A note on the federal tax credit
The federal residential clean energy credit (25D) doesn't apply to expenditures made after December 31, 2025. The IRS treats an expenditure as made when installation is completed.

Is solar worth it in Mississippi?
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 15.19¢/kWh in Mississippi (January–July 2026), below the U.S. average of 18.19¢ (33 of 51, highest first). Source: EIA Electric Power Monthly, Table 5.6.B (accessed 2026-10-20)
- Small rooftop systems in Mississippi produced an estimated 1,829 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 10,974 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)
