The Bad

Only Available in New York

SUNation Energy only offers service in Nassau, Suffolk, Queens, and Long Island. Unfortunately, if you live outside of these regions, you won't have the option to do business with SUNation Energy.


The Bottom Line

SUNation Energy offers purchase to own payment options, as well as a number of different brands of high quality equipment, including LG, Panasonic, and Solaria panels. The company provides its customers with great warranties, but as of now, it only services a few areas in New York. If you live in one of those areas, SUNation Energy may be a good option for you. However, if you live elsewhere, you'll need to check out other solar companies.
