Solar electricity value calculator

Explore the annual value of solar electricity using production, self-consumption and export-credit assumptions.

Enter an annual generation estimate from a system design or production model. This tool values that energy; it does not predict production from your roof.

Worked example

8,000 kWh with 60% used at home at $0.20/kWh and 40% exported at $0.05/kWh gives $1,120 in annual energy value.

Calculation and limits

Generation × self-consumed share × avoided rate + exported generation × export credit. Excludes installation cost, financing, maintenance, incentives, degradation and time-varying settlement; this is not a payback or savings guarantee.

Change one assumption at a time to see how it affects the result. No calculation sends your inputs to a remote service or requires an account.
