Palmetto Reviews
The consultation was top notch the whole way, even after the install. At times companies will treat you like royalty before you put down the signature, but then drop off afterwards. But Palmetto Solar was professional along the whole way. I already recommended them to neighbors.

Palmetto Solar was open and honest throughout our domestic installation process. Communication at all levels from team members was consistent and professional. I would recommend them to anyone.

Loving our solar and the savings we’ve already seen. The first month’s electric bill was at least $150 less than what we were paying. I’ll be interested to see what this month brings since we finally started using the air conditioning. Just so you know, I’ve been recommending y’all to people who ask.
