Electrical reviews in San Jose, California

Had a great experience with TN solar. They were right on schedule, installed in a day and inspection completed in 10 days. Will recommend them highly.

The owner Nhi , is helpful and goes above and beyond, and her installer “Hristo Eatrada” is a real professional in the solar sector, be it micro inverter, hybrid ,on-grid or off grid or pure battery systems, Hristo has knowledge about everything. Within two days they completed my solar installation that too on a high slope tiled roof, its been 3 months now , my PG&E bill used to be in the range of 400-500 it has come down to just $30 now. They are well versed for all kinds of roofs and i bet you would never find any one more honest like TN solar, there is this SunRun, Solar-city… all of them would try to put you into a 30 yr loan, TN tells you the cost right away without any hidden costs… and I bet they are the most economical along with delivering the best of solar installation.

I had a fantastic and stress-free experience with TN Solar Services from start to finish. Nhi efficiently handled all the back-end documentation, while Sonny led the installation crew with expertise. The installation day went smoothly, the inspection passed on the first attempt, and the service was approved within just a few days. I couldn’t be happier with my decision to go with TN Solar!

Thank you TN Electrical and Solar Company for completing the Solar system installation at my church. I was referred by friend who also had a solar system installed by Nhi's company a couple of years ago. NT. Company did a wonderful job. The Solar system was completed on time as promised. The price was very competitive. No one could beat her price. Nhi was very honest and very up-front with the price. She only recommended what was needed when other companies tried to recommend something that We didn't actually need (which cost extra) We're very happy😀 with her company. We're now start saving 💰
I would recommend this company to my friends and relatives.

Very happy with the overall experience. Hanh and the crew were very professional, available to answer any question and mostly, very knowledgeable. The job was perfectly done and we got the city permit right the way. Highly recommended.

TN Solar did a great job of installing our solar and battery system. From the time we signed the agreement until the time the system was fully operational was four weeks, and it's worked great ever since. I have noticed a number of items along the way that indicate their attention to detail and quality, and I'm glad to have used them to install my system.
Later: We've now passed a year with the system, and it is still performing very well. I'm very happy we added solar and chose TN Electrical.

I installed solar for my new ADU and ended up hiring these guys. They are very professional and I have no hesitation working with them again. Super responsive and helpful, budget friendly, and nice people overall. Hanh was great at coordinating everything and Hristo who installed the system was helpful with any questions I had even after the install.

TN Electricalz did an outstanding job with our solar installation. The entire process was smooth, well-organized, and completed on time. The team was professional, efficient, and made sure every detail was handled with care—from permits to final inspection.

A special shoutout to Hanh, who was exceptional throughout the project. She was responsive, knowledgeable, and incredibly helpful in answering all our questions. Her clear communication and proactive follow-ups gave us a lot of confidence and peace of mind.

The system is up and running perfectly, and we’re already seeing the benefits. We truly appreciate the quality of work and customer service TN Electricalz provided. I highly recommend them to anyone considering going solar!

our experience with TN was great. They were very good with paper work to make the process very smooth. The installation was fast and firm. We saved a lot of waiting time to have the system installed. Highly recommend.

I had a great experience with TN Electrical and Solar for adding a battery to my existing solar panels. I have done a lot of research before choosing Francklin HW battery because its smart feathers and compatiblity to my existing Sunpower panels. FranklinHW referred me three of their best authorized installation companies, TN Electriicial & Solar is one of them. But I think TN is the best by my experience. They responsed quickly in a very professional manner. Their price is very reasonable,and competitive, and they finished my job within two weeks ( from signed contract to final inspection. ). I have also given this good feedbacks to FranklinHW - the battery manufacure. Keep your good jobs TN !

We are extremely satisfied with TN Electrical & Solar Service. Hanh and Sony are highly professional individuals who provide excellent service at a competitive price. To our surprise, the installation process was completed in just one day after signing the contract. The city inspection followed promptly, taking less than a week after the solar system was installed. Truly a great company to work with!

My advice to future customers is to consider installing at least 20% more panels than your current daily usage to better account for future needs.

We had a good experience doing business with TN Electrical and Solar Services. The team was very professional and prompt. Our solar system was installed a week after we called them. The owner personally came to see the inspector and checked out the completed installation. I am very happy with their work.

