Utility rules and programs for Centennial
Xcel Energy and CORE Electric serve Arapahoe County, so which rules apply depends on your address.
| Utility | Type | Solar export rule |
|---|---|---|
| Public Service Co of Colorado | investor-owned | Xcel Energy net-meters rooftop solar under state law: what you send to the grid offsets what you take, extra credits roll forward as a bank, and systems are sized so expected output is no more than 200% of your last 12 months of use. Time-of-use or flat rate changes how credits are valued; do not start building before approval (page read Oct. 2026). |
| CORE Electric Cooperative | member-owned cooperative | CORE net-meters homes with systems of 10 kW AC or less and no more than 200% of 12-month use. Extra energy carries forward, and a yearly true-up (within 60 days after the April billing cycle) pays any remainder at its avoided cost. Larger systems are not net-metered and are paid its avoided cost, 4.616 cents per kWh from May 2026. |
Program details are from each utility’s own pages (read October 2026). See the Colorado incentives table for statewide credits and a status for every program.

Solar Panel Installation in Centennial FAQs
Is solar worth it in Centennial?
The sun is strong (about 1,420 kWh a year per kW, our estimate), but export credits are low, so solar pays most when sized to what you use at home or paired with a battery. See the Colorado incentives for the state credit.
Is there a federal solar tax credit in 2026?
No. The federal 25D credit ended for expenditures after December 31, 2025. Colorado has no state solar income tax credit that we could confirm; its state benefits are the residential property-tax exemption and sales and use tax exemptions for solar components and home batteries.
Do I need a permit for solar panels in Centennial?
Usually yes, and the utility may need to approve solar and batteries. City of Centennial Building Division handles permits in Centennial; see the permit information above.
