Solar Battery Backup for Windsor Homes
Backup for the circuits you choose, with your Windsor utility account and permit path confirmed before we design.
Battery Storage for Windsor homes
Windsor reaches across the Weld and Larimer county line, and homes here range from established houses to newer construction. Before we design a battery, we confirm which utility serves your address and which county reviews the permit, so nothing about the plan rests on a guess.
Then we size the battery around what you want running when the grid drops, such as the fridge, furnace blower, internet and a few lights, and check how it works with solar you have now or plan to add. Every Windsor install carries our 10-year workmanship warranty.

Your utility and programs

Windsor battery backup FAQs
Is my Windsor home served by Xcel Energy?
Most Windsor homes are, but we don't assume. We confirm the electric provider on your account before we design, because battery programs and interconnection steps depend on the utility.
Does it matter that Windsor is in two counties?
It can affect permitting. Windsor spans Weld and Larimer counties, so we confirm which authority reviews the permit for your address and handle the paperwork.
Can you add a battery to my existing solar in Windsor?
In most cases, yes. We check your inverter, main panel and system ownership, then recommend a battery that fits. If your system is leased, we'll review your lease terms.
Which battery brands do you install in Windsor?
We're certified on Enphase, Tesla Powerwall, Franklin (FranklinWH) and EG4, and we recommend the one that suits your backup list and any solar on the roof. Every install carries a 10-year workmanship warranty.
