Annual solar production planning estimates

Each row uses the same state planning yield for every system size. Multiply kWh/kW-year by installed DC kW to get the annual production shown below.

How to use this table

Use it to compare broad state-level solar resource, sanity-check an installer production claim or estimate output for a standard system size. It is not a substitute for a roof-specific forecast.

State solar yield is a planning estimate derived from NREL residential PV resource-class ranges, not a site-specific PVWatts result.

Why the same state can contain very different roofs

Production varies with latitude, local weather, elevation, shade, roof direction, roof tilt, inverter sizing and system losses. A state number is useful for screening and comparison, while a ZIP-level or address-level model is better for a purchase decision.
