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.

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.
