Solar Savings Calculator
See what solar could save you
Enter your address and electricity bill to estimate your roof's solar potential, possible annual electricity savings, and simple payback period.
Start your savings estimate
Connect your roofto your real bill.
Analyze your roof, then add an average monthly bill to see existing financial results where supported.
The useful distinction
How does the solar savings calculator work?
SunMyRoof combines available roof and solar information with your electricity usage or bill and supported regional assumptions. The result connects the physical question—how much electricity your roof could produce—with the financial question—how much grid electricity that production may offset.
These are preliminary estimates rather than guaranteed savings. Local pricing and installation assumptions are used only where the application has supported data.
The bigger question
Wondering whether solar is worth considering?
Put your roof potential and available savings evidence together in a property-specific assessment.
No universal number
How much money can solar panels save?
Two homes with similar roofs can have different financial outcomes. Savings depend on the relationship between the electricity a household uses and the electricity its system may produce.
Solar production
Roof geometry, sunlight, shade, orientation, and system size affect output.
Local rates
Electricity pricing determines the potential value of each kilowatt-hour.
Installation cost
A preliminary cost range is available only where supported local assumptions exist.
A simple planning measure
What determines your solar payback period?
Simple payback is an estimate of installation cost divided by estimated annual savings. It provides a quick way to compare the upfront cost with the potential yearly value of solar.
It is not a complete investment-return calculation. Electricity-price changes, system performance, incentives where applicable, financing, maintenance, equipment replacement, and future conditions can change the outcome.
Why your electricity bill matters
The bill helps estimate the relationship between potential solar production and household electricity consumption. Two identical roofs can have different savings when the households use different amounts of electricity.
Solar savings vs. solar production
Production is how much electricity a system may generate. Savings are the potential financial value of electricity solar may offset. Want to focus on roof capacity and production potential? Use our Solar Panel Calculator.
How accurate are solar savings estimates?
Estimates depend on available roof and building data, solar-resource estimates, your bill, regional electricity assumptions, supported installation-cost assumptions, and actual future system performance.
They are for preliminary planning—not guaranteed savings, contractor quotes, engineering designs, or final installation proposals. Actual utility billing and installed costs may differ; taxes, incentives, financing, maintenance, and future rates may affect economics.
Questions, answered plainly
Solar savings FAQs
Is the SunMyRoof solar savings calculator free?
Yes. SunMyRoof is free to use and does not require an account to analyze your roof or explore a preliminary savings estimate.
How much can solar panels save on my electricity bill?
Savings vary with your electricity consumption, solar production, rates, system size, installation costs, and other property-specific factors. Use your address and average bill for a more useful preliminary estimate.
Why do you need my electricity bill?
Your bill helps estimate current electricity spending and usage, then compare that household demand with how much solar production could potentially offset. The bill input stays in your browser.
How long does it take solar panels to pay for themselves?
Payback varies substantially based on installation cost, annual electricity savings, system performance, local rates, and other assumptions. A property-specific estimate is more useful than a universal payback number.
Does a bigger solar system always mean more savings?
No. A larger system may produce more electricity, but household consumption, export value, electricity rates, system economics, roof conditions, and the amount of energy used at home all matter.
Is this a solar installation quote?
No. SunMyRoof provides preliminary planning estimates. It does not provide a contractor quote, final engineering design, or installation proposal.
