Based on 93% data coverage over buildings in this geographic area. All estimates are based on buildings viable for solar panels. Included panels receive at least 75% of the maximum annual sun in the county. For Colorado, the average value of the threshold is 1,250 kWh/kW. Read about Project Sunroof’s methodology for defining solar viability below.

Estimate methodology

This tool estimates the technical solar potential of all buildings in a region. Technical potential includes electricity generated by the rooftop area suitable for solar panels assuming economics and grid integration are not a constraint. There are many definitions of technical potential, and other definitions may affect results by 25% or more. Based on Project Sunroof’s definition of technical potential, installations meet the following criteria:

Sunlight
Every included panel receives at least 75% of the maximum annual sun in the county. For Colorado, the average value of the threshold is 1,250 kWh/kW.
Installation size
Every included roof has a total potential installation size of at least 2kW.
Space & obstacles
Only areas of the roof with enough space to install 4 adjacent solar panels are included. Obstacles like chimneys are taken into account.
