Savings planner
Clean energy decisions should connect environmental goals with understandable utility savings, resilience value, equipment longevity, and responsible expectations about incentives.
Savings demo
Solar value changes by utility rate, net metering rules, roof production, installation cost, and financing method. Battery value depends on outage frequency, time-of-use spreads, selected loads, and usable kWh. Eligible residential customers may qualify for federal tax incentives subject to IRS guidelines, while state and utility programs can differ substantially.
This calculator layout is intentionally an input guide rather than a guaranteed payback claim. A trustworthy estimate should show assumptions, sensitivity, and the difference between energy savings and resilience value.
Case patterns
A well-sited PV array can reduce purchased electricity and expose the home to less utility price volatility, but annual results depend on weather, shading, export rules, and consumption changes.
A battery can keep selected loads running and shift some solar production into evening hours. Sunrun explains runtime through load choices instead of using broad, absolute claims.
Homes planning EV adoption can align solar generation, charging schedule, and electrical service upgrades to avoid expensive redesign after installation.
Sunrun can help compare solar panels, batteries, EV charging, and financing based on your home, not an average household that may not look like yours.
