Frequently Asked Questions

The program is available for residential customers in CEA’s service territory who already have an existing solar system and do not own a battery.

A solar and battery storage system lets you generate and store electricity to use whenever you like. By producing your own energy, you can lower your electric bills. Electricity gets stored in your battery, which you can use to power your home when time-of-use rates are most expensive.

  1. Energy savings: Homeowners with solar and battery systems can save on energy costs by using stored power when rates are most expensive.
  2. Backup power: With a solar and battery system, homeowners can secure reliable power during an outage
  3. Lower CO2 emissions: Producing and storing renewable energy lowers your household emissions by over 2,600 lbs of CO2 a year

A battery system stores electricity from the power grid or from solar panels. Most batteries are made of lithium-ion technology, similar to what’s used in smartphones and electric vehicles. These batteries are popular because they’re efficient, have a long lifespan, and can store a large amount of energy in a relatively small space.

When solar panels produce extra electricity, it can be stored in batteries to use later, when time-of-use rates are high or when your panels aren’t producing. In the event of an outage, the battery can be set to provide backup power to your home. 

Battery systems operate in the background, charging from solar panels (or from the grid). This stored energy provides stability, energy flexibility and backup power controlled through settings in the battery application.

When the electrical grid goes down, the home battery can automatically isolate your house from the grid and start powering your home. This allows you to continue using select appliances and devices until the power comes back on. In fact, homeowners are often unaware that there’s been a power outage in their area. Your house will reconnect to the grid when the battery system recognizes that power has been restored.

It depends! The amount of backup power you need depends on how much energy your home uses. Most people choose an “essential” backup, which keeps things like lights, refrigerators, fans, internet, and power outlets running during an outage. Batteries can also back up other appliances, like heat pumps, air conditioners, or even the whole house, but in some cases these ‘larger’ electric loads will exceed the capacity of the battery system. The final plan for backup will be determined after site survey and during the detailed system design process. Your installer will attempt to provide full home backup, but may be unable to for home with multiple large loads.

The battery installation typically takes one to three days, depending on the size and complexity of the system. Your installer will work with you to schedule the installation.

Customer fees will range from $50-$150 per battery per month. Each customer’s final rate will be based on several factors, including installation complexity, installer costs and customer preference.
