How the estimate works

Site-specific production

Each address is geocoded and run through NREL's PVWatts model at your array's tilt to estimate annual output.

Your real utility rate

We identify the electric utility serving each location and apply its avoided-cost rate to the energy you'd offset.

Every incentive counted

Federal tax credit (higher in designated Energy Communities), depreciation, demand savings, and RECs feed a 25-year cash flow.
