To help you determine the best option for you you can use this solar calculator that will weigh different solar options and other renewable energy options.

Why invest in solar panels in Illinois

There are many reasons why Illinois residents are going solar. Before you make the leap it's important to understand all the benefits (or cons) of installing solar for your home.

Reduce your carbon footprint

Solar has roughly 20 times less carbon output than coal-powered energy sources. After three years of use, solar systems are completely carbon neutral and remain so for the duration of their lifespan. 

In short, if you want to reduce your carbon footprint going solar is a great option. 

Lower electricity bills

When you have your own solar system you are putting energy back into the grid. Your utility rewards you by crediting back the value of the energy you put into the grid. For example, if your system generates 2,500 kWh in a month and you use 2,500 kWh in that month you would have a $0 electric bill.

In most cases, if your system generates more energy than you use the credits will roll over to the next month.

Become energy independent

With the right solar system, you could potentially have a self-sufficient power system for your home. This means you don’t have to rely on the grid for energy. If the grid has an outage you could still power your home with your solar system. 

Those who are trying to become energy independent often pair their solar system with a battery. This allows you to store electricity and use it when you need it.

Solar panel incentives in Illinois

Illinois Net Metering

Net metering is a billing mechanism that enables owners of solar panels to sell their excess energy back to the grid in the form of credits. For example, in June your solar panels generate 1,000 kilowatt-hours of energy but you only use 800 kWh you would receive a bill credit for the excess energy you put into the grid. These credits stack, so during the sunny summer months you can rack up substantial credits that will reduce your electric bill in winter when your panels get less sunlight. Net metering greatly improves the financial viability of solar since it enables you to reap the benefits of every kWh of energy you produce, regardless of when you produce it.

Commonwealth Edison (ComEd) offers the best net metering program in Illinois. You can apply for their net metering program and learn more here.

ComEd Commercial Solar Rebates

The Illinois utility ComEd offers business customers significant rebates per kilowatt (kW) if installed solar generation. Systems smaller than 2,000 kW are eligible to receive a rebate of $250 per kW. For more information visit the rebate page on ComEds website.

Illinois Adjustable Block SREC Incentives

As of 2021 the Adjustable Block Program is not longer taking new applicants. In the past this program allowed those with solar panels to receive payment for generating electricity in the form of an SREC for every 1 MWh of electricity generated.

Illinois Federal Solar Tax Credit

Like every other state, new solar panel systems in Illinois are eligible to receive the federal solar tax credit of 26%. This credit is applied on your annual income tax credit.
