Methodology: How We Ranked the Best Solar Companies in Louisville

EcoWatch's solar experts analyzed each solar company in Louisville based on criteria such as its reputation in the industry, customer reviews, services, warranty coverage and financing. Using this solar methodology, we used the data we collected to rate and rank each company and narrow down our picks for the best solar companies in Louisville


Below are some the criteria we examined specifically for Kentucky solar companies

  • Brand reputation and certifications (20%): We take each company's Better Business Bureau (BBB) score into consideration, as well as how long the installer has been in business (at least 5 years is required, 10 preferred) and what type of solar certifications it holds.
  • Customer reviews (20%): Trust is a top priority at EcoWatch, so we take customer experience under close consideration. We scour different review sites and customer testimonials when ranking our top solar companies, checking sites such as Trustpilot and Google Reviews. We also consider any potential complaints or lawsuits filed against these companies and award or remove points accordingly.
  • Warranty (20%): A company earns a perfect score in this category if it offers 25-year warranties that cover performance, product and workmanship. The industry standard that we measure companies against is 25-year product and performance warranties, along with a 10-year workmanship warranty. We also look closely into the track record of the post-installation support each company provides in terms of honoring its contracts
  • Solar services (10%): All of the companies we review install solar panels, but we award companies higher points if they offer additional services for customers, like battery installation, energy-efficiency audits, and EV chargers.
  • Pricing and financing (10%): It's hard to get exact quotes for solar projects, but we use marketplace research to determine how each company prices its equipment and installation services. Additionally, companies that offer more help for panel financing — like in-house loans, leases, or PPAs — score higher than those that don't.
  • Availability (10%): The bigger the service area, the higher the company will score.
  • Transparency and accessibility (5%): Solar installers that offer free consultations and easy contact methods score higher in this category.
  • Environmental, social and corporate governance factors (5%): A company earns a perfect score in this category if it offers public data disclosure, addresses end-of-life (EOL) products or processes, and demonstrates a commitment to uplifting the communities that it serves.

The Cost and Benefits of Solar in Louisville

We get that for most homeowners, the decision to invest in solar hinges on installation costs.There are several factors you should take into consideration when determining how much it will cost and how much you can save, such as:

  • Incentives: Along with the federal Solar Investment Tax Credit (ITC), which lets you deduct 0 of your total installation cost, your local government may offer additional tax exemptions, credits or rebates that will help you save even more. Aside from incentives, you can save an average of $17,000 over 20 years with your solar system, too.
  • The amount of sunlight your roof gets: If your roof doesn’t see much direct sunlight, your solar panel system won’t be able to produce as much energy, which will give you lower savings on power bills than a roof that gets a lot of sunlight.
  • The type of solar panels you’re thinking of getting: More high-tech panels cost more, so that will affect your budget for your solar project.
  • How much energy costs for you: The typical household in Louisville pays around $1,500 a year on electricity alone, so you could gain that much in savings.

There are lots of good benefits of solar even with the initial cost of installation. It can help the planet and your finances. Plus, it can raise the value of your home, resulting in even more benefits if you want to sell your home later.

EcoWatch's Louisville, KY Solar Company Rankings FAQs

Which solar power company is the best near me?

The best local solar company in Louisville is Solar Energy Solutions, with a rating of 3.00 stars.

What is the negative environmental impact of solar panels?

Solar panels can be harmful for the environment when manufacturers use toxic chemicals when they’re made. Chemicals can make solar panels difficult to dispose of safely once they’ve reached the end of their lifespan. Making solar panels needs a lot of energy as well. The energy payback period is about 1 to 4 years.

How long does it take for solar to pay for itself?

Solar panels usually pay for themselves in about 14.8 years, but your solar payback period will vary based on your utility costs. The more your typical energy bill, the faster your solar panel system will pay for itself.

How long do solar panels last?

Though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they stop working completely. What this means is the amount of energy they produce will have decreased by about 0.8% each year since installing them. You can decide to replace them once you've had them for that long or you can keep using them at a lower efficiency after that time.
