What makes Denver different
1. Xcel Energy sets the interconnection rules
Denver sits in Xcel Energy territory. Interconnection, the export credit rate and any capacity caps all come from that utility and are subject to change — confirm the current rules before signing a contract.
2. Export credit treatment matters more than panel brand
How exported power is credited has a bigger effect on payback than which panels you buy. Size to your own annual usage first, then pick equipment.
3. Net metering, but mid-transition
Exports are still credited close to retail in Denver, but the policy is being phased down in many markets. Grandfathering rules and application dates matter — check the current schedule before signing.
What affects your price in Denver
- System size — the single biggest driver.
- Roof pitch and height — steep or two-storey roofs add labour.
- Roof age — replace worn shingles first; re-roofing around panels costs more later.
- Panel and inverter tier — premium modules and microinverters add 15–25%.
- Main panel upgrade — older homes may need a 200A service upgrade, $1,500–$3,000.
- Battery — optional, roughly $10,000–$15,000 installed.
- Season — late autumn and winter installs are often cheaper.

How long is the payback period in Denver?
Roughly 7.6 years for a properly sized system, based on local rates, 1750 kWh of production per installed kW, and current incentives.

A 6 kW array needs roughly 390–510 square feet of unshaded roof, depending on panel wattage and layout.

The sun resource is strong at about 1750 kWh per installed kW per year, and local rates run near 15¢/kWh. The real variables are roof condition, shading and Xcel Energy's export credit rules.
