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

Solar panels are powered by a free energy source — the sun — but to take advantage of this you first need to pay to install your panels.Some significant things that affect the cost and possible savings include:

  • Your income and budget: This determines what type of solar panels you can purchase.
  • Your power bills: This will determine how much money you might save. In Louisville, the average resident can save about $970 a year on their electricity bills.
  • Incentives: Something that can save you money on your solar project is the solar investment tax credit (ITC), which is a tax credit that lets you deduct from your taxes a percentage of the project cost. You can also save a decent amount of money on your power bills, which can generate an average of $19,000 of savings over 20 years.
  • Energy consumption: Installing a solar system may be too pricey an investment for households that don’t consume a lot of energy a month.

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

EcoWatch's Louisville, CO Solar Company Rankings FAQs

What is the most reputable solar installation company in Louisville?

The top local solar company in Louisville is Smart Wave Solar, with a rating of 4.80 stars.

Are solar panels actually environmentally friendly?

Solar panels can be harmful for the environment when manufacturers use toxic chemicals in the manufacturing process. Chemicals can make solar panels difficult to recycle safely once they’ve reached the end of their lifespan. Solar panel manufacturing 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 14.1 years, but your solar payback period will vary depending on your utility costs. The higher your typical electricity bill, the faster your solar panel system will recoup your installation costs.

What is solar panel capacity and how much do I need for my house?

Solar panel capacity is rated depending on the amount of power they produce under standard testing conditions. Since each panel can typically produce about 250 to 400 watts per hour, the average household will need 20 to 35 panels.

Our goal is to reach as many people as we can with sensible solutions like solar energy.
