Palmetto Reviews
Having Palmetto install solar panels to my house was seamless, new subsidized roof, trimming of trees to get more production… should have done it years ago!
- Keith Guyer, Grafton, Massachusetts
I am very happy with my solar installation. Since installing it I have gotten almost $8000 back from the federal government in tax rebate, several hundred dollars from my local utility–a benefit that lasts for ten years–and I have paid absolutely nothing to my utility–and I currently have a credit of over $200, that should get me thru the beginning of winter when solar production is down. My bill has gone from over $2500 per year to zero. I was especially happy that my system seems to be putting out a bit more than was estimated. The Palmetto techs were very cooperative and explained every step of the installation.
