Tennessee Solar Panel Savings Overview

Tennessee receives an average of 4.5 peak sun hours per day, providing a solid foundation for residential solar energy. With electricity rates averaging 12.1¢ per kWh — below the national average — longer payback periods are typical but savings still add up over time. The typical Tennessee homeowner with a 6kW system can expect to save approximately $1,020 per year.

Solar Energy Production in Tennessee

A standard 6kW residential solar panel system in Tennessee produces approximately 7,884 kWh per year. This accounts for a system efficiency factor of 80%, which includes panel degradation, inverter losses, and temperature effects. At 4.5 peak sun hours per day, Tennessee offers good solar production — enough to offset a significant portion of typical household electricity consumption.

Tennessee Electricity Rates and Solar Context

The average residential electricity rate in Tennessee is 12.1¢ per kWh according to EIA data. While this rate is below the national average, electricity costs are rising approximately 2-3% per year. Over a 25-year system lifetime, your cumulative savings will still be substantial. With utility rates increasing annually, your solar savings grow each year.

Tennessee Solar Incentive Programs

TVA Green Power Providers program. No state tax credit. Federal 30% ITC. All Tennessee residents are eligible for the federal 30% Investment Tax Credit (ITC), which reduces the cost of a solar system by 30% of the total installed price. Tennessee does not currently have a statewide net metering mandate, which can affect the financial returns of solar installations. Some utilities offer voluntary solar buyback programs.

Net Metering in Tennessee

Tennessee currently lacks a comprehensive net metering policy. This means that excess solar energy exported to the grid may not be compensated at the full retail rate. However, many Tennessee homeowners still find solar financially attractive by sizing their systems to match their consumption patterns.

Best Cities for Solar in Tennessee

The best cities for solar panels in Tennessee include Nashville, Memphis, Knoxville, Chattanooga, Clarksville. Solar production can vary by location within the state due to differences in cloud cover, local shading, and microclimates. Southern-facing roofs with minimal shading produce the most energy. Homeowners in Nashville and Memphis can typically expect production close to the state average of 4.5 peak sun hours per day.
