Solar CO₂ Savings Calculator

Accuracy note: The arithmetic on this page is deterministic from your inputs. Solar production, code, utility, incentive, and savings outputs are estimates unless you supply exact equipment specs, tariffs, shade data, and local requirements.

How this is calculated

Avoided CO₂ = avoided kWh × regional marginal emission factor. Enter an EPA eGRID/AVERT factor for your region when possible; this default is only a placeholder.
