Quick Answer
Denver is one of America's best solar markets—300 sunny days annually (NOAA data), more than San Diego or Miami. At 5,280 feet elevation, thinner atmosphere means 5-10% higher production than sea-level cities. Expect $2.60-3.20/watt with Xcel Energy net metering. Snow slides off quickly and actually boosts production via reflection. Typical payback: 8-11 years.
Solar in Denver
Denver's high altitude and abundant sunshine create excellent solar conditions. According to NOAA climate data, Denver averages 300 sunny days annually—more than San Diego or Miami. Despite cold winters, Denver's clear skies and reflective snow actually boost annual production, making it one of the best solar cities in the country.
From my experience:People are always surprised when I tell them Denver gets more sunny days than Miami or San Diego. That 300 days of sunshine isn't marketing fluff—it's real, and at 5,280 feet you're closer to the sun with less atmosphere in the way. Cold weather actually helps panels perform better. Snow? It slides off faster than you'd think. Denver is genuinely one of the best solar cities in America, and not enough people know it.
Denver Solar Advantage
Denver averages 300 sunny days and 5.5 peak sun hours daily. The Mile High City's altitude means thinner atmosphere and stronger solar radiation, boosting production 5-10% compared to sea-level cities. (Source: NREL Solar Resource Data)

Why Denver is Great for Solar
- Abundant sunshine: 300 sunny days, 5.5 peak sun hours
- Altitude bonus: Stronger solar radiation at 5,280 ft
- Snow reflection: Bifacial panels capture reflected light
- Xcel net metering: Good credit for excess generation
- Colorado incentives: Sales tax exemption, property tax exemption
Denver Solar Costs
Average System Costs
| System Size | Gross Cost | After Incentives* |
|---|---|---|
| 6 kW | $15,600-18,600 | $15,600-18,600 |
| 8 kW | $20,800-24,800 | $20,800-24,800 |
| 10 kW | $26,000-31,000 | $26,000-31,000 |
*Federal 25D credit ended Dec 31, 2025. PPA/Lease options still benefit from 30% through 2027.
Cost Per Watt
- Denver average: $2.60-3.10 per watt
- Budget installs: $2.40-2.60 per watt
- Premium installs: $3.10-3.80 per watt
Xcel Energy Programs
Most Denver residents are served by Xcel Energy, which offers decent net metering for residential solar customers.
Xcel Solar Programs
- Net metering: Credit at retail rate for excess generation
- Monthly rollover: Credits carry forward
- Annual true-up: Excess credits paid at avoided cost rate
- Solar*Rewards: Additional incentive program (check availability)
Xcel Net Metering
Xcel Energy credits excess solar generation at the full retail rate on a monthly basis. At year-end true-up, remaining credits are paid out at a lower "avoided cost" rate (~$0.03/kWh). (Source: EnergySage Marketplace Data, 2025)
Optimizing for Xcel
| Strategy | Benefit |
|---|---|
| Size for annual offset | Avoid low-value excess credits |
| Battery storage | Use more of your own power |
| Time-of-use awareness | Shift heavy loads to sunny hours |
Colorado Incentives
Available Incentives
- Sales tax exemption: No state or local sales tax on solar
- Property tax exemption: Solar value excluded from property tax
- Xcel Solar*Rewards: Performance-based incentive (if available)
- Low-income programs: Various assistance programs available
Federal Options
- Purchased systems: No federal credit (25D ended 2025)
- PPA/Lease: Still benefits from 30% credit through 2027
- Consideration: Compare purchase vs lease economics carefully
Mile High Considerations
Climate Factors
- Snow: Slides off quickly; panels self-clear in most cases
- Cold temps: Panels are MORE efficient in cold weather
- Hail: Colorado sees hail; choose durable panels
- UV intensity: Higher UV at altitude; quality panels handle it
Denver-Specific Factors
- Roof pitch: Steeper roofs shed snow faster
- South-facing ideal: Maximizes winter production when sun is lower
- HOAs: Colorado law protects solar rights
- Historic districts: Some areas have restrictions; check local rules
Production Estimates
- Annual production: 1,500-1,700 kWh per kW installed
- 8 kW system: ~12,000-13,600 kWh/year
- Best months: April-September
- Winter: Lower production, but cold = efficient panels
Winter Performance
Denver's cold, clear winter days can actually produce excellent solar output. Cold panels are more efficient, and snow reflection can boost production. Most snow slides off panels within 1-2 days. (Source: NOAA Climate Data)
The Bottom Line
Denver is excellent for solar. 300 sunny days, altitude-boosted production, and solid Xcel net metering make solar a smart investment for most Denver homeowners.
Key points:
- Denver gets more sun than most coastal cities
- High altitude = stronger solar radiation
- Snow is rarely an issue; panels self-clear
- Size system for annual usage to maximize value
- Consider hail-resistant panels for Colorado weather
