The utility behind Silverthorne’s bills
According to the Colorado Energy Office’s utility-territory map, Silverthorne is served by Xcel Energy (Public Service Company of Colorado), an investor-owned utility that banks exported solar as kWh credits that offset later use one-for-one.
As always, the utility printed on your bill beats any map; we verify it by address before quoting.
Designing for Silverthorne’s conditions
At roughly 8,790 feet, Silverthorne is high-country solar: intense sun and cold temperatures that suit panels, paired with heavy snow loads, short winter days behind ridgelines, and outage exposure that often makes a battery as valuable as the array.
Getting a solar permit in Silverthorne
Permits for solar in Silverthorne come from whichever office holds building and electrical authority for your address — the town, Summit County, or, in many smaller Colorado jurisdictions, the State Electrical Board for electrical permits. We identify the right office and pull the permits as part of the job.
