Solar ROI Calculator
Calculate your solar panel return on investment. Estimate payback period, savings, and ROI based on system cost, energy production, and electricity rates.
Step 1: Solar System Details
Understanding Solar ROI
Solar ROI measures the return on your solar panel investment over time. Factors include system cost, energy production, electricity rates, and available incentives. A typical solar panel system pays for itself in 6-12 years.
Step 2: Energy & Financial Details
About Solar Incentives
Many governments offer incentives, tax credits, and rebates for solar installations. These can significantly reduce your upfront costs and improve your ROI. Check local programs for available incentives.

Solar ROI Formula
ROI = (Lifetime Savings – Net System Cost) / Net System Cost × 100%
To calculate solar ROI: Subtract incentives from system cost to get net cost. Calculate annual savings (annual kWh production × electricity rate). Multiply by system lifespan to get lifetime savings. Then apply the ROI formula above. Payback period = Net System Cost / Annual Savings.
