Your Guide to Community Solar Programs in Illinois

How Much Can I Save by Joining an Illinois Community Solar Program?

Savings usually come through bill credits and discounted subscription structures. That is one reason community solar in Illinois appeals to people who want simpler savings without owning a full solar system.

The exact savings on your electricity bill vary depending on the specific community solar program and the user’s energy consumption, but generally range from 5% to 10% annual savings. If you qualify as a low to moderate income resident then your savings gets bumped to 20% annually.

Important Fine Print Before you Subscribe

Here is the part nobody puts on a movie poster, but it matters.

• Your savings can vary by project and utility billing terms. Community solar savings typically fall in the 10% to 20% range, not one flat number for everyone.
• You usually must live in the same utility territory as the solar project. Your share needs to match the local utility rules, so not every solar farm in Illinois is available to every resident.
• Billing details matter. Some programs use a single utility bill with built-in credits, while others may involve separate invoicing. Always check the enrollment terms.
• Contract terms may differ. DOE’s community solar consumer guidance emphasizes plain-language disclosures and says strong community solar programs should avoid sign-up, exit, and termination fees.

How to Know if Community Solar Is Right for You

Deciding if community solar is the right choice involves considering several factors. If you live in Illinois and lack a suitable roof for solar panels, or if you’re a renter, community solar offers a practical solution to participate in renewable energy. It’s also worth considering if you’re looking for ways to lower your electricity bills while supporting local renewable energy projects. Comparing IL community solar providers and plans is necessary to find the best fit for your energy needs and financial goals.

What Is the Difference Between Community Solar and Green Energy Plans?

While both community solar and green energy plans aim to increase the use of renewable resources, there are key differences. Community Solar in Illinois focuses on sharing the output of a local solar farm among community members, directly connecting consumers with their energy source. Green energy plans, on the other hand, may source electricity from a variety of renewable sources, which may not necessarily support local jobs or energy independence.

What is the Difference Between Community Solar and Rooftop?

Rooftop solar systems require homeownership and a significant upfront investment. They offer personal energy production and the potential for increased property value. In contrast, community solar is an accessible alternative that doesn’t require property ownership, upfront costs, or suitable roofing conditions. It is more inclusive and appeals to a broader range of people.

With community solar, participants share the energy production, contributing to sustainability without the logistical and financial commitments of rooftop installations. The decision between the two options depends on individual circumstances, such as financial readiness, property suitability, and personal preferences for energy independence or community participation. Both choices promise to use renewable energy but cater to different needs.

Leading Illinois Solar Programs

The Illinois Power Agency (IPA) and the Illinois Commerce Commission (ICC) oversee the state’s two primary incentive paths:

Illinois Shines Program

The Illinois Shines program has established itself as a cornerstone of the state’s green economy, deploying over 4,190 Megawatts (MW) of solar capacity across more than 116,000 approved applications spanning all 102 Illinois counties. As a state-administered solar incentive initiative managed by the Illinois Power Agency (IPA) the program aims to make clean energy affordable and accessible for all residents.

Rather than paying consumers directly, the program provides financial incentives through the purchase of Renewable Energy Credits (RECs). When a solar project generates electricity, it earns RECs representing the environmental value of that clean power. State utilities purchase these RECs to meet Illinois’ aggressive clean energy mandates. The financial value of these RECs is passed directly to consumers by program-approved vendors, driving down the overall cost of going solar.

To date, over 102,000 energized projects have brought clean energy and financial benefits to more than 489,000 homes and businesses.

Eligibility: Who Can Participate?

The Illinois Shines program boasts broad, inclusive eligibility requirements designed to help the state reach its goal of 100% clean energy by 2050. Eligible participants include:

• All Illinois Residents: Both homeowners and renters who receive electric service from a regulated utility (such as ComEd or Ameren) can subscribe to a community solar project.
• Commercial and Industrial Customers: Businesses of all sizes can participate to offset their operational carbon footprint and lower energy overhead.
• Public Schools: The program features a dedicated “Public Schools” category designed to maximize financial and educational savings for schools located in communities traditionally excluded from the energy sector.
• Non-Profits and Public Facilities: Municipal buildings, places of worship, and community centers are fully eligible.

Illinois Solar for All

Illinois Solar for All (ILSFA) is designed specifically to bring the financial and environmental benefits of clean energy to low-income households, environmental justice communities, and qualified non-profit organizations.

Administered on behalf of the Illinois Power Agency, ILSFA heavily incentivizes solar development to ensure that participants bypass financial barriers and see maximum returns on their utility bills.

This program has immense impact to low-income residents. Single-family homeowners participating in the residential program save roughly $1,000 annually on their electric bills.

How It Works & Consumer Protections

• Guaranteed Savings: Unlike standard solar programs where savings fluctuate, ILSFA mandates that participating income-eligible residents cannot spend more than 50% of the value of the energy generated on any ongoing fees or subscription costs. This structural safeguard guarantees a massive return on investment.
• No Upfront Costs: Both the residential and community solar sub-programs are structured so that qualified participants face $0 in upfront costs to switch to clean energy.
• Vetted Protection: All projects are built and managed by highly scrutinized “Approved Vendors” who must meet rigorous state requirements for consumer protection, financial transparency, and quality workmanship.

Program Eligibility

To participate in Illinois Solar for All, residents must meet specific criteria outlined by the state:

• Income Thresholds: Income-eligible households are defined as those whose gross household income does not exceed 80% of the Area Median Income (AMI). These limits are updated annually and vary depending on your county and household size.
• Environmental Justice Communities: A minimum of 25% of the program’s incentives are explicitly reserved for projects built within historically marginalized or pollution-burdened neighborhoods designated as Environmental Justice Communities.
• Property Ownership Status: The program is fully inclusive. Eligible homeowners can apply for on-site residential rooftop solar, while renters and condo owners can seamlessly access the program through specialized ILSFA Community Solar subscriptions.

History of Community Solar in Illinois

Community solar in Illinois began gaining traction after the 2016 passage of the Future Energy Jobs Act (FEJA), which created incentives for renewable energy developers. This law led to the state’s first wave of community solar projects.

Then in 2021, the Climate and Equitable Jobs Act (CEJA) expanded funding and long-term support for renewables, unlocking a second, much larger wave of community solar construction. CEJA also prioritized equitable access, reserving a portion of community solar capacity for low-income and environmental justice communities.

Today, Illinois is considered a national leader in community solar deployment, with more projects under development and waitlists opening regularly.

Quick Facts about Community Solar in Illinois

Here are a few standout data points showing how impactful community solar has become in the state:

• Illinois is among the top 5 fastest-growing community solar markets in the U.S., thanks to strong incentives under the Climate and Equitable Jobs Act (CEJA).
• More than 12,000 Illinois households are already subscribed to community solar projects statewide.
• Community solar projects in Illinois have helped avoid tens of thousands of metric tons of CO₂ emissions annually, equivalent to removing thousands of cars from the road.
• The state has awarded enough project capacity to support hundreds of megawatts of new community solar development, with more projects launching each year.

What to Expect With Your New Solar Bills

In Illinois, there is what’s called Universal Consolidated Billing (UCB). This means that, as a community solar subscriber, you simply receive your regular utility bill from ComEd or Ameren and it’ll just have an additional section or line item showing your solar farm credits and how much they’re offsetting your total cost. UCB is the preferred method within the industry and makes it seamless for you, as the subscriber. That’s because you don’t need to do anything differently.
