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.[http://www.seia.org/state-solar-policy/tennessee Tennessee fact sheet], SEIA, accessed June 4, 2016
In 2012, Tennessee's largest solar installation was the 5 MW West Tennessee Solar Farm.[http://solarfarm.tennessee.edu/ West Tennessee Solar Farm]
In 2013, Volkswagen opened an 8 MW solar farm at its assembly plant in Chattanooga.[https://www.usatoday.com/story/money/business/2013/01/23/tenn-volkswagen-plant-solar/1858937/ Volkswagen powers up 33-acre solar park in Tenn.],
Erik Schelzig, Associated Press, USA Today, January 23, 2013 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.{{Cite web |last=Smith |first=Kathy |date=2015-08-14 |title=USDA RD Assists White Farms with Solar Array Purchase |url=https://www.rd.usda.gov/newsroom/success-stories/usda-rd-assists-white-farms-solar-array-purchase |access-date=2022-08-13 |website=USDA Rural Development |language=en}}
A 68.5 MW(DC) (53 MW(AC)) solar farm near Millington became the state's largest solar installation in 2019.[http://www.commercialappeal.com/news/government/states-largest-solar-array-planned-for-millington-30d9964f-2722-2a4e-e053-0100007fd548-376260241.html State’s largest solar array planned for Millington], Tom Charlier, The Commercial Appeal, April 19, 2016{{Cite web|last=Clark|first=Tish|date=April 23, 2019|title=Millington goes green with the largest solar farm in Tennessee|url=https://www.localmemphis.com/article/news/local/millington-goes-green-with-the-largest-solar-farm-in-tennessee/522-0baba4bd-44af-4a6f-860e-7a4f62e8f613|access-date=2021-12-19|website=ABC 24, localmemphis.com|language=en-US}}{{Cite web|last=Gordon|first=Philip|date=2020-06-20|title=Counting sheep at Tennessee's 53MW Millington Solar Farm|url=https://www.smart-energy.com/regional-news/north-america/counting-sheep-at-tennessees-53mw-millington-solar-farm/|access-date=2021-12-19|website=Smart Energy International|language=en-ZA}}
Rooftop solar

Photovoltaic panels installed on rooftops is estimated to be capable of producing 23% of all electricity used in Tennessee,[http://green.blogs.nytimes.com/2009/10/30/report-argues-for-a-de-centralized-system-of-renewable-power-generation/ Report Argues for a Decentralized System of Renewable Power Generation] with 16,000 MW of solar panels.[http://www.nrel.gov/docs/fy12osti/51946.pdf U.S. Renewable Energy Technical Potentials] pg. 12
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.[http://www.newenergychoices.org/uploads/FreeingTheGrid2011.pdf Best Practices in Net Metering]
A 2012 estimate suggests that a typical 5 kW system will pay for itself in about 14 years, and thereafter generate a net savings of $16,622 over the 25 year life of the system.[http://solarpowerrocks.com/tennessee/ Tennessee]
Climate impact

Solar power installations in Tennessee have a relatively high climate impact, because almost 25% of the state's electrical generation (as of 2021) comes from coal.{{Cite web|last=Peters|first=Adele|date=2021-08-31|title=This startup helps build solar farms where the grid is dirtiest|url=https://www.fastcompany.com/90670612/this-startup-helps-build-solar-farms-where-the-grid-is-dirtiest|access-date=2021-12-19|website=Fast Company|language=en-US}}
A Nashville-based startup, Clearloop, is targeting solar installations based on three criteria: “Where are the sunniest places? Where’s the grid the dirtiest? And where can a dollar invested in infrastructure go the longest way?”{{Cite web|last=Peters|first=Adele|date=2021-08-31|title=This startup helps build solar farms where the grid is dirtiest|url=https://www.fastcompany.com/90670612/this-startup-helps-build-solar-farms-where-the-grid-is-dirtiest|access-date=2021-12-19|website=Fast Company|language=en-US}} The company's first installation, in Jackson, has capacity to power about 200 homes. Clearloop plans to build additional installations based on investment by companies which want to transition to 100% renewable electricity or offset corporate emissions.{{Cite web|last=Peters|first=Adele|date=2021-08-31|title=This startup helps build solar farms where the grid is dirtiest|url=https://www.fastcompany.com/90670612/this-startup-helps-build-solar-farms-where-the-grid-is-dirtiest|access-date=2021-12-19|website=Fast Company|language=en-US}}
