How Much Does Solar Panel Installation Cost in Denver?

Denver is one of the top solar markets in the US, ranking in the top 10 cities nationally for solar installations per capita. Denver averages 300 sunny days per year - more than Miami or Los Angeles - and sits at 5,280 feet elevation where the thinner atmosphere reduces UV filtering, resulting in 10-15 percent higher solar irradiance than comparable southern US cities. Colorado solar incentives, Xcel Energy net metering, and Colorados status as a renewable energy leader have driven solar adoption across metro Denver neighborhoods from Capitol Hill to Cherry Creek, Aurora, Littleton, Arvada, Westminster, and Thornton.
