Solar Taxes And Rebates

In order to foster solar panel installs at private residences, all a state needs to do is pass legislation with tax and rebate incentives. Connecticut 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 US. Connecticut citizens have the ability to apply a 100% property tax exemption for the installation of private solar, which is as good as it gets. Luckily, consumers in the state have a 100% sales tax exemption for the install of private solar at a home. This is as good as it gets.

State Level Initiatives

Customers searching for electricity options that use renewable sources will find it easier if there are state level legislation that encourage green energy usage. States that have Renewable Portfolio Standards (RPS) have requirements in place for all electricity suppliers who sell electricity in the state. These standards require that a percentage of electricity must be produced using renewable energy. Connecticut has made strong efforts to enact an RPS plan of action that requires at least 25% of electricity output to be fueled by renewable fuel sources. Furthermore, low income solar programs are another way a state can encourage renewable fuels and Connecticut is home to a program that does exactly that.
