• Boulder, CO GOES SOLAR WITH SUNPOWER®

    Solar power is rocking this Rocky Mountain city

The state of solar in Boulder

Boulder takes clean energy seriously, and many residents have already made the switch to solar power. The city declared a Climate Emergency on July 23, 2019, at which time it created a goal to utilize 100% renewable energy by 2030. Because Boulder experiences 245 sunny days each year,* the city is in a prime location to use solar energy to its full potential.


How much solar energy does Boulder produce?

Boulder has a total installed solar capacity of 44 MW as of April 2020, equating to .411 kW per capita. Roughly 19 KW (43.18%) comes from non-residential sources, 19 MW (43.18%) from residential, and 6 MW (13.64%) from government sources.

The City of Boulder has 19 municipal solar electric systems with a total installed capacity of over 2 MW. It also utilizes two solar thermal systems to heat public swimming pools.

What are the advantages of going solar in Boulder?

Switching to solar energy can help reduce Boulder’s carbon emissions. If Boulder met its solar capacity of 482,000 MWh per year, carbon emissions would decrease by 294,000 metric tons, the equivalent of taking 62,100 cars off the road for a year. *

Living in Boulder also puts you in a unique position to take advantage of the city’s specialized solar rebates and grants to reduce your overarching costs.* Even without these programs, solar can offer significant electricity cost savings. A 5-kW system could pay for itself within a decade and offer upwards of $15,000 in savings over 20 years.*

Boulder wants to make it as easy as possible for homeowners to switch to solar energy, too. The city enacted a solar access ordinance that guarantees access to sunlight by limiting the amount of shading that new construction can create.
