Federal Solar Tax Credit

How the ITC Works
The federal Investment Tax Credit (ITC) offers a significant incentive for solar energy systems, providing a credit of 30% of the total installation costs. To be eligible, systems must be placed in service between 2022-2032, with the credit stepping down to 26% in 2033 and 22% in 2034. Homeowners and businesses can claim the credit by filing IRS Form 5695 and Form 3468, respectively, with their federal tax returns. There is no cap on the credit amount, and any excess credit can be carried forward to future tax years. The ITC applies to both purchased and leased systems, making solar accessible to a wider range of Illinois residents and businesses. By reducing the upfront cost of going solar, the ITC plays a crucial role in making clean energy solutions more affordable and attractive for those looking to save on energy expenses while reducing their environmental impact.
ITC Timeline
The federal Investment Tax Credit (ITC) for solar energy systems is currently set at 30% of the total installation cost through 2032. This means that homeowners and businesses in Illinois can deduct 30% of their solar investment from their federal taxes. However, the ITC is scheduled to step down to 26% in 2033 and 22% in 2034 before phasing out completely for residential systems in 2035. Commercial and utility-scale projects will still be eligible for a permanent 10% credit from 2035 onwards. To maximize the financial benefits of going solar, it’s crucial to take advantage of the ITC while it remains at its highest level.
Illinois Shines Program
How Illinois Shines Works
The Illinois Shines program, also known as the Adjustable Block Program, is designed to support the development of new solar photovoltaic projects in the state. It offers incentives in the form of Renewable Energy Credits (RECs) to homeowners, businesses, and community solar developers who install solar panels. The value of these RECs is set through a competitive procurement process, providing a transparent and stable revenue stream for solar projects.
To participate in Illinois Shines, solar projects must meet specific requirements, such as using qualified equipment and installers, and adhering to applicable codes and standards. Homeowners and businesses can either own their solar panels directly or subscribe to a community solar project to receive the benefits of clean energy without installing panels on their own property.
The program is divided into three categories: Small Distributed Generation for residential and small commercial projects, Large Distributed Generation for larger commercial and industrial installations, and Community Solar for projects that serve multiple subscribers. Each category has its own set of incentives and capacity allocations, ensuring a diverse mix of solar projects across the state. By offering these incentives, Illinois Shines aims to make solar energy more accessible and affordable for all Illinoisans while driving job creation and economic growth in the state’s solar industry.

Solar Renewable Energy Credits (SRECs)
Solar Renewable Energy Credits (SRECs) play a crucial role in the Illinois Shines program, providing an additional revenue stream for solar system owners. SRECs are tradable certificates representing the environmental attributes of solar energy, with one SREC issued for each megawatt-hour (MWh) of electricity generated by a solar system. Under Illinois Shines, the Illinois Power Agency purchases SRECs from qualifying solar projects through 15-year contracts, offering a reliable and long-term incentive for going solar.
The value of SRECs in Illinois is determined through a competitive procurement process, with prices varying based on project size and type. As of 2023, the average SREC price for small-scale systems (up to 10 kW) is around $72 per MWh, while larger systems can earn between $60 and $85 per MWh. By selling SRECs, solar system owners can offset a significant portion of their installation costs over time, making solar investment more attractive and cost-effective.
To be eligible for SREC payments, solar systems must be located in Illinois, meet applicable technical and performance standards, and comply with consumer protection requirements. Participating in the SREC market through Illinois Shines not only benefits individual solar owners but also supports the state’s ambitious renewable energy goals and helps drive the growth of the local solar industry.
Net Metering in Illinois
Net metering in Illinois allows solar system owners to send excess electricity generated by their panels back to the grid in exchange for credits on their utility bills. When a solar system produces more energy than the property consumes, the surplus is fed into the grid, and the owner’s meter literally runs backward. Conversely, when the property requires more electricity than the solar panels are generating, it draws power from the grid, and the meter moves forward. At the end of each billing cycle, the net usage is calculated, and the customer is billed for the difference or credited for any excess production.
This policy is incredibly beneficial for solar owners in Illinois, as it essentially allows them to use the grid as a battery storage system without having to invest in expensive on-site storage solutions. It also helps maximize the value of their solar investment by ensuring they receive fair compensation for the clean energy they contribute to the grid. Net metering, combined with other solar incentives and financing options, makes going solar in Illinois an attractive and cost-effective proposition for many homeowners and businesses.
Solar for All Program

Eligibility Requirements
To qualify for the Illinois Solar for All program, participants must have a household income at or below 80% of the Area Median Income (AMI). This includes both homeowners and renters who pay their own electric bills. Eligible properties include single-family homes, multifamily buildings, and community solar projects serving low-income subscribers. Non-profit organizations and public facilities that primarily serve low-income communities may also qualify. The program aims to make solar accessible and affordable for underserved populations, promoting equitable access to clean energy benefits. Qualified participants can receive significant incentives and support to reduce the upfront cost of going solar.
How to Apply
To apply for the Solar for All program, first determine your eligibility by checking the income requirements on the Illinois Solar for All website. If eligible, find an approved vendor in your area using the vendor directory. Contact the vendor to discuss your solar project and gather necessary documentation, such as proof of income and property ownership. The vendor will then submit your application to the program administrator for approval. Once approved, the vendor will install your solar system at no upfront cost. After installation, you’ll receive credits on your utility bill for the energy produced, reducing your energy costs while supporting clean energy in Illinois.
Conclusion
In conclusion, Illinois offers a robust set of solar incentives in 2023 that make going solar more affordable and accessible than ever before. From the federal solar tax credit to state-level programs like Illinois Shines and Solar for All, homeowners and businesses have a range of options to reduce the upfront cost of installing solar panels. As solar technology continues to improve and costs decline, these incentives are expected to drive significant growth in Illinois’ solar market in the coming years. By going solar, Illinois residents can not only save money on their energy bills but also contribute to a cleaner, more sustainable future for the state. With expert guidance from local solar installers, now is an excellent time to explore the benefits of solar energy and take advantage of the many incentives available in Illinois.
