Solar Installation Rebates
The City of Naperville Electric Utility is offering up rebates from $1,000 to $3,000, based on the size of the system, and a 3-year peak kW to homeowners who purchase and install either a roof-mounted solar energy system or a solar water heating system. The rebates are for residential solar installations that are installed and passing final inspection on or after January 1, 2021. Completed applications must be submitted within six months of passing the final inspection. Learn more about the program in the application.
The City of Naperville is committed to working to improve solar market conditions, making it faster, easier and more affordable for our residents and businesses to install solar energy systems. We formally support the following goals and will work to achieve them both in our own community and with collaboration throughout the region. These high-level energy goals are:
- Advance renewable energy
- Enact policies that support clean energy
- Engage the community in clean energy practices
In order to measure progress along the way, we will track key metrics related to solar energy deployment, such as the number and location of solar installations and their capacity. This action is consistent with our commitment to transparency, open data, and sustainability reporting expectations established by our local Sustainability Plan.
Solar Installation Checklist
Before installing solar panels, here is a checklist that will help guide you through the process.
Roof Top Solar - Re-Roofing, system modifications or additions.
In all cases, a City of Naperville Building Permit will be required to re-install any system that has been removed due to any re-roofing project. Additionally, any modification to an existing system will require a City of Naperville Building Permit. Please view the solar checklist for permit information.
Solar Panel Guidelines include:
- Solar Installation Application Packet that includes information about:
- Utility Connection Standards
- Net Metering: Customers with solar panels installed can participate in Net Metering, which is an arrangement by which excess energy generated by a renewable energy system is distributed back to the grid. Customers will see a credit on their bill.
- Solar Compliance Form
- Residential Load Calculation
