Is solar worth it in New Hampshire?
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 26.79¢/kWh in New Hampshire (January–July 2026), above the U.S. average of 18.19¢ (9 of 51, highest first). Source: EIA Electric Power Monthly, Table 5.6.B (accessed 2026-10-20)
- Small rooftop systems in New Hampshire produced an estimated 1,435 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: 3.4–4.6 kW, producing about 5,740 kWh a year (estimated).
- Estimated installed cost: $12,000–$20,800 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: 7–16 years. Savings depend on how your utility credits exported energy (see above).
