Palmetto Reviews
Palmetto has been great! Every step of the process was a lot easier than I initially thought it would be. Stacy was very knowledgeable when it came to breaking down how everything worked. The install was quick and the panels work just as advertised. Happy with everything so far.

Im very happy with my solar panels. My experience from the beginning until the installation was amazing. All the representatives of Palmetto were detailed in explaining the entire process to me.

I had priced solar at 3 other companies and those companies prices were too high! Palmetto was able to get me solar with no money out of pocket and now my electric and solar bill combined are cheaper than my electric was before solar! Electric prices are only going to continue to rise and I’ll be locked in to the cheaper same amount for 25 years! Thanks Palmetto!
