There are many opportunities to help you offset the out-of-pocket costs to install a solar generating system. One of the best ways to understand costs and incentives is to use a tool to help you calculate your solar potential. ComEd's
solar calculator helps you assess your rooftop solar potential by combining your historical usage data with solar data in your area to provide a personalized evaluation for your property, including any rebates and credits.
Federal and state incentives are offered to ComEd customers who choose to go solar. To learn about any incentives you may qualify for, launch our
RECs are certificates that are created when a renewable energy generating facility produces energy. RECs may be sold to the utility for meeting the State's Renewable Portfolio Standards.
Residential: REC’s are a state incentive, whose value is equal to the solar energy you produce over 15 years times the price set by the Illinois Power Agency for REC’s. For your system, the value is 7.1 cents/kWh produced, which is paid in year one. Please note this is an incentive which is subject to tax.
Commercial: REC’s are a state incentive, whose value is equal to the solar energy you produce over 15 years times the price set by the Illinois Power Agency for REC’s. For commercial customers, this is paid out over 5 years, and the REC value varies based on the size of the solar system. Please note this is an incentive which is subject to tax.
Taxpayers can claim a Federal Income Tax Credit (FITC) of 26% for qualified expenditures on a solar system that provides electricity to their residence (owned and lived in by the taxpayer). For more information, see

When you have a solar system and are being billed for net metering, you are charged only for the net amount of energy you use during each billing period (i.e., the amount of energy we deliver to you minus the excess amount you send back to the smart grid). And, if you send more energy to the grid than we deliver, you can receive credits on your bill. This program allows you to make full use of your own solar energy system, giving you more control over your energy costs.
Solar energy systems of customers who want to participate in net metering are limited in capacity size so that they generate no more than 110% of the customer's prior 12 months of electricity usage. If the customer does not have a full year's worth of usage, ComEd will use the class average amount for a proxy of usage for similar systems.
