Why Princeton Homeowners Are Going Solar in 2026

If you’re a homeowner in Princeton, Mercer County, there’s never been a better time to go solar. Electricity rates from PSE&G have been climbing — the current average is 18.48¢ per kWh, and most Princeton households pay around $200/month. That’s money going to the utility with nothing to show for it.

A typical Princeton home needs a 12 kW system to offset most electricity usage. Over 25 years, that’s estimated savings of $58,000+ — before the 30% Federal Tax Credit (~$12,500 back).
