More Information on Colorado Green Energy

Surprising to many who have never been there – because Colorado is often known for it’s snowy mountains – is that Colorado has a great level of peak sun hours for solar power production. There are on average 136 perfectly clear days a year, and plenty more days where solar power production is still possible. One of the advantages of being high in the mountains is that you often get clear skies. Colorado also has very favorable net metering laws, with great incentives for citizens to accept the up front cost for putting a solar system on your home.

With a lot of sunny days a year, Colorado is a very green state and offers great incentives for solar power in homes or companies.

In the Southern part of the state, like near Alamosa Colorado, the peak sun hours is even higher, and is competitive with some of the best areas in the country for solar insolation.
