Solar Savings Calculator for homeowners comparing real tradeoffs.

Estimate your recommended system size, monthly savings, tax credit value, payback period, and long-term utility comparison in one place. The assumptions are visible by design.

Quick estimate first, installer conversations later. Results are designed to be transparent and educational.

Interactive calculator

Estimate solar savings with a few inputs.

Start with your monthly bill, then refine the model with usage, financing, roof, and utility assumptions.

Educational estimate only. Use it to get grounded before comparing installer quotes.

System size

Leave blank to let the calculator estimate a recommended size.

Payment method
Results update automatically as you type. This MVP uses realistic placeholder assumptions today and is structured for future utility rate, geolocation, and proposal comparison integrations.

Your estimate

Enter your monthly electric bill to unlock the calculator.

We only require one input to get started. You can add utility rate, usage, financing, and roof details afterward to refine the result.

Start with your monthly bill

No phone number required. Illustrative estimate only.

Start estimate

Fast inputs above the fold

A homeowner can get to a first estimate with a single required input: monthly electric bill.

Clear output hierarchy

Savings, tax credit, payback, and long-term comparison are presented in plain language without burying the result.

Future growth built in

The architecture is ready for utility lookups, report generation, analytics events, and lead capture workflows.

Calculator FAQ

Questions people ask when they want a grounded solar estimate.

These answers are written for homeowners trying to understand the estimate, not for a sales script.

How is the recommended system size estimated?

The model starts with annual usage, then works backward using a production-per-kW assumption adjusted for sun exposure and roof shading. If you enter a system size manually, that input overrides the estimate.

Does the calculator include the federal solar tax credit?

Yes. The calculator applies the federal tax credit percentage you enter, with a default of 30%, to estimate net cost after incentives.

How does financing affect the estimate?

When loan mode is selected, the model estimates a monthly payment using your down payment, term, and interest rate, then compares that payment plus residual utility spend against your current bill.

Why is there still a utility bill after going solar?

Many homes still have a minimum connection charge, seasonal shortfalls, or less than full offset. The model keeps a residual utility amount to reflect that reality.

Future next step

Save your estimate, compare proposals, or request a real quote when you are ready.

This MVP is intentionally built to support future lead capture without turning the current experience into a gated funnel.

Important note

This tool is educational, not a binding solar quote.

Real pricing and solar production vary with roof geometry, equipment, utility billing rules, installer design choices, financing terms, and local regulations. Review our full disclaimer before using any estimate to make a purchase decision.
