State Tax Credit Comparison
New Jersey offers no state income tax credit. Pennsylvania offers no state income tax credit.
Net Metering Policies
New Jersey: modified rate net metering active. Pennsylvania: retail rate net metering active.
Net metering is often the most economically significant solar policy because it determines how excess production is valued. Retail-rate states (where you receive full retail price for exported energy) have substantially better solar economics than avoided-cost or no-net-metering states.
Average 25-Year Savings
New Jersey: $54,700 over 25 years (avg payback 6.5 yrs). Pennsylvania: $36,400 over 25 years (avg payback 8 yrs).
Verdict: Which State Wins on Solar?
New Jersey edges out Pennsylvania on lifetime savings primarily due to higher solar irradiance.
