Tennessee Solar Guide: TVA Territory Solar Options

Tennessee's solar landscape is shaped by TVA (Tennessee Valley Authority) and local power companies. Understanding how TVA's programs work is key to going solar in the Volunteer State.

Quick Answer
Tennessee solar depends heavily on your local utility since TVA provides wholesale power but local utilities set solar policies. An 8 kW system costs $19,200-$24,000. Production is good at 4.6 peak sun hours. Nashville Electric, KUB, and MLGW each have different programs—always check with your specific utility about net metering and TVA Green Connect availability.

Tennessee Solar Overview

💡
From my experience:

Tennessee is tricky because of TVA. Your local utility sets their own solar policies, even though they all buy power from the Tennessee Valley Authority. Nashville Electric, KUB in Knoxville, and MLGW in Memphis all do things differently. You really need to call your specific utility before assuming anything about solar in Tennessee.

Tennessee is unique—most of the state is served by local power companies that buy power from TVA (Tennessee Valley Authority). Solar policies vary by local utility, but TVA's Green Connect program provides a consistent option.

[Editor's Note, Jan 2026]:Tennessee solar policies vary significantly by local utility. TVA Green Connect and local utility programs change periodically. Contact your specific local power company for current net metering and solar program details.
