Free Solar Savings Calculator
Use your electric bill, ZIP code, and home size to estimate system size, cost, yearly savings, payback, and battery storage. Free, with no signup or phone number.
Transparent starting point
What this estimate uses—and what it cannot know yet
The calculator combines your ZIP code, electricity bill, home size, story count, and optional mapped roof outline with location and utility-planning assumptions. It is designed to help you ask better questions before a proposal, not to replace a roof inspection, electrical assessment, or written installer quote.
Shown transparently
System-size range, roof inputs, local electricity context, export assumptions, battery range, and current state-program context.
Still needs verification
Shade, roof condition, equipment, utility tariff, financing, permits, electrical work, and any personally eligible incentive.
