How the Solar Savings Calculator Works
Our calculator uses your monthly electric bill, state location, and roof orientation to estimate system size, cost, and savings. We factor in the 30% federal tax credit, state incentives, local electricity rates, and solar irradiance data to provide accurate projections.
Key Inputs for Accurate Estimates
Enter your average monthly electric bill, state, and whether you own your home. For more precise results, provide your roof orientation (south-facing is ideal) and any significant shading. These factors can impact savings estimates by 15-30%.
Understanding Your Results
Your results include estimated system size, installation cost before and after incentives, monthly savings, payback period, and 25-year total savings. We also show which financing options are available and how they affect your monthly cash flow.
