What affects solar savings in Colorado?
Every homeowner's solar savings are different. In Colorado, the key variables are:
- Electricity rate (14.2¢/kWh): Colorado's electricity rate is near the national average. Combined with sun hours and system size, this gives a typical homeowner a solid case for solar investment.
- Peak sun hours (5.5 hrs/day): Colorado's solar resource is solid — comparable to Germany, which has one of the highest solar adoption rates in the world. Year-round production will be consistent.
- System size (8kW typical): The right size depends on your electricity bill. A $150/month bill typically requires a 6–8kW system to offset 80–100%. Use our System Size Calculator to find your exact target.
- Roof type and orientation: South-facing roofs at 30° pitch are ideal. West-facing roofs produce 15–20% less but may generate more electricity during peak-price afternoon hours, improving time-of-use savings.
