Alliant Energy® Community Solar – Janesville for business customers

Make the transition to affordable clean energy.

Community solar offers clean, local energy for your business that can offset a portion of your electric bill. It won’t require the installation of solar panels on your property and will set your business apart as a leader in sustainability.

When you subscribe to the Alliant Energy® Community Solar program, your business supports efforts to create a healthier environment and reduce dependence on fossil fuels. As a community-funded project, Alliant Energy's Community Solar program depends on your support. When you enroll, we’ll create informational materials to recognize your support and inform your employees and customers about our program.

Get started

Community solar is available to Wisconsin electric customers on a first-come, first served basis. Participation is easy.

Step 1

Use this calculator to determine the number of 250-watt solar energy-producing blocks you need to meet your green goals. You can purchase a subscription equal to 10%, 25%, 50% and even up to 100% of your energy use. 

Step 2

Sign up. Once you determine the number of solar blocks you need, complete the Alliant Energy® Community Solar subscriber form.

Step 3

Pay for blocks upfront or in 12-month installments at no extra cost. Each 250-watt block costs $337. There is also a one-time $25 administration fee.  

Step 4

Receive a bill credit each month for up to 20 years. The credit is based on solar production. Sunnier days mean a larger credit. Bill credits begin once you pay the upfront subscription fee in full and the solar site is operational. See estimated bill credits below.
