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 upcoming changes to net metering for solar customers in Illinois?

In January 2025, Illinois will transition from traditional retail rate net metering to an energy-only supply credit system. The new Smart Solar Billing tariff will replace the old system, introducing a more dynamic approach that reflects the true benefits of rooftop solar and battery storage. This new system 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 over 25 years.

  • 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.

FAQs

The cost of installing solar panels in Illinois varies depending on factors such as system size, equipment quality, and installation complexity. As of 2024, prices of solar systems have decreased by 43% in the last 10 years [1].

However, when considering the cost, it's important to factor in the long-term savings as well as the potential incentives. State and federal incentives can be applied to the cost of your solar system project. In addition, solar installations typically increase property values, which can be beneficial if you plan to sell your home in the future. Installing solar panels with various financing solutions like loans, leases, upfront payments, or subscriptions can also make solar more affordable.

Illinois homeowners can reap numerous benefits from installing solar panels and battery systems. These systems offer increased energy independence, allowing you to generate and store your own electricity, which reduces reliance on the grid and provides power during outages. Financially, solar installations can lead to significant savings by offering reliability in monthly utility bills and protecting against future rate increases. They also typically increase property values, offering an additional financial benefit. 

From an environmental perspective, solar energy helps reduce your carbon footprint, contributing to a more sustainable future for Illinois. The state offers various incentives for solar adoption, including the Illinois Shines program and property tax breaks, which, combined with a federal solar tax credit, can significantly reduce solar system installation costs. Solar panels with battery storage can also optimize energy use during peak demand periods, potentially leading to a more stable electricity system for all residents. Additionally, you're contributing to job growth in the state's renewable energy sector by supporting the solar industry. Solar systems are adaptable to various property types and require minimal maintenance, providing a hassle-free source of energy for decades. As policies and technologies continue to evolve, the benefits of a solar panel and battery system in Illinois are likely to increase, making it an increasingly attractive option for homeowners looking to take control of their energy future.

Now is the ideal time to invest in renewable energy with a residential solar system for Illinois homeowners:

  • Rising electricity rates: Illinois has seen steady increases in electricity rates over the past decade, with further increases expected.

  • Strong incentives: The combination of state and federal incentives can dramatically reduce solar installation costs. We pass along the savings from state incentives to you at a low monthly rate.
