An installer’s guide to
Smart Solar Billing in Illinois

Illinois is rolling out new policies that change how homeowners and businesses receive credits for solar energy, bringing in new opportunities and challenges for solar and energy storage projects. Enphase helps installers navigate these updates with specialized tools, ensuring your customers can maximize their savings in the evolving landscape.

As of January 1, 2025, the state has implemented Smart Solar Billing with day-ahead hourly dynamic pricing (DAP) for new solar customers. Shifting from full net metering to supply-only netting for energy exports, Smart Solar Billing encourages self-consumption and reduces reliance on grid exports for solar systems with batteries. The Self-Consumption profile in the Enphase App helps optimize the use of solar energy produced by Enphase Energy Systems for savings on utility bills.

To help Illinois installers make the most of the new policies, Enphase offers tools for proper system configuration and helps meet compliance requirements for storage rebates granted to homeowners with eligible energy storage systems. The Enphase Installer App (formerly known as the Installer Toolkit) has been updated to streamline system configuration for Smart Solar Billing. Solargraf, the Enphase design and proposal platform, also supports design for Illinois systems under Smart Solar Billing and DAP, allowing for detailed cost-benefit analyses and rebate eligibility assessments.
