Step‑by‑Step Guide to Applying for Incentives

Labor Day

Step 1 – Request an Estimate

Request an estimate from Northwind Solar. We assess your energy needs, site layout, and project goals to determine which incentives may apply to your home, business, farm, or organization. Understanding incentives early lets us incorporate them into your project planning and budget.

Step 2 – Documentation and Applications

We guide you through collecting utility bills, property information, and installation estimates. For Focus on Energy rebates and other local incentives, our team submits the applications directly to program administrators, reducing hassle and helping ensure compliance with all requirements.

Step 3 – Installation and Verification

Once approved for incentives, Northwind Solar designs and installs your system to high quality standards. After installation, we verify that your system meets all program requirements, complete any inspections, and finalize documentation needed for rebate disbursement and tax credit claims.

Step 4 – Ongoing Support and New Opportunities

After your system is up and running, we provide ongoing support and monitoring. We can answer questions about continued eligibility for incentives or new programs that may become available, helping you enjoy the full financial and environmental benefits of solar energy over time, and for project expansions.

10% Energy Community Bonus Credit

Some Central Wisconsin businesses and nonprofits may qualify for an extra 10% federal solar credit through the Energy Community Bonus. Energy Communities are federally designated areas affected by coal mine closures or retired coal plants, and many local communities fall within these zones.

Commercial, nonprofit, municipal, and other tax‑exempt solar projects located in designated Energy Communities may be eligible for an additional 10% credit on top of the standard federal solar incentive, potentially increasing the total credit from 30% to 40% of eligible project costs.

For many organizations, that extra 10% can make solar and battery storage more financially attractive by lowering upfront project costs, improving long‑term ROI, and reducing exposure to rising utility rates.

Common Central Wisconsin areas to review include Wausau, Mosinee, Stevens Point, Plover, Menasha, and nearby communities.
