What Denver homeowners should check

Denver benefits from clear high-altitude sun, but snow, hail, freeze-thaw cycles, and strong Front Range winds affect equipment choices. Roof condition, impact-rated modules, snow shedding, and safe placement above walkways should be discussed.

Xcel Energy serves much of the metro area, while some addresses use municipal or cooperative utilities. Confirm the provider and current net-metering rules before finalizing system size.

At the state level, Colorado currently uses full retail net metering. A typical interconnection takes 3–7 weeks, but utility review and local permitting can extend that range. Check current rules before relying on a proposal's export-credit or installation-date assumptions.

What should I verify before signing a solar contract in Denver?

Confirm that the quote names your actual utility, uses a recent electricity rate, includes measured shade and roof-condition findings, and explains who handles permits and interconnection. Ask the installer to separate guaranteed equipment and workmanship terms from estimated production, incentives, and savings.

Illustrative 5.4 peak sun hours, 14.08% production losses, 14.0 cents/kWh and $2.9/W. The retail-value ceiling assumes every kWh earns retail value; lower export credits reduce it. The cost/value ratio is not a full payback model and excludes repairs, financing and rate changes. No new Section 25D homeowner credit in 2026.
