Solar Panel Installation Cost in Memphis, TN

Memphis is unusual among US cities because it is served by Memphis Light, Gas and Water (MLGW), a municipal utility that purchases wholesale power from the Tennessee Valley Authority (TVA). This TVA connection shapes everything about solar in Memphis.

TVA has its own distributed generation policy that MLGW follows. TVA's Green Connect program allows residential solar installations with net metering style credits, but the rates and terms are set at the TVA level, not by MLGW directly.

The solar resource is good at about 4.8 to 5.2 peak sun hours per day. The federal 30% ITC expired December 2025. Tennessee has no state income tax (on wages) and no state solar incentive. Memphis's very low electricity rates (MLGW/TVA rates are about $0.10 to $0.12 per kWh) are a double edged sword: cheap power keeps your bills low but also makes the solar savings smaller per kWh.

Memphis averages 4.8 to 5.2 peak sun hours per day. A 7 kW system produces about 9,200 to 10,800 kWh per year. Memphis has hot, humid summers and mild winters with light snow (rarely more than 5 inches per year).

Heat and humidity: Summer temperatures reach the mid 90s regularly. Panel efficiency drops slightly but production volume remains high due to long daylight hours.

Memphis incentives:

MLGW / TVA: • TVA's Green Connect program provides the framework for residential solar • Net metering credits at rates set by TVA policy • MLGW rates are approximately $0.10 to $0.12 per kWh, among the lowest in the US • Low rates mean lower solar savings per kWh produced

Tennessee state: • No state income tax on wages means no state solar tax credit is possible • Property tax: Tennessee law exempts solar equipment from property assessment • Sales tax: Tennessee charges state and local sales tax on solar equipment (combined about 9.25% in Shelby County) • No state solar rebate program

Federal: 30% ITC expired December 2025.

The honest truth about Memphis solar: the economics are tighter here than in most cities because MLGW's rates are so low. Solar makes the most sense for Memphis homeowners with higher than average bills ($130+ per month) or those motivated by power independence and environmental goals.

Memphis installation notes:

Permitting: Shelby County or City of Memphis Building Division handles permits. Processing times are variable.

TVA interconnection: Your installer must coordinate with MLGW and TVA for grid interconnection. This can add time to the process. Budget 4 to 8 weeks for the full interconnection process.

Installer market: The Memphis solar market is smaller than Nashville or Atlanta. Look for companies with experience navigating the TVA/MLGW interconnection process specifically.
