Add Battery Backup to the Solar You Already Have
Your panels shut off when the grid goes down. A battery keeps your home running and stores your solar for the evening. We check what you have, tell you straight what will work, and handle the permits and utility paperwork.
Why add a battery to solar you already have
- Grid-tied solar is required to shut off during an outage, even on a sunny day.
- A battery gives automatic backup for the circuits you choose (fridge, furnace blower, well pump, internet, medical equipment).
- Stored solar can help with evening time-of-use hours.
- Rural and foothill homes often see longer outages, and Xcel can call Public Safety Power Shutoffs in higher wildfire-risk areas.
Will a battery work with my system?
It depends on your inverter, your main electrical panel and who owns the system. We confirm on a free site visit.
SolarCity or Tesla panels
We add battery backup to SolarCity/Tesla panel-only systems after checking the inverter and panel setup.
Enphase microinverters
Enphase batteries are designed to pair with Enphase microinverter systems, so they're usually the first option we look at.
SolarEdge and other string inverters
We review your inverter and recommend a compatible battery from the brands we're certified on.
Leased or PPA systems
We'll review your lease terms before designing anything.
Systems from installers who've gone out of business
We service and add batteries to systems we didn't install.
Tell us your inverter brand (it's on the equipment near your meter or in your monitoring app) and we'll tell you over the phone if a battery is likely to fit.

How the install works
Load Assessment
We evaluate what you want backed up — essentials or whole home — and size the battery to match.
Design & Permits
We engineer the system, pull electrical permits, and handle utility interconnection paperwork.
Installation
Our licensed electricians mount the battery, wire the backup circuits, and integrate it with your solar.
Commissioning
We test backup switchover, pass inspections, and set up your monitoring app so you're in control.
Most battery installs take one day on site once permits and utility approval are in.
Colorado battery incentives in 2026
The federal residential clean energy credit ended for systems installed after December 31, 2025.
Xcel Energy's Renewable Battery Connect's general tier pays $250 per kW AC of maximum continuous discharge power, up to $5,000 per application, for a new battery paired with new or existing solar. Only Tesla Powerwall and current Enphase IQ batteries qualify, and Xcel can use part of the battery during a limited number of peak events. As of November 2026; confirm current terms with Xcel. Official Xcel Renewable Battery Connect page · Our Renewable Battery Connect guide · All Xcel battery rebates
Colorado offers a state income tax credit equal to 10% of a residential energy storage system's purchase price (equipment, not installation labor).
Residential energy storage is exempt from Colorado's 2.9% state sales and use tax.
Program terms change. Confirm current program terms with Xcel Energy and the Colorado Department of Revenue, and talk to your tax professional about credits. We list what your address may qualify for in your quote.
Backed by a 10-year workmanship warranty
Every battery we install carries our 10-year workmanship warranty, on top of the manufacturer's equipment warranty.
Recent battery add-ons
A Kiowa homeowner with existing solar wanted backup for rural outages. We assessed the system and designed battery backup around the loads that matter most.
An Aurora homeowner with a SolarCity panel-only system asked to add battery backup. We checked compatibility and quoted a battery add-on.
