Utility rules and programs for Westminster
Xcel Energy serves homes in Westminster.
| 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). |
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 Westminster FAQs
Is solar worth it in Westminster?
The sun is strong (about 1,380 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 Westminster?
Usually yes, and the utility may need to approve solar and batteries. City of Westminster Building Division handles permits in Westminster; see the permit information above.
