A real cost breakdown for a typical 6kW system in Indiana, not just a national $/watt figure.
Indiana has a fairly typical electricity rate nationally at approximately $0.15/kWh, and a solid, average solar resource at 4.1 peak sun hours a day. Combined with a regional installed-cost estimate of $2.70/watt, a standard 6kW residential system runs approximately $16,200 before any incentives.
| Line item | Estimated cost | Share of total |
|---|---|---|
| Equipment (panels, inverter, racking) | $8,910 | 55% |
| Labor / installation | $4,860 | 30% |
| Permitting & inspection | $2,430 | 15% |
| Total (before incentives) | $16,200 | 100% |
A 6kW system in Indiana costs 4% less than the average across the 50 states we track ($16,872), and the electricity rate it offsets is 7% lower than the 0.16 USD/kWh average across those same states. That combination is what actually determines whether Indiana 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.

At $1,077 in estimated annual value from 7,183 kWh of yearly production, this system pays back in roughly 15 years — a longer payback period than the national average. Indiana: Net metering being phased down to a lower excess-credit rate by utility. On incentives specifically: Indiana's net metering excess-credit rate has been declining for newer systems — check your specific utility's current rate. 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 Indiana costs approximately $16,200 installed in 2026, based on a regional estimate of $2.70/watt — equipment usually makes up about 55% of that, labor about 30%, with the rest in permitting.
At Indiana's average rate of $0.15/kWh, a 6kW system pays back in roughly 15 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 Indiana costs 4% less than the 50-state average of $16,872, while the electricity rate it offsets is 7% lower than the 0.16 USD/kWh average across those states.
