Bloomington, IL Solar Panels

Illinois Solar for All (ILSFA) is a state-funded program designed to make solar energy accessible to low- and moderate-income households, renters, nonprofit organizations, and public facilities. To qualify, a household’s gross income must be at or below 80% of the Area Median Income (AMI) for their county. Certain income sources, such as veterans’ benefits and disability payments, may be excluded from the income calculation. Participants pay no upfront costs for installation, and the program guarantees that any ongoing costs or fees do not exceed 50% of the value of the energy the system produces — ensuring real, meaningful savings on energy bills.

ILSFA offers two participation options: a Residential Solar option, where panels are installed directly on your home or property, and a Community Solar option, where you subscribe to a shared solar array in your utility area and receive credits on your energy bill — ideal for renters or those whose roofs aren’t suitable for panels. The program’s annual budget has been significantly expanded to $50 million per year, and more than 10,000 households had enrolled by 2025. For the 2025–2026 period, the total budget stands at $186.3 million across residential and community solar initiatives.

Capacity for single-family and 2–4 unit projects was reached in 2025; interested applicants in Bloomington should contact ILSFA-approved vendors now to prepare for 2026 funding availability. If you use a loan to finance your system, it must have no prepayment penalties and no lien on your home. If you use a lease or PPA, it must save you at least half the retail value of the energy produced. Contact an approved vendor or visit the official ILSFA website to check current availability and begin the application process.

Illinois homeowners who install a solar energy system are fully exempt from any increase in property taxes that would otherwise result from the added value the system brings to their home. Solar installations have been shown to increase home values by 5–10%, which in Illinois — with an average property tax rate of approximately 2.07% — could otherwise result in hundreds of dollars in additional taxes each year. Over the life of a typical solar system, this exemption is estimated to save homeowners approximately $13,351, based on a typical system value of $25,800.

To claim this exemption, homeowners must file a PTAX-330 form (Solar Energy System Assessment Freeze) with their county assessor’s office. This is a one-time filing that locks in your property’s assessed value at its pre-solar level for as long as the system remains on the property. The exemption applies to both rooftop and ground-mounted solar systems and is available statewide to all Illinois homeowners who own their solar system outright or through a loan.

This incentive stacks well with other Illinois solar programs such as Illinois Shines and utility rebates, making it an important long-term financial benefit for residents of Bloomington. There is no income limit or system size cap for this exemption. Contact your local county assessor’s office for the PTAX-330 form and filing instructions specific to your county.

Customers of Ameren Illinois (central and southern Illinois), which serves Bloomington, are eligible for upfront cash rebates through their utility’s Distributed Generation (DG) program. Residential and small commercial customers receive $300 for every kilowatt (kW) of solar capacity installed and $300 for every kilowatt-hour (kWh) of battery storage capacity installed. For example, a 5 kW solar system earns a $1,500 rebate, while a 5 kW solar system paired with a 10 kWh battery earns $4,500.

To qualify, your system must include a smart (grid-interactive) inverter. By enrolling in the Distributed Generation program, you agree to allow the utility to temporarily control your solar inverter or battery during grid stress events — a key requirement for participation. For larger commercial and industrial customers (projects over 150 kW up to 5 MW), the rebate rate is $250/kW for solar and $250/kWh for storage.

These rebates are paid directly to the customer and can be combined with the Illinois Shines SREC program and the property tax exemption for maximum savings. Contact Ameren Illinois at (815) 834-1435 to confirm current program availability, eligibility requirements, and to begin the enrollment process.

The Clean and Reliable Grid Affordability Act (CRGA), signed by Governor Pritzker on January 8, 2026, establishes Illinois’ first Virtual Power Plant (VPP) framework. Under the short-term VPP program, which must launch no later than June 30, 2026, all customer classes — including residential customers — can receive the distributed storage rebate by enrolling in a scheduled-dispatch VPP. A VPP pools energy from small-scale distributed resources like home batteries and solar systems to help balance the grid during peak demand periods, reducing costs for all ratepayers.

