Rooftop solar output, 1 kW system.
This measure has no better end. The order describes the states, it does not rank them — see the other direction.
Estimated annual electricity from a 1 kW fixed roof-mounted photovoltaic system at the county’s population-weighted center. This is solar resource potential, not a roof quote: it does not account for roof orientation, shading, panel choice, system losses, local incentives, or your electricity use.
Alaska has the lowest published rooftop solar output in this comparison, at 956 kWh/yr. The next states shown are Washington (1,130 kWh/yr) and Oregon (1,219 kWh/yr).
The table orders 51 states by rooftop solar output, 1 kw system. It describes one published measure, not an overall judgment about where to live.
Use the result as a starting point, then compare the underlying source, dates, and local county figures before making a decision. Estimated annual electricity from a 1 kW fixed roof-mounted photovoltaic system at the county’s population-weighted center. This is solar resource potential, not a roof quote: it does not account for roof orientation, shading, panel choice, system losses, local incentives, or your electricity use.
Free to use. The chart names its source and links back, so it stays honest wherever it ends up.
