Salt Lake City Solar Overview
Salt Lake City combines excellent sunshine with high-altitude solar advantages. At 4,200+ feet elevation, the thinner atmosphere means more intense solar radiation. Rocky Mountain Power's net metering and Utah's incentives create a favorable market for residential solar along the Wasatch Front.

Costs & Savings in Salt Lake City
Typical System Costs
| System Size | Gross Cost | Annual Savings |
|---|---|---|
| 5 kW | $13,500-15,000 | $700-850 |
| 7 kW | $19,000-21,000 | $1,000-1,200 |

Savings Estimates
- Annual production: ~1,300 kWh per kW (altitude boost)
- Annual savings: $145-175 per kW
- Payback period: 11-15 years
- 25-year savings: $16,000-28,000
High Altitude Solar Advantage
Why Altitude Matters
Salt Lake City's elevation provides a meaningful solar boost:
- Thinner atmosphere: Less filtering of solar radiation
- More intense light: 5-10% more irradiance than sea level
- Clear skies: Low humidity = consistent production
- Cold efficiency: Panels work better in cooler temps
Winter Considerations
- Snow: Moderate; panels typically self-clear due to tilt
- Inversions: Smog inversions can temporarily reduce production
- Cold temps: Panels more efficient when cold and sunny
- Short days: Winter daylight shorter; offset by summer
The Bottom Line
Salt Lake City is a solid solar market with altitude advantages.Excellent sunshine and high elevation boost production. Moderate electricity rates mean payback periods of 11-15 years—reasonable for the Mountain West.
Best candidates: Homeowners with south-facing roofs, electric bills over $100/month, and plans to stay 10+ years. The altitude production boost helps offset Utah's moderate electricity rates.
Watch for policy changes: Utah's net metering policies have evolved. Check current Rocky Mountain Power terms before making decisions.
