Your real number depends heavily on your actual usage and roof — run it precisely in the Solar Panel Calculator, pre-loaded with New Jersey's defaults.
New Jersey: Statewide net metering at retail rate plus SREC-II incentive. That's roughly a 100% export credit relative to the retail rate in our model — see the exact math for your own production and consumption in the Net Metering Calculator.
The federal residential tax credit (Section 25D) expired for owned systems installed after December 31, 2025 — see our 2026 federal tax credit guide for the full picture. At the state level: New Jersey's SREC-II (Successor Solar Incentive) program is one of the strongest ongoing state incentive structures in the US. Check the Solar Tax Credit & Incentive Calculator for a worked example, and verify current program status with a database like DSIRE before budgeting around any specific number.
