What is Solar + Battery Storage and How Does it Work?

Solar and battery storage offers a unique way to maximize your solar system’s grid independence and protect yourself from the dangers of power outages. With solar and batteries paired, you can charge the batteries with excess solar generation during the day, and power your home from that stored energy during the night.

Benefits:

  • Batteries can be configured to provide home backup in times of need, engage in energy arbitrage to maximize hourly pricing peaks and valleys, or a combination of both.
  • Power critical loads such as perishables, kitchen utilities and internet when the power goes out with partial home backup.
  • Maximize your solar systems performance with full battery backup storing all excess generation for on site use.

Incentives:

  • Both stand-alone batteries and solar paired batteries qualify for the 30% Federal Tax Credits and all applicable IRA adders
  • Batteries qualify for the ComEd Storage Rebate, offering $300/kWh of storage capacity
  • The ComEd Storage Rebate is available even to legacy net metering customers who are looking to add batteries to their existing home solar system.

FAQs

Can I go off grid? We are very fortunate to be connected to a grid, so we want to utilize it. Almost all systems in our area our grid tied. To go fully “off grid” is a very expensive process and truly utilized for situations where grid connection is not in the area.

Can I charge the battery during the day and use the power at night? Technically, yes. However, we operate mainly on fixed rate bill, so this function is not typically used in our area.

Do I backup my whole house or just a critical loads panel? We can offer both, but in most cases, you just need to back up the most critical loads to get you through an outage. Backing up an entire house requires a larger investment.

Can I back up my A/C unit and other large electrical loads? If you were to back up large electric loads, such as HVAC systems, the battery will deplete rather quickly. That said, we normally do not recommend backing up non-critical loads such as HVAC.
