SolarUnion - San Francisco, California

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.

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.

We were very pleased with the installation and are very much enjoying having a mini-solar plant on our roof. It's a big job to do all the design, the permits, the install, and the interconnection. Nice work all around Solar Union!

We signed a contract for the installation of solar panels with SolarUnion in March/April 2023. In July 2024, we received an email with a unilateral cancellation of our contract. We had to contact them to determine what happened. Per their admissions on phone and email, they failed to submit our permit application and so they also failed to secure the NEM 2.0 rate, which is more favorable than the NEM 3.0 rate. Per their email: "I am sorry to be the bearer of bad news, but after conferring with all pertinent parties I regret to inform you that your site has not secured net metering 2.0 status." "The permitting team did not submit the application for your site as a result of an oversight in the submission process unfortunately. There is no way around it. Anything that we do at this point to install a system that you own would be under NEM 3.0." We asked for a discount for continuing the work since we lost the favorable rate and therefore lost money, but they refused.

Update - I am still waiting for a transformer upgrade and we're at over a year and a half since the install, and PG&E is saying it won't be until April 2025, nearly 2 years since I first started this project.
SolarUnion also came out after I had to figure out there is a way to potentially use the SolarEdge inverter to limit the amount of power going out to the grid (supposedly this is supposed to work). Goes to show they don't even know how their systems work. That was September 2024, and I still have not seen any sort of reduction in my solar bill, so that's probably not even working now. Who know's if the system even works that they installed. Stay away from these people.

While the sales and install process was straightforward, after-sales service is *extremely* disappointing.

We have had our system for approximately 2 years and recently it shut down after detecting a ground fault. When contacted for help, SolarUnion insisted on advance payment of $1,000 for a service call to be scheduled, and refused to consider whether the fault could be due to workmanship and therefore covered under warranty.

I had to chase them to schedule after payment and received an appointment almost 3 weeks later. Now, after waiting at home for service techs to arrive, I'm advised that the appointment was postponed for another week (the communication I received implied it was just a different time during the same day).

Every day of delay is costing us money in addition to the cost of the service visit we had already had to front. I'm very disappointed in Solar Union's follow-up and professionalism.

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.
