Solar power in Tennessee is capable of producing much of the state's electricity; however, the industry remains in early stages in the state. With 129 MW of solar power in 2015, Tennessee ranked 20th among states for installed solar capacity.

The largest solar installations in Tennessee are the 20 MW Selmer and 20 MW Mulberry Solar Farms in McNairy County, both built in 2014. In 2013, Volkswagen opened an 8 MW solar farm at its assembly plant in Chattanooga. In 2012, Tennessee's largest solar installation was the 5 MW West Tennessee Solar Farm.

A 68.5 MW(DC) (53 MW(AC)) solar farm is under construction near Millington with expected completion in 2017.

I am claiming the 26% Federal Tax Credit (ends 2022) i

When you install a solar system, 26% of your project expenses apply toward a credit to offset any taxes you owe that year. This federal tax credit is a major incentive to go solar, but it is going to be phased out by 2024.

To be eligible to claim this credit, you must owe federal taxes.
