Solar power is becoming a popular commodity in Wisconsin, which now ranks 39th in the nation for the number of solar panels installed. In a state where coal accounts for 49 percent of the state’s electricity generation, tax incentives and rebates make solar a viable option for residents looking to reduce the costs of their energy. Find out how to use solar in Wisconsin.

Wisconsin’s Solar
Report Card


To determine a grade for each state, our researchers and solar experts analyzed data on crucial solar-advancement criteria from the following sources:

We determined a rank from one to 10 for each state in each category. We then combined the scores with the following weights and assigned an overall grade for each state. Our goal is to encourage those considering solar for their homes to get a basic understanding of solar potential in their areas and discover the best opportunities for clean energy available.

How Expensive is Electricity in Wisconsin?

Electricity in Wisconsin has become quite expensive, with residential costs averaging $0.15 per kWh in 2019. And that price has steadily increased over the last few years, from $0.14 per kWh in 2015. This continues to be above the national average which hovers at around $0.13 per kWh, according to the U.S. Energy Information Administration. It is no wonder that solar has become more popular in Wisconsin, $238 million invested in this renewable energy source.

Policies & Incentives for Solar Users

Wisconsin residents can take advantage of a wide range of money-saving programs when choosing to go solar. Focus on Energy rebates can help homeowners spend less and get a strong return on investment when purchasing a solar system.
