Illinois, go solar with confidence
Illinois residents: opt for a rooftop solar system with Sunrun for reliable power that keeps up with your needs.
Considering going solar in Illinois?
As Illinois transitions to new solar energy regulations this fall, understanding these changes is crucial for homeowners looking to adapt and benefit. Sunrun, with over 17 years of experience and standing as America’s #1 home solar and battery company, offers tailored solutions designed for Illinois residents' evolving energy needs.
The introduction of the Smart Solar Billing tariff marks a significant shift from traditional net metering to an energy-only supply credit system, creating new opportunities and considerations for Illinois residents. Investing in solar panels and home battery storage allows you to gain greater control over energy costs, shield yourself from ongoing utility rate increases, and decrease your dependency on utility providers. A solar-plus-storage setup enables you to generate your own renewable energy and store excess during peak pricing times—ensuring reliable, cost-effective, and clean energy no matter the grid's condition.
What are the recent changes to net metering for solar customers in Illinois?
In January 2025, Illinois transitioned from traditional retail rate net metering to an energy-only supply credit system. This Smart Solar Billing tariff replaced the old net metering policy, introducing a more dynamic approach that reflects the true benefits of rooftop solar and battery storage. The Smart Solar Billing Tariff aims to compensate homeowners fairly by considering the current energy demands and the time of day when the energy is sent back to the grid.
What is the Smart Solar Billing tariff and how does it differ from traditional net metering?
The Smart Solar Billing tariff is designed to provide a more accurate representation of the benefits that solar systems and battery storage offer to both the grid and homeowners. Unlike traditional net metering that offers a flat credit for surplus energy, the new tariff includes:
A one-time Distributed Generation (DG) Rebate offering $300 per kilowatt for the grid benefits provided by home solar systems.
Dynamic Supply Pricing that varies the value of exported solar energy based on time-of-use rates, aligning compensation with actual energy market conditions.
What is the solar incentive for getting solar power in Illinois?
When you work with Sunrun, we handle all of the available incentives. Vendors directly receive the incentive payment for distributed generation or community solar projects, and vendors then pass along the savings to the consumer or use the incentive payment to lower the purchase or lease price. Illinois offers several incentives to encourage homeowners to adopt solar energy:
Illinois Shines Program: This program provides Solar Renewable Energy Credits (SRECs) to system owners, offering payments for the solar energy produced over 15 years.
Federal Solar Investment Tax Credit (ITC): While not specific to Illinois, this federal incentive allows homeowners to deduct 30% of their solar system costs from their federal taxes. Consult your tax advisor for details.
Net metering: Illinois requires utilities to offer net metering, allowing homeowners to receive credits for excess energy sent back to the grid.
Property tax break: Illinois offers a special assessment for solar energy systems, preventing your property taxes from increasing due to the added value of your solar installation.
Powering Illinois: Easy process. Better technology. Happy customers.
