Solar power in Tennessee

In 2012, Tennessee's largest solar installation was the 5 MW West Tennessee Solar Farm.

In 2013, Volkswagen opened an 8 MW solar farm at its assembly plant in Chattanooga. The largest solar installations in Tennessee in 2014 were the 20 MW Selmer and 20 MW Mulberry Solar Farms in McNairy County.

In 2015, White Farms, a grain farm in rural Carroll County, installed a 49.725 kW solar array.

A 68.5 MW_(DC) (53 MW_(AC)) solar farm near Millington became the state's largest solar installation in 2019.

Rooftop solar

Photovoltaic panels installed on rooftops is estimated to be capable of producing 23% of all electricity used in Tennessee, with 16,000 MW of solar panels.

Federal law requires net metering upon request, but Tennessee is one of only four states without established policy, meaning that it needs to be negotiated with the utility. A more practical approach is to assume net metering by each utility. Net metering is simply an accounting procedure, and the only requirement is a bi-directional electric meter. Most meters are bi-directional. It is more practical for utilities to discover net metering instead of requiring registration and reporting, just as there is no registration or reporting requirement in connecting an air conditioner, which is instead discovered by utilities. Best practices call for perpetual roll over of kilowatt credits instead of converting to a monetary value.

A 2012 estimate suggested that a typical 5 kW system would pay for itself in about 14 years, and thereafter generate a net savings of $16,622 over the 25 year life of the system.
