How Colorado compares
Colorado gets more sunlight than 75% of the cities we measure, and its electricity costs more than 46% of states and provinces. Both matter, but not equally: the electricity rate usually matters more, because solar saves money by replacing power you would otherwise buy. A sunny state with cheap power often pays back slower than a cloudy state with expensive power. Why that happens →

What a system costs in Colorado
| System | Size | kWh/yr | Net cost | Saves/yr | Payback |
|---|---|---|---|---|---|
| 8 panels | 3.2 kW | 4,673 | $6,384 | $692 | 9.2 yrs |
| 12 panels | 4.8 kW | 7,009 | $9,576 | $1,037 | 9.2 yrs |
| 16 panels | 6.4 kW | 9,346 | $12,768 | $1,383 | 9.2 yrs |
| 20 panels | 8 kW | 11,682 | $15,960 | $1,631 | 9.8 yrs |
| 26 panels | 10.4 kW | 15,187 | $20,748 | $1,761 | 11.8 yrs |
Payback stops improving as systems grow, then gets worse. You can only save on electricity you were going to buy, so once a system covers your usage the extra panels mostly export at a lower rate.
Colorado solar incentives
Every US household can claim the 30% federal residential clean energy credit, which is what the "after credit" figures above assume. On a $21,660 system that is $6,498 back. How the credit works →
State, utility and municipal incentives stack on top and change often — Colorado may offer rebates, property or sales tax exemptions, or performance payments. We deliberately don't list specific state programmes here because they change several times a year and stale numbers are worse than none. The DSIRE database is the standard reference and is kept current.
