About This Tool
This quick estimate uses your state's average residential electricity rate (EIA Electric Power Monthly, March 2026) and average peak sun hours (NREL NSRDB) to estimate how much solar could save you each month. Installed cost is estimated at $3,000/kW, based on the NREL 2024 Residential Solar Cost Benchmark.
This tool is intentionally simple. If you already have a quote from an installer, use the Residential Solar ROI Calculator for a more precise analysis with your actual system size, cost, and local electricity rate.
Federal tax credit notice: The 30% residential solar tax credit (Section 25D) expired December 31, 2025 under the One Big Beautiful Bill Act. This estimate reflects pre-incentive costs. State incentives remain active — check your state's programs for available credits and rebates.
