Solar power in Washington (state)

As of the first quarter of 2023, Washington State has 604 MW of solar power electricity generation.^[1] This is an increase from about 300 MW in 2021 and 27 MW in 2013.

Washington pays a feed-in tariff of up to $5,000/year of 15 cents/kWh, which is increased by a factor of 2.4 if the panels are made in the state and by an additional 1.2 if the inverters are made in state.^[2]^[3]

Amount of sunlight

The average insolation in Washington's two largest cities are as follows.

In the charts, a peak sun hour is one kilowatt-hour per square meter of solar irradiance.^[4]
