Are solar panels worth it for Alliant Energy Wisconsin customers?

Perhaps. With the Federal 26% solar tax credit, and available sales and property tax exemptions, home solar panels are worthy of your consideration as an Alliant Energy customer in Wisconsin. Alliant’s net metering rate also ensures you at least get some credit on your power bill for the excess solar electricity your panels produce. Your electric production can elmiinate your bill each month, but any electricity your panels generate over your monthly usage is credited at a much lower rate.

Does Alliant Energy Wisconsin offer net metering credits for exported solar power?

Alliant Energy does not offer true net metering in Wisconsin, but instead allows generated solar energy to offset your monthly bll up to the amount of kWh you used. What that means is that during summer time when your panels may be generating more energy than your total monthly needs, you'll get paid a lower rate for every kWh more than your total usage. Currently, that rate is $.0331 per kWh.

What incentives, tax credits, and rebates are available to Alliant customers for installing solar?

The biggest financial incentive for solar homeowners is the 30% federal solar tax credit. The tax credit equals 30% of the solar installation costs and directly reduces your federal income tax liability.

Some states and local governments offer additional solar incentives. These incentives include state tax credits, rebates, or performance-based incentives like Solar Renewable Energy Credits (SRECs). The best part is that these local incentives can be used in addition to the federal tax credit!

Here is every incentive you may be eligible for as a Alliant customer:
