Is solar worth it in Indiana?
It depends on your bill, roof and utility rules. Here is an estimate for a home with a $150 monthly electric bill and a south-facing, unshaded roof, before any incentives:
- Residential electricity averaged an estimated 17.04¢/kWh in Indiana (January–July 2026), below the U.S. average of 18.19¢ (20 of 51, highest first). Source: EIA Electric Power Monthly, Table 5.6.B (accessed 2026-10-20)
- Small rooftop systems in Indiana produced an estimated 1,522 kWh per kW of panels in 2024 (2024 small-scale solar generation divided by average 2023–2024 small-scale capacity). Source: EIA Electric Power Annual 2024, Tables 3.21 and 4.7.B (accessed 2026-10-20)
- Estimated system size: 5.1–6.9 kW, producing about 9,132 kWh a year (estimated).
- Estimated installed cost: $18,000–$31,200 before incentives, using $3.00–$5.20 per watt. Source: Lawrence Berkeley National Laboratory (2024 installed prices, 20th–80th percentile; accessed 2026-10-20)
- Estimated simple payback: 10–24 years. Savings depend on how your utility credits exported energy (see above).
