There is a cost of $0.36 per day to stay connected to PSEGLI regardless of whether you power your home with SUNation solar panels or not. Con Edison’s basic service charge is around $16.00 per month. We can custom design a solar system for you that produces up to 110% of your previous year’s annual electrical consumption. If your system overproduces and you apply those credits to that basic service charge, yes, your final annual bill can absolutely be negative. And yes, PSEGLI or Con Ed may, in fact, send you a check in the end.
