The 5 Best Solar Companies in Tennessee To Save You Money

The 5 Best Solar Companies in Tennessee To Save You Money

We’re all looking to save money where we can these days, and one area is in our home energy. Living in an increasingly environmentally-conscious era, many homeowners are looking to solar panels to both save money on their energy bills and do their bit for the environment.

Historically, solar panels haven’t been the most cost-effective option when it comes to powering the home. Increasingly, however, solar panel installation is bringing with it much shorter payback periods as well as flexible payment options, meaning it isn’t the reserve of the rich it perhaps used to be.

As a state, Tennessee gets over 200 days of sunshine per year, so in terms of renewable options, it’s hard to look past the promise of the photovoltaic. So, if you’re in Tennessee, want solar panels installed, and want to save money on your energy bills as quickly as possible, read on!

Tennessee Incentivises Solar Power

The state of Tennessee is pretty progressive when it comes to its incentivization of solar power, not only from a tax perspective but a legislative one, too. Below, we’ve listed some of the ways you can benefit financially from going down the green route of solar energy.

Tax Incentives and Other State-Wide Benefits

One of Tennessee’s main benefits when it comes to solar power is the Green Energy Property Tax Assessment. Established over a decade ago now, in 2010, this property tax exemption relates to geothermal electricity, wind power, hydrogen power, and of course, what we’re interested in, solar photovoltaics.

The state only takes 12.5% of the project costs as taxable property value. In practical terms, this means that by installing solar panels your annual property tax bill will go up only slightly. Given that the initial financial outlay for solar paneling can already be sizeable, it’s reassuring for buyers to know that their property tax isn’t going to soar thanks to the sun.

The Dispersed Power Production Program set up by the Tennessee Valley Authority (TVA) is another thing to consider when thinking about installing PV panels on your property. This program enables both residential and commercial property owners to sell excess generated electricity back to the TVA. This offers an easy, additional (and importantly passive) stream of income.

Laws Involving Solar Power

Tennessee has laws in place to ensure that properties with solar paneling aren’t overshadowed in any way. These are known as solar easement laws and they offer handy legislative support to ensure you don’t get into any property disputes with your neighbors over your solar paneling being “left in the dark” in any way.

How Much Does it Cost to Go Solar in Tennessee?

Although this is a bit of a, “How long is a piece of string?” question there are some general factors that affect how much it will cost you to go solar in Tennessee. These include property size, parts, and labor costs, and whether you make use of a payment plan (and if so, the particular details of said plan).

On average, a Tennessee resident can expect to pay between $20,000 and $30,000 mark for solar installation (with no exemptions added). This reduces to $10,000 to $20,000 once you apply the 30% federal solar tax credit. Find out how Tennessee compares to Massachusetts and Iowa when it comes to its approach to solar.

Types of Solar Power

Before you get smart and tell us there’s only one type of solar power, and that it comes from the sun, that’s not what we mean. We’re talking about whether your solar power is grid-tied, off-grid, or a hybrid of the two.

Grid-Tied Solar Power

Having a PV system hooked up to the mains grid brings with it several benefits; mainly, the convenience and ease of maintenance. It also means you can significantly lessen your bills by returning excess electricity to the grid.

The disadvantage of this setup is that your power goes out during grid outages. Also, if you live in a particularly remote area then the cost of extending power lines can make an off-grid setup more attractive.

Off-Grid Solar Power

An off-grid solar power system involves photovoltaic panels generating electricity. A solar battery then stores this and your property draws its power from it. This means you’re not at all reliant on the mains grid, however, you are reliant on the panels themselves. You need a heavier-duty/more powerful solar panel system if you’re not going to have a grid to rely on.


Increasingly popular is the hybrid setup. This features both a grid connection as well as a solar battery to store excess power. This means you don’t waste excess electricity and that you have access to power in the event of a power outage. What’s more, you still have the convenience of a grid connection as and when you need it.

To Buy or to Lease

Another question regarding investing in solar panels in Tennessee is whether you buy your solar panels or lease a system.

The benefits of buying your solar panels outright are much the same as the advantage of purchasing anything in one lump sum, rather than entering a finance agreement; namely, you pay a larger sum upfront, however, you don’t have to pay subsequent payments (which have interest on).

Conversely, solar panels aren’t cheap, and so a loan or lease agreement is therefore a more viable option for many homeowners. With the flexible payment options offered by many solar panel installers (like the ones mentioned above), the leasing route can be preferable if you’re looking to spread the financial hit.

Final Thoughts

So, there you have it – the five best solar companies in Tennessee. All of which can save you money on your energy bills with their systems. As with any investment, before committing, make sure you shop around and see which of the companies best suits you.
