The Real Question Colorado Homeowners Are Asking

Is It Financially Worth It?

For many Colorado homeowners, yes — especially with the right use case and incentive timing.

Adding a battery helps you:

1. Avoid peak utility rates by using stored energy when grid costs spike.
2. Store unused solar power rather than exporting it back at low net metering rates.
3. Maximize self-consumption, meaning more of your solar power stays in your home.

Example: A homeowner in Colorado Springs with TOU billing can save up to 40% more per year on energy bills with a solar battery compared to panels alone.

Smart pairing: Batteries make the most sense when:

1. You’re already generating more solar than you use midday.
2. You experience grid outages or bad weather.
3. Your utility has TOU or demand charges.

Top Benefits of Solar Battery Storage

Solar batteries go beyond savings. Here’s why your neighbors are adding them:

1. Backup During Blackouts

1. Stay powered during storms, wildfires, and outages
2. Protect essentials: medical devices, refrigeration, internet

2. Time-of-Use Arbitrage

1. Store cheap daytime power
2. Use it when rates are highest — typically 4-9PM in Colorado

3. Energy Independence

1. Reduce reliance on the utility grid
2. Support sustainable living and climate goals

4. Increase Home Value

1. Homes with solar + storage systems are more attractive to buyers
2. Adds resilience and modern appeal

What It Costs (and How to Save)

Adding a solar battery in Colorado typically costs $9,000–$16,000, depending on:

1. Battery brand and size (e.g. Tesla Powerwall vs Enphase)
2. Whether you need an inverter upgrade
3. Local permit and installation costs

Incentives That Can Cut Your Costs:

1. 30% Federal Solar Investment Tax Credit (ITC)
2. Local utility rebates (check Black Hills Energy or Xcel Energy programs)
3. Property tax exemptions for home solar upgrades in Colorado

Many of our customers pay less than $8,000 out-of-pocket after credits.

Will It Work With My Current Solar System?

In most cases, yes — your system can be retrofitted with the right hardware.
