New Jersey’s Successor Solar Incentive (SuSI) Administratively Determined Incentive (ADI) program — commonly called SREC-II — provides Trenton solar homeowners with a fixed, guaranteed income stream for 15 years from the date of interconnection. For every 1,000 kilowatt-hours (1 megawatt-hour) of solar electricity your system produces, you earn one SREC-II valued at $85, paid by PSE&G as part of the utility’s renewable portfolio obligation. A typical Trenton system producing 10,000–12,000 kilowatt-hours annually generates 10–12 SREC-IIs per year, worth $850–$1,020 annually — income that arrives on top of net metering bill savings for the full 15-year term.
Unlike Pennsylvania’s open-market SRECs, which fluctuate with supply and demand and currently trade at $25–$50 per credit, New Jersey’s SREC-II rate is fixed at enrollment and does not change based on market conditions. This predictability allows precise long-term financial modeling — you know from day one what your SREC-II income will be through the end of the 15-year window. SREC-II income is taxable at the federal level as ordinary income; consult a tax professional about reporting requirements. The program requires your installer to register your system with New Jersey’s Clean Energy Program; confirm your installer handles this registration as part of the installation process. You must own your system to earn SREC-II credits — leases and PPAs transfer the credits to the third-party system owner.
PSE&G provides full 1:1 retail-rate net metering to Trenton residential solar customers under New Jersey’s net metering mandate. Every kilowatt-hour exported to PSE&G’s grid earns a credit at PSE&G’s current retail rate — approximately 26¢ per kilowatt-hour. Credits roll forward month-to-month and reconcile annually. New Jersey’s net metering framework has been stable and is supported by the New Jersey Board of Public Utilities; the 2022 legislative attempt to reduce net metering in Florida has no New Jersey parallel, and NJ’s BPU has actively supported solar expansion. New Jersey also provides a 100% property tax exemption on the added home value from solar and a full exemption from state sales tax on solar equipment — the most complete tax protection package in the Northeast alongside Massachusetts and Virginia.
One practical consideration for Trenton PSE&G customers: PSE&G interconnection timelines have extended in recent years as solar installation volumes increased across central New Jersey. Some Mercer County homeowners have experienced 4–6 month interconnection approval timelines — panels installed and waiting on PSE&G’s approval before the system can activate and begin producing credits. Choose an installer with direct PSE&G interconnection experience in Mercer County and ask specifically about current interconnection queue times at the time of proposal. The delay does not affect the system’s eventual economics but does push back the start of payback.
New Jersey solar installations run approximately $2.70–$3.20 per watt in 2026. Central New Jersey’s competitive installer market — serving the Trenton-Princeton-Hamilton corridor — produces pricing within this range. A typical Trenton system of 7kW–10kW costs approximately $18,900–$32,000 before incentives. New Jersey’s 100% sales tax exemption saves approximately $1,133–$1,920. The 100% property tax exemption prevents Mercer County property tax increases from the installation. No federal residential ITC applies to 2026 cash or loan purchases. At PSE&G’s 26¢ rate and with SREC-II income of $850–$1,020 annually for a typical system, combined annual solar value runs approximately $2,600–$3,500. Cash-purchase payback for Trenton systems runs approximately 7–10 years — among the faster mid-Atlantic outcomes — with 25-year savings estimates in the $40,000–$65,000 range depending on system size and rate trajectory.
