What is Alliant Energy® Community Solar?

You can power your home using solar energy without installing or owning your own solar generating system. This is a great option if you rent your home or apartment. With Alliant Energy® Community Solar, you can buy shares of renewable energy for your home, generated from solar panels in a nearby community.

What's a share?

To understand what a share is, think about how community supported agriculture (CSA) works. When you buy into a CSA, you pay the farmer in advance, and then you get a portion of the fruits and veggies grown during the season. Community solar is similar.

When you buy a share of Alliant Energy® Community Solar, you purchase a portion of the energy that is generated by the solar array. Each share offsets about 5% of average residential monthly usage. You can buy more than one share, up to 100% of your energy use.

Can I lower my bill on Alliant Energy® Community Solar?

You will receive a bill credit for a percentage of the energy output for the solar array. The bill credit for one share will average $24 to $36 annually and will vary depending on solar production.

  • Iowa customers’ monthly credit = $0.059 per kWh (residential and commercial)
  • Wisconsin residential customers’ monthly credit = $0.063 per kWh

How much does it cost?

  • Iowa customers: $35 enrollment fee and one-time, upfront payment of approximately $350 per share
  • Wisconsin customers: $25 enrollment fee and one-time, upfront payment of approximately $300 per share

You can buy more than one share, up to 100% of your usage.
