A real cost breakdown for a typical 6kW system in Boulder, using local rate and sun-hour data rather than a state-wide average.
Boulder has a fairly typical electricity rate nationally at approximately $0.14/kWh, and excellent solar resource — among the sunniest metro areas at 5.7 peak sun hours a day — notably different from a simple Colorado state-wide average in some cases, since metro-level microclimates and local utility rates can diverge from state figures. Combined with a metro-level installed-cost estimate of $2.80/watt, a standard 6kW residential system runs approximately $14,680 before any incentives.
| Line item | Estimated cost | Share of total |
|---|---|---|
| Equipment (panels, inverter, racking) | $9,240 | 63% |
| Labor / installation | $5,040 | 34% |
| Permitting & inspection | $400 | 3% |
| Total (before incentives) | $14,680 | 100% |
A 6kW system in Boulder costs 15% less than the 50-state average of $17,372, and the electricity rate it offsets is 13% lower than the $0.16/kWh average across those states. At $1,398 in estimated annual value from 9,986 kWh of yearly production, this system pays back in roughly 10 years — a payback period in line with the national average.
A typical 6kW residential solar system in Boulder costs approximately $14,680 installed in 2026, based on a metro-level estimate of $2.45/watt.
At Boulder's average rate of $0.14/kWh, a 6kW system pays back in roughly 10 years — a payback period in line with the national average.
