Pennsylvania vs New Jersey Solar Incentives: Which State Gets the Better Deal?
Side-by-side comparison of Pennsylvania and New Jersey solar incentive programs in 2026: state tax credits, net metering rules, exemptions, payback period, and projected 25-year savings.
| Metric | PA · Pennsylvania | NJ · New Jersey |
|---|---|---|
| Avg Monthly Bill | $145 | $165 |
| Peak Sun Hours / Day | 4.3 | 4.4 ◆ |
| Avg $/Watt Installed | $2.9 ◆ | $2.95 |
| State Tax Credit | None | None |
| Net Metering | retail | modified |
| SREC Market | ~$7400 | ~$15400 |
| Property Tax Exempt | No | Yes |
| Sales Tax Exempt | No | Yes |
| Payback, pre-credit model (yrs) | 8 | 6.5 ◆ |
| 25-yr savings, pre-credit model | $36,400 | $54,700 ◆ |

State Tax Credit Comparison
Pennsylvania offers no state income tax credit. New Jersey offers no state income tax credit.
Net Metering Policies
Pennsylvania: retail rate net metering active. New Jersey: modified 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
Pennsylvania: $36,400 over 25 years (avg payback 8 yrs). New Jersey: $54,700 over 25 years (avg payback 6.5 yrs).
Verdict: Which State Wins on Solar?
New Jersey delivers stronger lifetime solar economics than Pennsylvania due to higher solar irradiance.
