For example, the best solar panels available may have premium efficiencies and warranties, but will typically be more costly. However, depending on the size of the installation, you’ll need to determine whether high-efficiency solar panels that can produce more electricity are worthwhile. Also, your appetite for risk can help determine which solar warranties best fit your needs. These are just a few of the many factors to consider when selecting solar panel equipment.

What rebates and incentives are there in Wisconsin for solar?

The federal Investment Tax Credit has been one of the most reliable and impactful incentives for solar across the U.S. This solar incentive allows you to deduct 30 percent of the total system cost from your federal taxes. For example, a solar energy system installation that costs $15,000 out of pocket will qualify for a tax deduction of $4,500. This advantageous incentive lasts until the end of 2019 - the tax credit amount steps down to 26 percent for 2020 before falling to 22 percent for 2021. The federal ITC is eliminated for residential solar installations after 2021, but commercial solar energy system owners can still deduct 10 percent of a commercial solar system cost from their taxes in 2022 and beyond.

Besides the federal ITC, Wisconsin has additional incentives for going solar that are dependent on your area and utility company. Of note are solar tax incentives, net metering availability, solar access rights, and solar rebates though Focus on Energy.

History of solar policy in Wisconsin

For the Badger State, solar energy is just beginning to become a critical part of its future energy plans. Over the past decade, solar has steadily grown, becoming more accessible for the state’s residents. According to the 2018 SEIA national ranking, Wisconsin only ranks 41st in the nation with a total installed solar capacity of just under 70 megawatts (MW). However, SEIA projects that in five years Wisconsin will catapult all the way to 26th on their national ranking, setting the stage for the development of the solar industry in the near future. While decreasing solar costs and environmental concerns have been critical for the solar industry, Wisconsin’s solar policies are paramount to the growth and increased accessibility of solar in the state.

Wisconsin’s first solar policy came in 1982, when the state implemented Solar Rights Laws. Although the policy doesn’t focus on financial incentives, it recognizes that solar energy usage is a property right, legitimizing the use of the technology throughout the state.

Also in 1982, Wisconsin passed its net metering program for customers that generate electricity with solar systems of up to 20 kilowatts (kW). Net metering programs have been crucial for the solar energy industry nationally as they allow residents to export surplus net energy (NEG) to the electric grid and receive compensation for it on their energy bill. In Wisconsin, most utilities offer their ratepayers compensation for excess solar at the retail rate, rather than the lower wholesale or avoided-cost rate offered in other jurisdictions. Additionally, if a NEG credit in Wisconsin exceeds $25, then the utility must issue a check for the amount to the customer.

In 1999, Wisconsin introduced the state’s renewable portfolio standard (RPS) program, which was one of the first passed in the nation. Across the country, state energy requirements have been imperative to the development of clean energy, and the same is true in the Badger State. Wisconsin’s first RPS goal required utilities to supply 10 percent of their electricity sales from renewable energy by 2015. Although the state has not yet updated this target specifically through the RPS, the current governor just signed an executive order establishing a goal of producing 100% emission-free electricity by 2050.

Also in 1999, Wisconsin created the Focus on Energy Program (FOE), a public benefits fund that provides information, financial assistance, technical assistance and other services for energy efficiency and renewable energy. Funding for the program is supported by surcharges on ratepayer’s electricity bills. For solar specifically, FOE offers a $600 rebate for every kilowatt (kW) of solar power installed on a solar system property, all the way up to 4 kW. Focus on Energy also funds the Renewable Energy Competitive Incentive Program, which began in 2011 to offer grants to support the development of large renewable energy projects.
