Methodology: How We Ranked the Best Solar Companies in Cottleville

EcoWatch's solar experts analyzed each solar company in Cottleville 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 Cottleville


Below are some the criteria we examined specifically for Missouri 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 Cottleville

When picking a solar company, most homeowners or business owners wonder about the costs above all.Some key things that determine how much it will cost and how much you could save include:

  • Your income and budget: This affects what kind of solar panels you can purchase.
  • Energy consumption: Installing solar panels may be an expensive option for families that don’t use a lot of energy a month.
  • Incentives: The federal solar investment tax credit, which everyone in the U.S. is eligible for, lets you deduct 0 of the cost of your solar system installation from your federal taxes. In addition, not including incentives, you can save about $15,000 over 20 years on your energy bills.
  • How much sunlight your roof gets: If your roof doesn’t get a lot of direct sunlight, your solar system won’t be able to produce as much energy, which will leave you with lower savings on electricity bills than a house with a roof that gets a lot of sunlight.

There are many wonderful benefits of solar in spite of the upfront cost of installation. It can help the Earth and your finances. In addition, it can increase the value of your home, leading to even more benefits if you choose to sell your home later.

EcoWatch's Cottleville, MO Solar Company Rankings FAQs

Which solar installation company is the best near me?

The top local solar company in Cottleville is SunSent Solar, with a rating of 4.90 stars.

What are the best and worst things about solar power?

The biggest advantages of solar power are that it can lower or, in some cases, totally erase your electricity bills, improve the value of your home and cut back on your carbon footprint. The greatest disadvantages are that solar panels can be expensive to install, you may not save a lot if you don’t use a lot of electricity and whether you can install solar panels depends on your roof configuration.

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

The average payback period for solar panel installation is about 14.6 years, but the exact period is influenced by local electricity costs, incentives and net metering programs.

How long do solar panels last?

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

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