Solar PPA Cost: How Rates Are Calculated & What NJ Homeowners Actually Pay

A New Jersey Solar Power Purchase Agreement (PPA) is a financing arrangement where an authorized solar developer installs, owns, and maintains solar panels on your residential roof with zero upfront equipment purchase. In exchange, the homeowner purchases the electricity generated by the system at a predetermined per-kilowatt-hour rate that is lower than standard local utility tariffs.

A solar PPA works by pairing a solar developer who finances, installs, and maintains rooftop panels with a homeowner who agrees to buy the generated power. The solar provider installs the system at zero upfront cost, interconnects with your local utility via net metering, and bills you monthly for the exact kilowatt-hours produced at a discounted contract rate.
