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.
