Battery Backup for Silverthorne Homes
In deep winter cold, an outage can put pipes at risk. Plan backup for heat circulation and freeze protection.
Battery Storage for Silverthorne homes
Silverthorne and Frisco sit high in Summit County, where winter nights fall well below zero. When the power goes out in that cold, the risk isn't just darkness, it's pipes and heating systems freezing.
We size battery backup to keep heat circulating and freeze protection running, along with the fridge and internet. The battery switches over on its own, and every install carries our 10-year workmanship warranty.

Why Silverthorne loses power
In August 2024, Silverthorne officials raised repeated summer outages with Xcel, which tied some of them to Enhanced Powerline Safety Settings, as the Summit Daily reported. Silverthorne had a high number of outage reports.
Winter brings a different risk. In January 2025, about 6,654 Xcel customers around Silverthorne and Dillon lost power with temperatures below minus 15, per Denver7.

Silverthorne battery backup FAQs
Can you add a battery to my existing solar in Silverthorne?
Usually. We check the inverter, panel and ownership, and look at how much winter sun your array actually gets before recommending storage. If your system is leased, we'll review your lease terms.
Will a battery keep my Silverthorne heat running in a deep-cold outage?
It can keep circulation going, such as a furnace blower or boiler pumps, for a period that depends on usage. Electric resistance heat draws far more, so we usually prioritize circulation and freeze protection and show runtime estimates.
Why does Silverthorne seem to lose power more in summer?
Xcel's enhanced safety settings make lines trip more readily during fire-risk conditions, and town officials raised repeated summer outages with Xcel in 2024. A battery covers your chosen circuits during those trips.
Which batteries suit Silverthorne homes, and how big should one be?
We're certified on Enphase, Tesla Powerwall, Franklin (FranklinWH) and EG4. We size around heat circulation, freeze protection, the fridge and internet, accounting for limited winter recharge. All installs carry a 10-year workmanship warranty.
