With so many solar companies to choose from, we know how daunting it can be to find an installer you can trust with your home’s solar system. To help you make the right decision, we’ve put together this comprehensive guide to the best solar companies in Tennessee, as rated by our SolarReviews experts and Tennessee residents who’ve already gone solar.

We look for solar companies with owners who understand that when they sell you a solar system, you expect them to be there for the next 25 years to fix any issues that may arise. Here are the top companies we recommend for solar in Tennessee:

Best solar companies for home battery installations in Tennessee

Batteries have become increasingly popular because they take an intermittent energy source like solar and turn it into a reliable and consistent supply of electricity. We recommend getting a solar battery quote if you want a backup power source or if your utility company doesn’t have a net metering program that buys excess solar energy at the full price of power, as you could save a little extra on your electric bill. 

Tennessee doesn’t have a statewide net metering program, but the Tennessee Valley Authority (TVA) does purchase excess solar energy at a very low rate. Because of this, installing energy storage can provide Tennessee solar homeowners with some extra electricity bill savings.

Tennessee doesn’t currently offer any upfront rebates for purchasing a solar battery. But, if you want peace of mind that your home will have backup power in the event of a power outage and to see extra savings on your electric bills each month, a solar battery can be worth it.

Here are some Tennessee companies that install panels and solar battery storage systems:

How to find the best solar panel company near you

Picking a solar company is the most important decision you make when going solar. You need to trust them to drill holes in your roof, help you navigate financing and incentives and provide you with 25+ years of customer service.

Tennessee incentives and rebates

Solar incentives and rebates can cut the cost of installing solar in Tennessee by thousands of dollars. The most significant incentive is the 30% federal solar tax credit, available to any taxpayer in the country when they purchase solar panels or battery storage. 

Some states and utility companies offer additional solar incentives, saving homeowners even more money. Here are the solar incentives available in Tennessee:

What to look for in solar quotes in Tennessee

Once you’ve found a few companies you like, you can start getting solar quotes. You can get a better deal when you get quotes from multiple solar installers; we suggest getting at least three quotes. Here are a few of my favorite tips and tricks for comparing quotes and what questions you should ask installers.

System size and energy production

All solar quotes should include the size of the system and how much energy it is projected to produce. Most of the quotes you get will probably be in the same ballpark. But, if one is drastically larger or smaller than the others — ask about it! Maybe one installer included shading from a tree, while another based its estimates on having that tree removed.

Tennessee’s climate is fairly seasonal, so you can expect more solar production in the sunnier summer months. Tennessee gets around 4.5 to 5 peak sun hours every day, which is pretty average in the U.S. You might need more solar panels to offset your energy usage in Tennessee than in a sunnier state like Arizona. Still, your quote will probably be for an average-sized system.

If you choose reliable installers, you can trust that these estimates will be as accurate as possible. But you can always double-check using the SolarReviews solar calculator and enter the information received in your quotes. 

Pricing

You should know as much as possible about how much the solar panels cost. Make sure you know both the total cost of the system and the price per watt of solar installed. The cost per watt makes it easier to compare prices between quotes and gives you a better idea of how fairly the system is priced. The average price of solar is about $2 to $4 per watt (without a battery) in Tennessee, so anything in that range is a fair price.

Financing

Financing is one of the most important things to look for in your solar quote. There are a few different things to keep an eye out for, depending on what type of solar financing you’re using. 

If you’re looking to use a solar loan, you should ask the company for both a cash quote and the financed quote. Solar loans include something called dealer fees, which can sometimes add 20% or more to the total cost of your system in exchange for a lower interest rate. It’s worth comparing what dealer fees and interest rates you’re quoted from different companies to get the best deal possible. 

If you want a solar lease or power purchase agreement (PPA), you’ll want to look for an escalator clause in the contract. The escalator clause outlines how much your payments will go up every year. Ideally, this should be lower than the rate at which electric prices increase in your area, typically about 3% annually. If the escalator rate is higher than this, you could end up paying more than if you hadn’t gone solar at all!

Payback period

Some quotes may include when you’ll break even, meaning when your panels have saved as much as you spent on them. If it’s not explicitly listed on the quote, you can compare any savings estimates they provide to the system’s total price and get a rough estimate of when your panels will pay themselves off. The shorter the payback period, the better.

Equipment

Good quality solar installers will carry good quality equipment. So if you pick an installer you trust, you can expect reliable products. But, it can’t hurt to research and ask the installer questions about what would be going on your roof. 

Most solar panels installed today are about 400 watts in size and have efficiency ratings above 19%. Higher wattage and efficiency panels can produce slightly more electricity but may add a price premium. You’ll want to make sure the solar panels have the industry standard 25-year product and performance warranties.
