How Indiana compares to the rest of the US
Two numbers drive solar economics: your electricity rate and how much sun your roof gets. Here's where Indiana stands against the national average.
| Electricity rate | $0.15/kWh (10% lower than the $0.17 US avg) |
| Daily peak sun hours | 4 (10% less than the 4.5 US avg) |
| Net metering | Limited / utility-specific |
Indiana has both below-average electricity prices and below-average sun, so the payback runs longer than in top solar states. Solar can still be worthwhile — especially if your bill is high or rates keep climbing — but it pays to compare a couple of quotes carefully here.
