Methodology: How We Ranked the Best Solar Companies in St. Louis

EcoWatch's solar experts analyzed each solar company in St. Louis 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 St. Louis


Below are some the criteria we examined specifically for Michigan 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 St. Louis

Even though solar panels can save you money on power bills over time, it’s necessary to take into consideration the upfront costs.The cost of solar and the savings it generates vary depending on some key factors such as:

  • Incentives: The federal solar investment tax credit, which can save you some money, lets you deduct 0 of the cost of installing your solar panel system from your federal taxes. In addition, not including incentives, you can save about $21,000 over 20 years on your energy bills.
  • System size and type: Some models are more expensive than others, so the one you want to get can raise or lower your upfront cost. Plus, the more solar panels you need, the more it'll cost.
  • The amount of sunlight your roof gets: Thanks to St. Louis’s relatively low amount of average daily sunlight, you might not see as many savings on your power bills.
  • How much energy you use: If your family needs to use a lot of energy, you'll benefit more from switching to solar.

So is a solar panel system worth it? Whether you’re trying to reduce your energy bills, greenhouse gas emissions or both, solar panels are a great investment for many St. Louis homeowners.

Which solar power company is the best in St. Louis?

In St. Louis, Michigan Solar Solutions is the most reputable local solar company. Our team of experts rates it 3.00 stars, so it's a great choice if you're planning to add solar panels to your home.

What are the best and worst things about solar power?

The most notable cons are that solar panels don’t work as well when there’s limited direct sunlight, the startup costs are high and solar panels can be an eyesore.

Is it worth installing solar panels on my home?

Solar panels call for a considerable upfront investment that usually costs at least ten thousand dollars, but whether or not solar panels are worth it depends on a collection of factors like the cost of electricity near you and the amount of direct sunlight your roof gets.

What are the different types of solar panels?

Polycrystalline panels are less expensive but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other types can’t, like on curved surfaces or cars, but they are also less efficient.
