Solar Incentives Available in Denver, Colorado
Beyond the federal ITC, Denver homeowners may qualify for Colorado state incentives, local utility rebates, and property tax exemptions on the added home value from solar.
"The 30% federal Investment Tax Credit remains the single most powerful solar incentive in 2026 — but it only applies to systems you own outright (purchase or solar loan). If you're comparing a lease vs. loan, run the numbers on the ITC value first. For most homeowners, ownership beats leasing by $8,000–$15,000 over 25 years. Always get at least 3 quotes and verify NABCEP certification before signing any contract."
