SolarUnion

I wish I could give less than one. Seldom gave bad review at all as I usually suck it up. I admit some of the problems might have caused by the delay of my own construction crews. But then the back and forth when somethings went long took very long time to resolve. Totally blindsided that a heat detector interconnect to a smoke alarm inside the house is required by the building code for the solar battery in the garage (ESS) in California. It would be very easy to take care during the construction to add the extra wiring. Now they said we need to pay for everything. The lack of professionalisms really shocked me. I picked them because thinking they are local and in-town but actually the project management is offshore. This is something you need to watch out if things goes south.

After many interview and getting so many quotes from many vendors, my wife and I decide to go with SolarUnion to embark on our solar power journey. And it was definitely the right choice. We didn't know anything about Solar power or solar energy. But we learn so much along with SolarUnion. Everything was done professionally and timely. From the beginning, where they did the drone survey, the proposal and contracting, and iterating with us on the design and, and finally the installation and inspection, everything is nothing less than perfect. The thing we value most is their responsiveness. They always get back to us whenever we any question for them. The workmanship of the installer was superb. Not only do they work well, they also look very good. It's almost like a piece of well designed work of art. I must say that I highly recommend SolarUnion for anyone who is embarking on their Solar Power Journey.

Update: If you need to transfer ownership, go to Solaredge web page "Request for Monitoring Site Transfer and New User Access", I've been asking how to change ownership for so long and no one in SolarUnion answered my questions, now I found the answer myself. Paid $99 dollars, and the site transferred to next owner (sold my house). Previous reviews: After seeing Picky Engineer's review, I'm confident that SolarUnion is the perfect choice for my OCD family's solar panel installation needs. & Thank you for all your review, it helps through when I have doubt but later your review, the staff name you mentioned in your review help me rebuild my confidence. My project started March and my NEM 2 & design approved at end of September. ( No complaints, I know lots of people want NEM2) I've been contacted by so many staff member. But Gelica is the one always respond my email. Andrei & his team , the contractors, his name been mentioned several occasions in the review already I know I am in good hand. Mary : is difficult to look for using email, but she responds text so fast, she's the one respond for schedules also after installation steps ( registration & apps download) & another schedules for inspections. & I love almost every single staff I ever talk to including my sales representative So far, I love my solar installation, I feel like I cheat a bit by selecting the company is a bit more expensive because I want quality work, and now I love every penny I spent. Update : after using 4 months, there's several storms in the winter, and Feb 4, 2024 we had a power outage from PG&E , and my solar just switch immediately, I get to invite my neighbor over for a warm dinner, that is awesome. Highly recommend it.

SolarUnion installed a 6 KWh system with battery backup in East Bay for us under NEM 3.0. The whole process took about 6 months. They took care of designing system, getting permits with city, working with PGE, and getting everything connected. The installers were excellent and also installed the EV charger and changed the house main panel to upgrade electrical service to 200 AMP. They respected the contract terms and I expect them to be around for the 10 year battery warranty and 25 year solar panel warranty in case anything fails. I have been very happy with the system and power consumption from the grid is at 10% of previous levels and I never pay high TOU rates at night anymore. Also, we just had our most recent PGE power shutoff a few das ago and the backup system worked flawlessly. The whole house kept on working after a few seconds delay and we went on about our day.

Loved the way they respected the COVID threat. They wore masks and where very professional in the way they handled this tough situation. After reviewing two other solar companies, I chose them based on their high Yelp rating and because every single person I talked was genuinely interested in me and in my project. The equipment they installed is rated as the best on the Market and the components were engineered to give the best performance over the life of the Solar Panels. I can watch my solar production from an app. My solar production is also reported back to Solar Union for them to use in evaluating the production. The warranty was also a great selling point. If you are shopping solar companies make sure you compare warranty info We passed our county inspection with no issues to be resolved. That was a big relief. Great company. Loved working with them.

Solar Union was great to work with. I had a complicated install job, Roof was being replaced, I wanted the roofers to waterproof the solar panel supports which required Solar Union to come out on the day my roofer was present and come back after the roof was completed to continue the installation. No problems at all. Recommended to friends and they got their system.

Solar Union did a good job on the overall new solar project on our house in San Francisco. I would definitely recommend. The panels have been operating flawlessly for almost a year now. They were a bit more expensive than other quotes but they are a large enough company with different businesses and I expect will be around to fulfill their 25 year warranty. They also recommended a roofer who was able to meet the timeline and provided a very competitive quote. It took a few times back and forth of reviewing the plans and providing feedback because the engineers doing the layout couldn't initially figure out how to fit the panels in the planned space from the original quote. I ended up going up on the roof to collect more exact measurements, looking up the code myself to explain how what we originally planned will still meet code requirements, and providing a sketch. Additionally the drawing had a couple errors with the electrical panel and inverter at the wrong end of the house and incorrect, undersized inverter model. I would rather they had been able to get this right without my help but getting all the details right is really tricky and I would expect this of every solar installer. After this was all squared away I didn't hear anything for a few weeks, which was expected since construction start was planned quite a few weeks away, then got an update, and nothing for 4 more weeks until a call saying they will arrive the next day to do the install! A little more advance notice would have been nice, but the date and time worked fine. Installation went great, completed in about 2 days. The installers were really knowledgable. They followed the plan, called in to discuss changes that were missed in order to meet code and tweaked accordingly. I worked in residential construction for many years and I checked their work on wiring and waterproofing and it was all high quality work. The inspection was smooth - only concern was they used flex conduit in the basement for a long run instead of rigid, but the inspector let it pass. From first phone call to getting PG&E permission to operate and enabling the inverter was a bit more than 6 months which was quite a bit longer than the 3-4 months quoted, but still reasonable.
