Three Numbers That Change Everything
Solar economics reduce to three numbers. Your current bill. The savings solar produces against it. And what you actually keep paying. Every other figure on this site flows from these.
The monthly utility bill you pay today, on a $0.14/kWh national average.
The portion replaced by your rooftop solar production over a 25-year system life.
What's left: small grid connection fees and minor draw on cloudy days.
30% Back. No Cap. No Income Limit.
The federal Investment Tax Credit returns 30 cents on every dollar you spend on solar — panels, inverters, batteries, labor, and roof prep. There is no household income test, no cap on system size, and no expiration before 2033. Most homeowners claim it on Form 5695.

Every state has different rules. Know yours before you buy.
Three Calculators. One Decision.
Each tool answers one question. Combine them to plan a complete install.
Explore by Incentive Type
Stack everything you qualify for. Federal credit, state credit, net metering, SRECs, exemptions, utility rebates.
Net metering credits homeowners for excess solar energy sent back to the grid, often at retail or near-retail rates.
Solar Renewable Energy Certificates (SRECs) are tradable credits earned for every megawatt-hour of solar electricity produced.
A solar property tax exemption excludes the added home value from solar from your annual property tax assessment.
Solar sales tax exemptions remove state and local sales tax from solar equipment purchases at the point of sale.
Several states offer income tax credits that stack on top of the federal 30% Investment Tax Credit.
Many electric utilities offer upfront rebates that lower the cost of solar installation, typically distributed first-come, first-served.
