Buffalo Grove Solar Incentives, Tax Credits, and Rebates

Illinois solar incentives and federal tax credits can cover 60% or more of the purchase price of solar for homeowners in Buffalo Grove:

Illinois Shines Solar Incentive

Illinois Shines provides Buffalo Grove homeowners with up-front payments for the renewable energy that your system is expected to produce in the form of SRECS (Solar Renewable Energy Credits). The value of these credits changes over time, but can be worth over 30% of the cost of your system!

Federal Solar Tax Credit

Buffalo Grove homeowners can take advantage of the 30% federal solar tax credit. This credit is a dollar-for-dollar reduction in the amount of federal income tax you would typically owe.



ComEd Net Metering

With net metering, your utility gives you a credit for any excess energy that your system produces. ComEd, which covers all of Buffalo Grove, provides one-to-one net metering; this means that customers will be compensated for the full value of their excess production.

ComEd Solar Rebate

ComEd began offering a rebate to residential solar customers in 2023 called the Renewable Energy Distributed Generation Rebate, worth $300 per kW DC of their solar capacity. This rebate comes with some tradeoffs, and our detailed analysis suggests that the ComEd solar rebate is not a good deal for the typical customer.

ComEd EV Charger Rebate

ComEd began offering an EV charger rebate that can cover up to $3,750! Buffalo Grove residents looking to install an EV charger can benefit from this rebate and potentially cover the entire cost of their EV charger installation. Learn more about Certasun’s EV charger installations.
