Benefits of Solar Energy

Solar energy has multiple advantages that will enhance your home for years to come.

  • Lowered energy bills: You can avoid the premium cost of grid-tied power by creating some electricity right where you use it.
  • Reduced carbon footprint: Using clean solar power lowers your dependence on fossil fuels, which release greenhouse gases that damage the environment.
  • Better energy independence: Solar systems with battery storage operate through blackouts and emergencies, and you won't have to rely on the electrical grid for your safety and well-being.

How To Choose the Best Solar Company in Nashville

Choosing a company is the first step toward a well-oiled and cost-efficient solar array. Make your choice based on the following essential elements.

Licensing and Training

Tennessee requires any solar energy project valued at $25,000 or higher to be overseen by a licensed "prime contractor." The prime contractor is responsible for hiring licensed subcontractors as the job requires. Even if a project doesn't cross the $25,000 value threshold, you'll need a master electrician or electrical journeyman to pull permits. You should also visit a company's website to learn about its private certifications. Two of the most prestigious are the Solar Heating Installer and PV Installation Professional certificates, backed by the North American Board of Certified Energy Practitioners (NABCEP). Some companies don't publish this information online, so you should also ask your estimator about them.

Cost of Solar Panels in Nashville

The kind of solar panels you purchase dictates how much electricity you can produce. Monocrystalline panels give you the best performance but cost more upfront. Polycrystalline panels produce less power, but they're worth it if you want a traditional panel style without the high cost. Thin-film panels aren't the best for large residential installations, but they are excellent accessories for non-traditional roofs.

Additional components, such as battery storage and electric vehicle (EV) chargers, will add to your overall costs. However, they might make your solar system more efficient and convenient to use. Not every solar company provides these extras, so look for a company that sells them if it's a priority for you.

If you're a resident of Nashville and are looking into a five-kilowatt solar energy system, you could expect to pay about $17,900 for materials and labor. Find more information on specific component and panel costs in the table.

Solar Panel Cost Average Cost
Solar Monocrystalline $1,144
Solar Polycrystalline $892
Thin-Film $521
Solar Battery $732
Solar Home EV Charger $2,745

Financing Solar Energy in Nashville

Choosing the best financing solution will influence your overall solar system cost and expected savings. Common payment options include power purchase agreements, loans, leases, and cash payments. Though it involves a large up-front payment, cash is the most affordable choice because it doesn't accrue interest and qualifies you for incentives. Solar loans are the second most effective option. As with a car or home loan, you'll pay a monthly rate towards system ownership, including interest. You can still apply for valuable solar incentives, and depending on your lender, you could put as little as $0 down. Solar leases allow you to pay a monthly fee to rent your panels, while a PPA lets you pay a fluctuating rate based on only the energy you use. We generally advise against these options since you won't own your system and are disqualified from solar incentives, but they might be appropriate in certain circumstances. Look for installers that offer two or more payment plans to find the right fit for your pocket.

The table below lists the average payback periods for different capacities of solar systems in Nashville.

You are eligible for a 26% federal tax credit for new solar energy devices until the year 2032. Municipal and state governments and utility companies might also offer rebates, discounts, and unique financing solutions that could save you more.

Solar System Capacity Estimated Payback period
1 kW 2.4 years
2 kW 4.8 years
5 kW 12.1 years

Frequently Asked Questions About Solar in Nashville

How much money could I save by going solar in Nashville?

On average, Nashville homeowners spend approximately $1,624 per year for energy. Once you pay off your solar array, you could reduce your costs by $502.03 for every kilowatt you produce.

How common is solar energy in Nashville?

Yes, solar energy is becoming increasingly popular in Nashville. Some homes already benefit from solar power on-site or through utility grids, and they're supported by a state solar economy with 4194 jobs and counting.

Should I expect a property value increase after installing solar panels?

Yes, solar panels will raise your property value. According to the National Renewable Energy Laboratory (NREL), for every dollar you save on energy bills, your home value increases by $20. So, if your panels save you $600 per year on energy costs, your property could appreciate $12,000.

How many years will an average solar system last?

Today's solar installations are incredibly durable, lasting up to 25 years. Monocrystalline panels and other premium models tend to work longer than less expensive models.

Is installing solar panels a quick job?

Your solar job's duration will depend on its complexity and size, as well as Nashville's permit and inspection procedures. It could take a couple of weeks to a few months on average.

How long does it take to pay back a solar loan in Nashville?

The average payback period for a solar loan in Nashville is 25.0 years. By paying off extra principal each month, you can shorten the payback period and own your system faster.

How can I enhance my solar array's performance?

To enhance your solar system's performance, you can use the following strategies:
  • optimize the panels' position with your solar installer
  • regularly clean your solar panels
  • upgrade to a more efficient inverter trim or cut down trees in the way of your panels
  • use energy-efficient appliances

How are traditional solar loans and PPAs different?

A PPA is a contract between you and your provider. They set up, own, and care for the panels, and you purchase the generated electricity from them for 10–25 years. There will usually be options to extend the agreement and buy out early to own your system.

In contrast, solar loans can come from specialty lenders, local banks, the government and installer. You'll need to pass a credit check to qualify for most of them. While the upfront costs are larger, and you'll be responsible for maintenance, you'll also have complete ownership and can apply for many more financial rewards.
