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 Colorado 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

The cost of installing solar panels has dropped immensely in the past few years, but it's still a large investment for most homeowners. Some significant things that influence the cost and possible savings include:

  • How much you spend on energy: The typical household in Louisville shells out around $1,000 a year on home energy use alone, so you could end up with that much in savings.
  • The amount of sunlight your roof gets: Due to Louisville's very high amount of average daily sunlight, you should be able to save a lot on your electric bills.
  • Incentives: Something that can make your solar project cost less is the solar investment tax credit (ITC), which is a tax credit that's equal to a percentage of the project cost. You can also save on your power bills, which can result in an average of $19,000 of savings over 20 years.
  • Your income and budget: This guides what type of solar panels you can buy.

So is buying solar panels worth it? Whether you're trying to reduce your electricity costs, carbon emissions or both, solar panels are a good investment for many Louisville homeowners.

Solar Incentives in Louisville

One of the benefits of installing a solar panel system is receiving federal and potentially state incentives. In addition to the federal tax credit incentive, there are also some state- and city-level incentives, which in most cases, stack with the federal incentive, so you get to save even more. In our article on solar incentives, you can read about the incentives you qualify for near you.

Environmental Impact of Switching to Solar in Louisville

One of the most compelling reasons to embrace solar energy is to cut your reliance on nonrenewable energy sources like burning fossil fuels, which are harmful for the environment. But how much can switching to solar actually help the environment? The average person has a substantial carbon footprint. Between their car, which is responsible for over 10,000 pounds of carbon dioxide emissions every year, and energy for their home, it can be overwhelming to figure out what to do. Switching to solar is one of the easiest things you can do to help. In fact, if you install solar panels, you could reduce your carbon dioxide emissions by about 100 pounds each year. If you care about the environment, you'll likely get that there are many advantages to adopting solar energy other than just saving money on electricity. You can also help preserve the environment, which some would argue is priceless.

EcoWatch's Louisville, CO Solar Company Rankings FAQs

Which solar company is the best near me?

The top local solar company in Louisville is Freedom Solar Power, with a rating of 4.13 stars.

Are solar panels actually eco-friendly?

Solar panels can be bad 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.

Are solar panels worth it?

Solar panels can be a great investment for most homeowners, but admittedly, they might not be worth it for everyone. If your home doesn't get enough sunlight or your electricity bills are already pretty low, solar panels might not be for you.

When is the best time of year to install solar panels?

You can put up solar panels whenever it's convenient for you, but consider doing it in the winter when there's less demand. With fewer homeowners switching to solar, you could potentially see faster installation times and more savings.

Our goal is to reach as many people as we can with sensible solutions like solar energy. Our team of full-time local researchers collects solar price and installation data for every city in America then compiles it to create these digestible city guides.