Exceptional experience with TN! They were recommended to me by a friend. Their team was direct with pricing and didn't waste time trying to oversell me on unnecessary upgrades. Throughout the entire process, Hanh was incredibly responsive and efficient, completing the installation exactly as promised. What impressed me most was their willingness to accommodate all my special requests without hesitation. No misleading sales tactics or grandiose promises - just straightforward, quality service from start to finish. Highly recommend to anyone looking for a good solar installation.

I’m a repeat client of this company, which previously installed my solar panel system. With the recent increase in outages, I decided to add two Powerwall batteries. Sonny and Nhi responded quickly to my inquiry and scheduled an inspection just a couple of days after my call. Within two weeks, the company ordered the parts and completed the installation. The technicians were fast, professional, and efficient. A week later, the city inspector came and approved the permit without issue. Overall, I highly recommend this company for all your electrical needs.

TN Electrical is hands down the best company I’ve worked with in the solar industry. While many solar companies are overwhelmed right now due to the rush before federal incentives expire—and often stop responding to customers—TN Electrical truly sets itself apart. No project is too small, and every customer is treated with care and urgency.

I reached out on August 10 to add one Tesla Powerwall and one expansion pack. To my surprise, the site assessment happened that very same day, the installation was completed within two weeks, and final inspection passed flawlessly on August 28. Start to finish, everything was done in just 18 days—remarkably fast compared to typical industry timelines.

Special thanks to Nhi and Sony, who went above and beyond to fit me into their tight schedule, even working on a Sunday to make it happen. Their team arrived on time, executed the installation flawlessly, and left the site spotless. The conduit runs are beautifully done—neat, precise, and professional.

What impressed me the most, though, was the communication. Both Nhi and Sony were consistently responsive to my texts and patient with every question I had. It’s rare to find this level of customer service in such a busy industry.

If you are considering solar or battery storage, I can’t recommend TN Electrical enough. They deliver exceptional quality, outstanding customer service, and unmatched speed in execution. Truly a 5-star experience from start to finish.

Highly recommend TN solar. I think they are very responsive to your questions (one can have several questions around solar installations) and Nhi was very patient in answering all my questions. From talking to them to installing everything was in 1-2 weeks. Also i think they have the best prices in town!

We hired TN Electrical and Solar service to install solar for our house. Their service is top notch, with excellence in quality and customer service. Bonnie was super fast and responsive via text and call, even when she was out of town on vacation:). Bonnie and Hristo were very knowledgable about solar options and provided great recommendations on what option is best for our house. They were able to install solar within the following week of signing contract. Since the installation of our solar system, we were able to dodge 3 power outrages lol. Thank you to TN team for your super fast and quality work. I would recommend them to anyone and in fact, I am going to use them again for another project in a couple months.

TN Electrical is an outstanding business. They are knowledgeable and very concerned to give their customers the optimum system for their needs. The installation was quick and very well done. My system has worked flawlessly. And the one time I need advice they responded immediately on a weekend! They also are very good at working with PGE to get your system approved. That in itself is a major task and they do everything. I HIGHLY recommend TN electrical. They are the best.

When considering solar panel and battery contractors, this review should be the last you ever need to read. If you do not choose TN electrical and solar services , then you have made a tremendous mistake.

I spent months reviewing and consulting contractors across the entire bay area for my 31 panel 2 battery project. TN solar and electric was multiple orders of magnitude better than any other contractor I consulted. TN solar and electric provided the best customer service experience and price. Hanh always provides the most up to date information and equipment for planning the project AND always emphasized ensuring the best value (aka most solar savings per dollar spent on the project) for the customer. Her installer Sony is detailed oriented and professional in his craft as an electrician. His team did an excellent job with both the solar panels and battery installation (see photos). My project could not have proceeded any better than I could have imagined.

I wholeheartedly recommend choosing Hanh and Sony, and I am happy to be a reference for them/their work.

TN Solar did an excellent job with the installation. This is our 2nd experience with them and they did not disappoint. They managed to squeeze us under the wire to get the 2025 rebate, even managed the permit and the inspection

I had TN to do our project for the ADU. They did such an amazing job with clean installation from roof into garage. The quote was a great price for installation of 14 panels. Once the contract was sign Hanh did a fantastic job keeping her word and time. She was able to fit us into her busy schedule and by the time 1 week after installation was finished. I was like "wow" this is fast. Overall I would recommend this solar company to anyone if they ask. Great Job and thank you for your service!
