300+ days of sunshine, Xcel Energy net metering, and local rebates make Colorado a solar goldmine. Here's how to capitalize on it.
I recommend getting at least 3 quotes. EnergySage pre-vets installers and makes them compete for your business.

Here's the Colorado solar reality: You've got some of the best solar resources in the country (5.8 peak sun hours daily), but electricity rates are relatively low. The financial case depends heavily on which utility serves you and what local rebates you can stack. I've analyzed Xcel Energy's net metering changes and municipal utility programs.
If you're paying Xcel Energy rates in Denver or Boulder (and seeing those 4-6% annual increases), solar economics are solid but not California-level attractive. The real win is energy independence plus modest savings over 25 years.
| Incentive | Type | Amount | Status | Expires |
|---|---|---|---|---|
| Federal ITC (Solar Tax Credit) | Federal tax credit | 30% of system cost | Active | Dec 2032 (steps down) |
| Xcel Energy Solar Rebate | Utility rebate | $0.50/W (up to $2,500) | Limited budget | When budget exhausted |
| Net Metering | Export credit | Retail rate minus adjustments | Active | Grandfathered 20 years |
| Property Tax Exemption | Tax exemption | 100% for 10 years | Active | Through Dec 2025 |
| Sales Tax Exemption | Tax exemption | 100% on solar equipment | Active | Ongoing |
| Denver Rebate | City rebate | Up to $3,500 | Available | Budget-limited |
| Boulder County Rebate | County rebate | $1,000-$4,000 | Available | Varies by program |
Rebate availability varies significantly by utility territory and municipality. Check with your local government for current programs.
Xcel Energy serves Denver, Boulder, Fort Collins, and most of the Front Range. Their net metering program is more complex than most states, and the details can significantly impact your savings.
Under the old 1:1 net metering, a 8 kW system saving 100% of your electricity would eliminate your entire bill. Under current rules, you'll still have:
Bottom line: Solar still makes financial sense with Xcel, but payback periods are 2-3 years longer than neighboring states with better net metering.
With Xcel's net metering structure, system sizing is critical. Get personalized quotes to optimize your ROI.

Not all Colorado utilities are Xcel Energy. Many cities run their own electric utilities with more solar-friendly policies. If you're served by a municipal utility, you might have better economics.
Rural areas are often served by electric co-ops with varying solar policies. Some offer excellent net metering, others charge substantial interconnection fees. Check with your co-op before investing.
Key insight: If you're not served by Xcel Energy, you likely have better solar economics than the statewide averages shown above.
