Why It Works

Key Benefits

Backup Power When You Need It

Keep your lights, refrigerator, medical devices, and Wi-Fi running during outages, whether they last hours or days.

Maximize Your Solar Savings

Store excess solar energy instead of selling it back at low grid rates. Use it in the evening when utility prices are highest.

ComEd Rebate Eligible

Illinois ComEd customers may qualify for a battery rebate through the ComEd Energy Efficiency Program. We handle all the paperwork.

Protection From Rising Rates

Lock in your energy costs and reduce your exposure to future utility rate increases by storing and using your own power.

Step 4Generate & StoreRight-size solar

Step 3: Store What You Generate

Battery storage completes the energy plan. After reducing demand and adding solar, a battery lets you store excess production and use it when the grid is most expensive, or when it's completely unavailable. For homes with EVs or critical loads, it's the final piece of true energy independence.

How much does a home battery cost in Illinois?

Home battery systems typically range from $10,000–$20,000 installed, depending on capacity and brand. When paired with solar, the system qualifies for the 30% federal Investment Tax Credit (ITC). ComEd customers may also qualify for an additional rebate up to $1,000. SPM offers $0 down financing.

How long will a home battery power my house during an outage?

A single battery (10–13 kWh) typically powers essential loads (lights, refrigerator, outlets) for 10–24 hours depending on usage. When paired with solar panels, your battery recharges during the day, providing indefinite backup during extended outages.

Can I add battery storage to my existing solar system?

In most cases, yes. SPM can add battery storage to existing solar systems. The compatibility depends on your current inverter and panels. We will assess your existing system during the free consultation.
