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. read more

We are pleased with the quality of work provided by TN Electrical and would confidently recommend them.

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! read more

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, 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. 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. read more

Sorry to have to change my review. But after couple months to have my solar system, their customer service is not as good as before. I have my problem with my power wall while it tried to drain out itself even after the sun goes down. I tried to contact Sony and he said this is the calibration process so it should be like that. But I experienced the calibration process before, it should put my battery as standby mode without draining and it should show Calibration Processing on Tesla app. This problem happened after PGE came to my house so I would like him stop by and check to make sure everything good before I contact Tesla. But he refused to come On the installation day, his team drilled the outside wall to mount the batteries and damaged my inside wall. I complained him and he said this is possible because not 100% to find the studs. Im like did you mention that before drilling, let see how your customer would say Please be aware to go with this company, before and after the money should be different read more

I have a great experience working with Nhi and Duong. Their price is the best among those I quote with (including Costco Sunrun and Tesla), and they are very fast in both communication and installation. After installation, they told me there was 2 cells that were broken and they replaced it for free, even though I wouldn't have known if they didn't tell me. Love the honesty! Highly recommend TN! read more

Knowing TN from a friend and TN installed my solar 2 years ago. It was great experience: prompt response, great price, quick design, permit, high quality installation. TN was able to secure LG panel for me per my request even it was hard to find it at that time as LG decided to go out of solar panel business awhile before that. I have recommended TN to a few friends and they used TN as well with great feedback. read more

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! read more

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 ! read more

it is ok, at very beginning was good, had proposal and info. looks know how to do with Metal roof, later giving out suggestion for adding 25 panle more based on a tesla car, e-water heater and a sauna unti with 1800w. which is not close to the right info. i dont know if they know what to do....1st, for the house with 14 panel already no way to adding 25 panels more ??? 2nd, it is not the right info compared with other proposal.... read more

It have been two years since we have our solar install. I purposely waited to get through two rainy season before putting up this long overdue review. I wanted to get our solar install to offset the cost of our ever growing family of EV. I reached out to several well-known companies (SR, SP, T). All of whom either refuse to work on my tile roof or gave us ridiculous go-away rates. One of my friend who recently got his install through TN introduced them to me. I was able to get an appointment for them to come out within the same week. Upon reviewing my current and future power need, they were able to put together a reasonable proposal. It was not the cheapest in the market, but it was definitely the best value. I got the best panels, inverters, and service. The insulation took two days because the crew selected the most optimal cloudy day to minimize tile damage. Overall, only 6 tiles was broken. Our inspector arrive the next day and marvel at the high quality routing and installation the crew performed. It's actually pretty amazing, considering this was at the peak of Covid when supply chain was a major issue and government officials were playing hookies at home. Well, now we are up to today. Even with 12 atmospheric river running through California there not a single leak in my house. The panels are still running flawlessly producing plenty of energy, 12MWh annually Over the last several years, I've seen this company grown both in size and reputation. I have no hesitation in recommending TN for your electrical and solar needs. read more

Fast service reliable and quick response On time I love to recommend this to friends and family read more

Installed solar panels and 2 Tesla powerwall 3 units. A very prompt response (once you call them) and a high quality (clean and neat with panels and conduits. Went extra length to hide conduits in the crawl space) installation within 10 days (much sooner than others). Moreover, the price is unbeatable, way lower than other contractors. Took care of everything, city permit and PG&E PTO. read more

What an amazing experience from A to Z! Customer service and satisfaction at its finest! At first I was a bit skeptical of solar as I had horrible experiences with other companies. But not with TN! Hahn Ni far exceeded my expectations. She walked me through the whole process step by step and kept every promise! I will definitely recommend this company to all of my neighbors! Thank you so much for restoring my faith in Solar and in Customer Service! read more

Absolutely recommend this company for solar and battery installation. Professional and efficient to work with.

Hanh provides swift and reliable services from start to finish, not shy putting efforts to go the extra mile. The quote she provided was competitive and perfectly tailored to my needs without trying to oversale. She educated me to better understand what solar was and was not, her advices were as well invaluable in the process to understand the various quotes I received from the competition. Her crew was personable and knowledgeable, showed up on time and performed the job flawlessly, including painting the conduits to match the exterior walls color. I installed the app to monitor the production from the system, export to and import from the grid: the savings on my huge PG&E bills were already up and running, easy to screenshot to share with my friends. Good job!! read more

I highly recommend TN Electrical and solar services! Duong did a great job. Nhi and her team are quick to respond, honest and easy to work with. They work efficiently together, listen to your concerns, and are very understanding clients, which I feel very important. The price is very reasonable and if you like to do your solar project, you should call them and compare. Thank you Nhi and Duong. read more

Excellent service and prompt response. My home is a 2 story Shapell home and they have no problem getting the solar panels up and installed in one day. The VP and sale rep are responsive and kept us informed with the delivery, installation, permit, and PTO, etc. The price is very reasonable comparing to another company which required us to upgrade the electrical panel and replace the roof. Also their electrician is great, knowledgeable, nice and helpful. He went out of his way to make sure there's no leak elsewhere on my roof and patched some of the cracks on my roof tiles. Really appreciate that. Overall I'm a happy customer. read more

Before calling TN Electrical and Solarl, i have inquired quotes from a couple solar company, big and small. I reached out to HanhNhi. She was very responsive, answered all my questions.

She continue to update us with the progress. I enjoyed working with TN Electrical and Solar. read more

They Did a great Job from Start to Finish. No issues through the whole process and had a great and fair price point.

Very pleased with the services level TN electrical & Solar provided. Top notch. Time from initial contact to installation is only 2 weeks.

We were able to compared price from TN v.s other solar companies. TN was the cheapest with top quality products : LG 380 panels and Enphase IQ8 microinverters and combiner box. read more
