As you browse our top choices, you may notice that popular companies like Vivint Solar don’t appear in our reviews. The exclusion is intentional due to notoriety for various issues, including lawsuits and other headaches that can tie up your solar installation process.
Note: The EcoWatch Ratings you see in the company snapshots at the top of this page reflect our overall assessment of the company, but our rankings reflect the best solar companies in Tennessee, specifically. If you notice that a company lower on our list has a higher EcoWatch Rating, it’s likely because it’s a great company but there are better installers for this specific area.

EcoWatch Criteria For Selecting The Top Solar Company In Tennessee
Our solar team at EcoWatch knows what it takes to be a great solar installation company. We use a tried and true process of vetting every solar company we come across. The major aspects we consider include:
Warranty
Fantastic solar companies usually offer equally as fantastic warranties. Generally, the companies that firmly believe in their products and are confident in their workmanship offer the best warranties.
On the other hand, companies that aren’t as sure of their products or workmanship likely won’t offer the best protection on your brand new investment.
Year Founded
For the most part, older, well-established solar companies tend to offer their customers a wealth of experience and knowledge and a finely-honed skillset. They tend to have better workmanship and quality (on average) compared to new companies.
However, some newer companies can offer excellent services as well. Regardless, this is an aspect we take note of.
Services Offered
Some solar companies offer various services, including roofing, electrical services, solar water heaters or battery backups, while others simply specialize in solar panel installation. Additional services that apply to solar installation can be beneficial.
For example, if your roof couldn’t support the solar energy system, you may need to outsource and have another contractor come in to upgrade the roof. However, if the solar company offers roofing services, it may be able to handle it for you.
Solar Panels Offered
Excellent solar companies usually offer a range of solar panel brands and sizes to accommodate the needs of various projects, no matter how big, small, or unique. Plus, this gives you the option to choose lower-cost solar panels or ones with better efficiencies.
Solar Pricing and Financing
The best solar companies offer competitive pricing that easily combines the best features, all in one valuable package. A new clean energy system isn’t feasible without financing for many homeowners. So, we look for companies that offer several financing options that will accommodate the needs of various budgets.
With great financing, some homeowners can make payments that are less than their previous electric bills.
Industry Affiliations
Many solar companies have various affiliations throughout the industry. This is something we note during our selection process, as it can be informative.
Size of Company
The company’s size may be a defining factor for some homeowners. Larger companies may offer better rates or faster service, which can make them a more appealing choice.
However, this isn’t to discredit smaller companies, as they may offer equally fast service or competitive rates.
