Did you know that the claim “Colorado gets more than 300 days of sun a year” is actually a myth that dates back to the 1870s? It was started by railroad companies advertising Colorado’s beautiful climate to people on the east coast in hopes that they’d visit.
That said, we still get a ton of sun! Colorado actually has around 280 sunny days a year, putting us ahead of places like San Diego and Miami.
With all that sun, plus more UV radiation at elevation (UV radiation increases by about 4% for every 1,000 feet of elevation), Colorado is one of the most productive states for solar in the country.
