Today's Homeowner looks at dozens of datapoints on solar companies to come up with our data-driven rankings. It's not possible for a company to pay for preferential treatment in our rankings. We look at the following key factors in determining who should top our list:
Installing solar panels can cut your electricity costs and help the environment by reducing your carbon footprint. When evaluating if a solar provider is a good fit for you, consider these key factors.
Confirm that your solar installer is properly licensed. This help guarantee that the work is done properly using the most up-to-date installation methods. 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 project demands. Even if a project doesn't cross the $25,000 value threshold, you will still need a master electrician or electrical journeyman to handle permit work.
Check review sites like TrustPilot, Google Reviews, and the Better Business Bureau (BBB) to see customer feedback about local solar companies. Detailed reviews can help you assess a company's reliability and customer service. Use caution with companies that have no reviews or mostly negative ones.
To find a solar company that fits your budget, ask for free, detailed quotes from 3–5 providers. The quotes should outline all costs and list the solar equipment included. Looking at several quotes helps you identify the option that best fits your budget.
High-quality solar installations should come with robust workmanship and performance guarantees. The workmanship guarantee covers any installation issues like poor alignment, poor wiring, or cracks in the panels. The output warranty ensures an energy generation baseline. Strong warranties reflect a solar provider's confidence in its installations.
Solar energy can help decrease your electricity costs over time. When evaluating solar panel's cost and value, be sure to weigh these considerations.
The average Knoxville homeowner will spend around $19,730 on a home solar system after federal tax refunds. Solar arrays in Knoxville cost approximately $3,580 per kilowatt, with the average residential solar system being 7.9 kilowatts. An estimate from a local solar provider will include costs for preliminary work, labor, and permit fees, and will account for your system's capacity, size, and panel type. Some homeowners prefer to lease their solar panels in order to reduce upfront costs.

Generally speaking, a solar photovoltaic (PV) array can be used to power any household system or appliance that uses electricity. In the smallest case, you can use a solar water heating system.
There are many advantages of home solar energy. You can reduce emissions, save money, and raise your property values. With the right storage equipment, solar panels can also provide you with further energy independence and offer some protection from power outages.
Yes. The grid in Knoxville already uses a large share of renewable energy sources, and you may be able to sell your excess generated energy to your utility for additional cost savings.
You might be pleasantly surprised at how quickly you can get a return on investment from your solar panels. The sun shines frequently in Knoxville, meaning your payback period could last 36.0 years per 5 kW of capacity on the high end.
While solar energy might not be ideal for some in wet or dark areas, the latest generation of equipment and energy storage systems could boost your property's solar viability enough to achieve a return on investment. A contractor could also recommend a different primary source of renewable energy like wind or geothermal to boost your generation.
The most common types of home solar panels in Knoxville include thin-film, monocrystalline and polycrystalline. Monocrystalline panels are balanced and efficient, while thin-film and polycrystalline panels pair good performance with greater upfront value. Ask your local provider about what kinds of solar panels they work with.