Compensation for VPP participation is set by the Illinois Commerce Commission (ICC), with a guaranteed floor of $10 per kilowatt (kW) of average dispatch. This means customers who allow their battery to be dispatched by the utility or an aggregator during grid events will receive ongoing performance payments in addition to any upfront rebates they may have already received. Community renewable generation projects paired with distributed energy resources are required to participate in the VPP program.

A longer-term VPP program is also established under CRGA, launching no later than December 31, 2028, which will expand eligible devices to include smart thermostats and EV batteries, and allow customers to enroll through aggregators or directly with their utility under an approved five-year term rider. Homeowners in Bloomington with existing or planned battery storage systems should monitor announcements from the IPA and ICC for enrollment details as the June 2026 launch approaches.

The Clean and Reliable Grid Affordability Act (CRGA), signed in January 2026, creates the Storage for All program — a new initiative designed to extend the benefits of home battery storage to income-qualified households, nonprofit organizations, and public facilities across Illinois. This program mirrors the equity-focused approach of Illinois Solar for All, ensuring that the financial and resilience benefits of energy storage are not limited to higher-income households.

The Illinois Power Agency (IPA) is also directed under CRGA to conduct an initial large-scale energy storage procurement of at least 1 gigawatt (GW) on or about August 26, 2026, followed by additional procurements targeting 3 GW of storage statewide. This procurement will help drive down costs and expand the availability of storage resources across the state, benefiting both utility-scale and distributed storage markets.

Specific eligibility criteria, application processes, and financial benefit amounts for the Storage for All program are being developed by the IPA and ICC. Income-qualified homeowners and organizations in Bloomington interested in battery storage should monitor the Illinois Power Agency’s website for program announcements, approved vendor lists, and application openings expected in 2026 and 2027.

Illinois transitioned its net metering policy on January 1, 2025, under the Climate and Equitable Jobs Act (CEJA). For all new solar installations interconnected on or after January 1, 2025, excess electricity sent to the grid is credited at the supply-only rate — the wholesale rate utilities pay for electricity from suppliers — rather than the full retail rate. This supply-only credit is less valuable than traditional net metering, meaning new solar customers will see a longer payback period compared to those who installed before the deadline. The exact supply rate varies by utility and changes periodically.

Homeowners in Bloomington whose solar systems were interconnected and operational before January 1, 2025 are fully grandfathered into the previous full retail net metering policy for the lifetime of their system. If you are grandfathered, no action is required — your existing net metering agreement remains in place.

For new solar customers under the supply-only billing model, pairing your solar system with a battery storage system becomes increasingly valuable, as it allows you to store and self-consume excess solar energy rather than export it at the lower supply rate. Programs like the Ameren DG Rebate ($300/kWh) and the new CRGA Virtual Power Plant program can help offset the cost of adding battery storage to maximize your solar investment under the new billing structure.

While the residential federal solar tax credit (Section 25D) expired for systems installed after December 31, 2025, commercial and business entities in Illinois can still claim the Clean Electricity Investment Tax Credit under IRS Section 48E. This credit equals 30% of the total installed cost of a qualifying solar or battery storage system and is available for commercial projects through January 1, 2028. This applies to businesses, nonprofits (via direct pay provisions), and third-party ownership models such as solar leases and Power Purchase Agreements (PPAs).

The Section 48E credit also applies to standalone battery storage systems — not just solar — making it a valuable incentive for commercial customers looking to add energy storage for resilience or demand charge management. Businesses may also benefit from accelerated depreciation through the Modified Accelerated Cost Recovery System (MACRS), which allows the cost of solar and storage equipment to be depreciated over five years, providing additional tax savings on top of the ITC.

Eligibility, credit calculations, and direct pay options can be complex. Commercial property owners, businesses, and nonprofits in Bloomington should consult a qualified tax professional familiar with clean energy tax credits to determine their specific benefit. Additional guidance is available from the IRS and the U.S. Department of Energy.
