Federal Solar Incentives: The Investment Tax Credit (ITC)
The most significant financial incentive for homeowners nationwide is the federal Solar Investment Tax Credit (ITC). This is a dollar-for-dollar credit that directly reduces the amount of federal income tax you owe.
- Credit Amount: For systems installed between 2022 and 2032, the ITC allows you to claim 30% of the total cost of your solar energy system.
- Impact: On a $20,000 solar system, the 30% ITC provides a $6,000 credit, effectively lowering your net cost to just $14,000.
Wisconsin’s State & Local Solar Incentives
Wisconsin’s primary incentive is a direct rebate from the statewide Focus on Energy program, complemented by a property tax exemption.
Name of Incentive | Type | Description | Key Details | Estimated Cash Value |
Federal Solar Tax Credit | Federal Tax Credit | A 30% credit on the total cost of your system against your federal income taxes. | The most significant financial incentive available. | $4,500 – $8,100 |
Focus on Energy Rebate | State Rebate | A one-time cash rebate of $500 for homeowners who install a solar PV system. | A direct, upfront reduction of your system cost. | $500 |
Property Tax Exemption | State Tax Exemption | A 100% exemption on the value added to your home by a solar system. | Your property taxes will not increase. | Varies (Saves hundreds) |
Net Metering | Utility Bill Credit | Earn credits on your utility bill for excess electricity your system sends to the grid. | Maximizes the value of every kWh you produce. | Varies |
Focus on Energy – Renewable Energy Rewards
- How it Works: Focus on Energy, Wisconsin’s statewide energy efficiency and renewable resource program, offers a direct, upfront cash rebate to homeowners who install a qualifying solar PV system. The current rebate amount is $500. The application is typically handled by your installer, who must be a registered Focus on Energy Trade Ally.
- Impact: This is a powerful, direct reduction in your system’s price. Unlike a tax credit, this is cash back that lowers your initial investment immediately.
Wisconsin Solar Property Tax Exemption
- How it Works: Wisconsin law provides a 100% property tax exemption for the value added to a home by a solar energy system.
- Impact: This is a significant long-term benefit that saves you hundreds of dollars every year for the life of your system.
Understanding Net Metering in Wisconsin
- How it Works: Net metering is a critical policy that ensures you get value for every kWh your system produces. When your panels generate more power than you are using, the excess is sent to the grid, and you receive a credit on your bill from your utility (Alliant, We Energies, etc.).
- Impact: The value of these credits varies by utility. Finding an installer who understands your specific utility’s net metering rules is crucial to maximizing your solar savings.

How To Get Solar With No Upfront Cost
For many homeowners, the ability to go solar without a large upfront investment is key. Financing options like $0-down solar loans are especially powerful because they allow you to own your system and claim the valuable 30% federal tax credit and the state rebate. This makes solar accessible even without a large initial capital outlay.
