Why Colorado is Perfect for Solar Energy

Abundant Sunshine

Colorado enjoys approximately 300 sunny days per year with exceptional solar radiation levels, ranking among the sunniest states in the nation. The state’s high elevation increases solar radiation by approximately 2% per 1,000 feet, making Colorado ideal for maximum solar energy production.

100% Property Tax Exemption

Colorado provides a complete 100% property tax exemption for residential renewable energy systems. Your solar installation adds no additional property tax burden, allowing you to benefit from increased home value without proportional tax increases for the system’s lifetime.

Strong Net Metering

Colorado mandates net metering for customer-generators, allowing systems up to 200% of annual electricity consumption. Solar owners receive retail rate credits for excess energy sent to the grid, maximizing savings and accelerating payback periods throughout the state.

Federal Tax Credit Expiring

The 30% federal Investment Tax Credit expires December 31, 2025, representing the final opportunity for maximum federal savings. Combined with Colorado’s 100% property tax exemption, robust net metering, and abundant sunshine, 2025 offers optimal solar investment conditions.
