I don’t like the experience…
I don't like the experience I did have with this company
they help with the solar panels as well with the loan company they come and put the panels but never finish the project and never gibe the money to the right contractor they are playing with other people money and no one answer the phone calls or emails
so I highly recommend to all the people who just start the solar project with this company don't do it with this company keep looking for more safe options

These guys sold a solar…
These guys sold a solar system to my parents who are living pay check to pay check on Social Security and Disability. The solar system was never connected nor turned on. The system was installed in June of 2021, and since then my parents have been making payments on the solar panels as well as their electric bill. No one answers when I call their customer service, no one replies to my emails. The lady we who was responsive now has a Address not found auto-reply to her email. I'm not sure if this company went out of business since they have their headquarters in San Francisco, but make sales in Long Island NY.

They didn’t try to oversell me. The rep was professional and upfront. Workers showed up in a timely manner, my solar panels were placed nice and neat, and my roof looks great. Am glad for the positive experience, and give them A plus.

We found this provider to be easy to work with. They were far more knowledgeable about the battery backup that we wanted than all the others. They answered all our questions before, during, and after installation and we're very pleased with the resulting system. We would recommend it to everyone wanting to go solar.

For solar for our business,…
For solar for our business, we reached out to a few different solar companies in the area and were very surprised by the range in price. We liked them because of the ratings and called them up. The process was extremely clear. The proposal, planning, and installation - it was all quite fast and efficient. It was an A+ process and I would recommend this company to anyone wanting to go solar.
