A real cost breakdown for a typical 6kW system in Pennsylvania, not just a national $/watt figure.
Pennsylvania has a fairly typical electricity rate nationally at approximately $0.16/kWh, and a solid, average solar resource at 4.0 peak sun hours a day. Combined with a regional installed-cost estimate of $2.80/watt, a standard 6kW residential system runs approximately $14,630 before any incentives.
| Line item | Estimated cost | Share of total |
|---|---|---|
| Equipment (panels, inverter, racking) | $9,240 | 63% |
| Labor / installation | $5,040 | 34% |
| Permitting & inspection | $350 | 2% |
| Total (before incentives) | $14,630 | 100% |
A 6kW system in Pennsylvania costs 14% less than the average across the 25 states we track ($17,060), and the electricity rate it offsets is roughly in line with the 0.16 USD/kWh average across those same states. That combination is what actually determines whether Pennsylvania is a faster- or slower-than-average place to go solar — a lower system cost alone doesn't help if the rate you're offsetting is also low, and vice versa. See how every state stacks up on the Electricity & Solar Rate Tracker.
At $1,121 in estimated annual value from 7,008 kWh of yearly production, this system pays back in roughly 13 years — a longer payback period than the national average. Pennsylvania: Statewide net metering at retail rate. On incentives specifically: Pennsylvania runs an SREC market (Solar Renewable Energy Certificates) that pays an ongoing amount per MWh produced. The federal residential tax credit (Section 25D) expired for owned systems after December 31, 2025 — see our 2026 tax credit guide for what that means for your net price.
A typical 6kW residential solar system in Pennsylvania costs approximately $14,630 installed in 2026, based on a regional estimate of $2.44/watt — equipment usually makes up about 55% of that, labor about 30%, with the rest in permitting.
At Pennsylvania's average rate of $0.16/kWh, a 6kW system pays back in roughly 13 years — a longer payback period than the national average. Your actual number depends on your usage and roof; check it precisely with the Solar Panel Cost Calculator.
A 6kW system in Pennsylvania costs 14% less than the 25-state average of $17,060, while the electricity rate it offsets is roughly in line with the 0.16 USD/kWh average across those states.
