Solar Taxes And Rebates

When it comes to stimulating home installs of solar, one of the best uses of government resources is tax breaks and rebates for solar installs. Illinois currently does not offer a state tax credit for solar panel installation at a private residence. Residents in the state enjoy rebates for private solar installs of over $500. This is the highest amount we’ve seen in the nation. Unfortunately, residents in the state are only offered some optional tax exemptions for what they spend on solar installation. There is currently no sales tax exemption for consumers who install solar.

State Level Initiatives

Policies drawn up at the state level determine whether customers who are seeking renewable energy sources can easily find alternatives. Many states require green fuel types to be a percentage of the fuel used for electricity production. These guidelines are known as Renewable Portfolio Standards (RPS). While further enhancements could be made, Illinois requires for 1-15% of electric generation to come from renewable fuel sources. In addition, low income solar programs are another way a state can encourage renewable fuel types and the state of Illinois is home to a program that does exactly that.
