Solar in Trenton: What Homeowners Should Know
Trenton sees an average of 4.4 peak sun hours per day, which is what ultimately determines how much electricity a rooftop system produces here. A standard 8 kW system (about 20 panels) generates roughly 10,278 kWh each year in Trenton — and paired with New Jersey's local electricity rate of $0.186/kWh, that's where the savings come from.
At those numbers, a Trenton homeowner saves about $159/month ($1,912/year). Against a $25,600 system cost (about $23,600 after New Jersey state incentives), that works out to a payback of about 12.3 years, after which the system produces essentially free power for two decades — an estimated $41,702 in lifetime savings. Note: the 30% federal tax credit expired at the end of 2025 for purchased systems, though a solar lease or PPA can still pass it through. The local grid is served by Jersey Central Power, whose net metering policy directly affects how much credit you earn for surplus power.
