Estimate the total installed cost of solar panels based on your electric bill and location.
⚠️ The 30% federal solar tax credit (Section 25D) expired December 31, 2025. These estimates reflect 2026 costs without that credit. State incentives may still apply. Always get 3+ quotes from licensed installers.
The average installed cost for residential solar in 2026 is $2.50–$3.40 per watt. A typical 7 kW system costs $17,500–$24,000 installed. The 30% federal tax credit that previously reduced costs significantly expired on December 31, 2025, meaning homeowners in 2026 pay the full system price without that offset.
| System Size | Avg Home Size | 2026 Cost Range |
|---|---|---|
| 4 kW | Small / low usage | $10,000–$13,600 |
| 6 kW | Average home | $15,000–$20,400 |
| 8 kW | Larger home | $20,000–$27,200 |
| 10 kW | Large / EV charging | $25,000–$34,000 |
| 12 kW | Very large + storage | $30,000–$40,800 |
Yes — for most homeowners. Electricity rates have risen sharply and solar panel costs have dropped over 70% in the past decade. Payback periods in sunny states like Texas, Florida, and Arizona still run 7–10 years. In high-rate states like California, Massachusetts, and Hawaii, payback can be 5–7 years. Many states also offer their own incentives and net metering programs that credit you for excess power sent to the grid.
Always get at least 3 quotes from licensed solar installers. Prices vary significantly by company, equipment brand, and region. Avoid signing with door-to-door salespeople on the spot — take time to compare. Ask each installer for a detailed quote showing system size, panel brand, inverter type, and warranty terms.
