Solar Panel Savings Calculator

Most U.S. homeowners save between $24,000 and $64,000 over 25 years, depending on their state’s electricity rates and sun exposure. Use the calculator above with your actual monthly bill for a personalized estimate.

A strong residential solar ROI typically falls between 200% and 400% over the system’s 25-year lifespan, with a payback period of 7 to 10 years being average across the U.S.

Yes. The 30% federal tax credit applies whether you pay cash or use a solar loan, since you still own the system in both cases. Leases and PPAs generally don’t qualify since the installer retains ownership.

This calculator provides a detailed estimate based on your electric bill, location, roof conditions, and financing choice. Actual savings can vary based on local installer pricing, exact shading, and utility rate changes, so we recommend getting quotes from certified installers to confirm final numbers.
