Your State
?
Your state determines the carbon intensity of your electricity grid — coal-heavy grids produce far more CO₂ per kWh than hydro or nuclear-heavy ones.

Monthly kWh Usage
?
Find this on your utility bill — it's more accurate than the dollar amount. US average is 886 kWh/month per household.
Transportation (Optional)
Gas Vehicles in Household
?
We estimate ~12,000 miles/year per vehicle at 25 MPG average. For precise calculation, use the Transportation tab.

System Size (kW DC)
?
Found on your installer's proposal, permit, or monitoring app (Enphase, SolarEdge). E.g. a typical home system is 5–12 kW.
Annual Production (kWh)
?
Check your Enphase Enlighten, SolarEdge, or utility net-metering bill. More accurate than calculating from system size.
Your State
?
Determines your grid's carbon intensity (EPA eGRID 2024). CO₂ saved in West Virginia is ~9× more than in Washington State per kWh.

System Age (years installed)
?
Optional. For a new/planned system enter 0. We'll show what your system will save over its 25-year lifetime. Panel degradation of 0.5%/year is applied.
