanding craftsmanship. They completed the work efficiently and, most importantly, the final installation is incredibly clean—all the conduit routing is neat and discreet, showing great attention to detail.

Our system is running perfectly, and we are already seeing the benefits on our first bill. If you want a trustworthy team that delivers on quality and customer service, ask for Hanh and Soni at TN Solar!
A true 5-star experience.

I had an excellent experience working with TN Electrical and Solar Services from start to finish. The team was knowledgeable, transparent, and patient in answering all my questions. They walked me through every step of the process — from site evaluation, to installation and system activation. The installation crew was professional, on time, and kept everything clean and organized. The panels look great, and the system has been performing exactly as promised. Overall, I’m extremely satisfied with both the service and the results.

We got the solar installation done in october 2025 - had 22 rec 460 panels, 2 powerwall 3, main electrical panel upgrade as well as electric car charger. Hanh and Sonny were patient and flexible with us through the whole process. We had to get a new electrician in the very beginning of the project which was a huge hassle but Hanh was there helping us navigate everything. She also helped us through the pge permit process. The panels and PW and car charger are all working flawlessly for well over 6 months now. Thank you TN solar!

TN did a great job installing the solar and Tesla battery for me. Nhi is so knowledgeable in answering all my questions. The price is great. Sony and team did the installation, so professional! Strongly recommended!
