Are solar panels worth it for Commonwealth Edison (Com Ed) customers?

The answer is, absolutely. With the Illinois Shines block grant program, and Com Ed’s strong net metering policy, solar panels make a whole bunch of sense in Illinois, especially for Com Ed customers! Com Ed’s net metering ensures you get credited on your power bill for the excess solar electricity your panels produce. Your credits roll over to the next month’s bill and are reset annually.

Does Commonwealth Edison (Com Ed) offer net metering credits for exported solar power?

Yes, Commonwealth Edison (Com Ed) offers net metering credits.

Under the Commonwealth Edison (Com Ed) net metering program, solar panels will first send energy to your home. Any excess solar energy is sent to the grid and purchased in the form of a bill credit. The credit value is determined by the Tri-Party Net Metering Power Purchase Agreement. KUA customers are billed for all of the electric energy delivered to them by the company.

What incentives, tax credits, and rebates are available to ComEd customers for installing solar?

The biggest financial incentive for solar homeowners is the 30% federal solar tax credit. The tax credit equals 30% of the solar installation costs and directly reduces your federal income tax liability.

Some states and local governments offer additional solar incentives. These incentives include state tax credits, rebates, or performance-based incentives like Solar Renewable Energy Credits (SRECs). The best part is that these local incentives can be used in addition to the federal tax credit!

Here is every incentive you may be eligible for as a ComEd customer:
