Solar power in Washington (state)

Solar power in Washington expanded to over 27 MW in 2013, largely due to a 30% federal tax credit, and declining installation costs. Washington also 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.[1][2] By 2021, Washington has almost 300 MW of solar power.

Statistics

The average insolation is approximately 19% higher in Spokane than in Seattle.
