Upcoming Illinois Climate Bank Financial Tools


  • SFA Storage Forgivable Loan

    Target Audience: Residential solar customers participating in the Illinois Solar for All (ISFA) Residential (Small) subprogram, who would benefit from adding storage to their solar systems.  The Illinois Solar for All (ISFA) Residential Solar (Small) subprogram serves single-family and 1-4 unit multifamily buildings. 

    The Storage forgivable loan program will provide up to $7,500 per household to add energy storage to solar photovoltaic systems, especially for households located in low-income or disadvantaged communities. The program will encourage the design of energy storage systems to work in concert with a solar array to provide a resilient source of power for the residence for 12 hours during an extreme heat or cold event or other grid outages . 


    The Illinois Climate Bank will create a fund which can be accessed by Approved Vendors (AVs) and Designees working with residential customers or owners of residential multifamily buildings who are otherwise eligible for ISFA’s Residential (Small) subprogram.  Loans will have forgiveness provisions based on completion of solar installation, quality and completeness, and consumer savings. 


    The Illinois Climate Bank will develop underwriting criteria that focus on the likelihood that the solar project will be installed.  Loans will be made available using a monthly or quarterly open application window, with decisions made on a competitive basis after the window closes. 50% of available funds will be reserved for projects serving eligible households with members age 65 years or older, reliant on electricity-dependent durable medical and assistive equipment and devices, or located in remote locations that are dependent on continuous access to power for life and safety (food, education, health, and safety).  The program will prioritize projects in areas identified as congested or experiencing a high proportion of outages by utility grid congestion and reliability maps.  


    Maximum Award Amount: $7,500  

    Term: 12-18 months 

    Interest rate: Below-market, low-interest rate. 


    Eligibility criteria:  

    Priority will be given to eligible households in which there lives a person reliant on electricity-dependent durable medical and assistive equipment (DME) and devices.  Energy storage must be paired with the deployment of solar for households in low-income or disadvantaged communities. Projects located in utility territories where a distributed generation rebate is available must be designed to qualify for, and must apply for, that rebate, as well as any available tax credits. Projects must provide a resilient source of power for 12 hours continuously during an extreme heat or cold event, or other grid outages. 


    Storage forgivable loans will be available to purchase and install behind-the-meter residential-scale battery storage systems in conjunction with ISFA-incentivized solar systems. Eligible equipment will include: 

    • Batteries; 
    • Smart inverters;
    • Electric panel upgrades, which must be sized for whole home decarbonization; and
    • Meter collars, where found to be more appropriate than a panel upgrade to the project’s technical requirements and cost effective. 
  • SFA Standard Offer Lease-to-Own Loan 

    Target Audience: Approved Vendors (AVs) that need capital to offer residential lease-to-own solar systems that are eligible for incentives under the Illinois Solar for All (ISFA) Low-Income Residential (Small) and (Large) subprograms. 


    The Illinois Climate Bank will launch a standard-offer Lease / Lease-to-own product(s) that would provide simple, easy-to-access financing for smaller and new solar contractors to offer to residential solar customers. The Illinois Climate Bank will create a revolving loan fund which can be accessed by eligible AVs to finance eligible activities. The Illinois Climate Bank will develop underwriting criteria that focus on the likely success of the contractor, as evidenced by their participation with ISFA programs, status as an equity eligible contractor under those programs, participation in other clean-energy-related economic development projects, and similar factors.  This program will enable smaller developers to compete with larger national developers that can facilitate in-house financing.  


    Min. Award Amount: $5,000; Maximum Award Amount: $50,000  

    Interest rate: Below-market. 


    Eligibility:  

    Lease-to-Own Loans will be available to AVs installing solar systems which have received Part 1 approval from the Illinois Commerce Commission under the ISFA Low-Income Residential (Small) and (Large) subprograms, but have not yet been completed and energized.  Because the US EPA definition of an eligible multifamily building1 differs from the ISFA program definition, multifamily projects will be screened and federal funds offered only to those that are eligible under the federal definition. Eligible AVs must have their principal office in Illinois and be very small businesses having fewer than 10 full-time employees. 


    Projects must be eligible for ILSFA residential program, or otherwise eligible for Illinois Shines incentives and benefit a household in a low-income or disadvantaged community.
