After the federal solar investment tax credit, the average solar energy system is $20,916 in Tennessee, which is more expensive than in many other states. The national average is $16,715. Though going solar in Tennessee costs a bit more, you can take advantage of a property tax break to help with some of the cost.

Key insights

  • You can take advantage of solar tax breaks and financing programs.
  • The average federal tax credit value is $8,964 in Tennessee.
  • Tennessee residents with solar panels save an estimated $19,688 over 25 years.

Solar incentives in Tennessee

The federal solar investment tax credit (ITC) is the biggest factor in reducing the cost of going solar in Tennessee. If you install a residential solar panel system by the end of 2032, you will receive a federal income tax credit equal to 30% of the system's total cost, including equipment, labor and permits.

The federal solar investment tax credit drops to 26% in 2033 and 22% in 2034.

For example, the average system in Tennessee costs $29,880. With this price, you can get a $8,964 credit when you file your taxes.

The solar tax credit is not a rebate or refund — you must claim it when you file federal taxes in the year that your solar panel system becomes operational. To do this, you have to complete Form 5695. The ITC is a nonrefundable credit. If you don’t use the full tax credit, it rolls over into the next tax year.

Statewide residential solar incentives in Tennessee

Tennessee only has one statewide residential solar incentive — the Green Energy Property Tax Assessment. To qualify, your home has to be certified as a green energy provider. It’s also available for commercial and industrial projects. Incentive amounts depend upon the sector.

What to know about net metering in Tennessee

If your solar system generates more energy than you need (and you don’t store the extra in a solar battery), you have the option to sell the surplus to your local electric company through a process known as net metering.

Tennessee doesn't have any net metering policies in place. This means there are no state laws mandating electric companies to offer net metering. Some local electric companies might still offer net metering programs, however. For example, Appalachian Power runs its own net metering program.

How can I pay for solar panels?

You can pay cash, but most people finance solar panels. A solar loan works like any other type of loan — there’s an application and approval process, and you pay it back over time (with interest). If you are considering a solar loan, lease or PPA (power purchase agreement), always ask:

  • Is there a down payment?
  • How much will I pay per month?
  • When will monthly payments increase, and by how much?
