Methodology: How We Ranked the Best Solar Companies in Wentzville

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


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 Wentzville

The cost of putting up a solar panel system has dropped significantly in the past several years, but it's still a substantial investment for most homeowners. The installation cost is just one important factor you should keep in mind when looking into installing solar panels. How much it'll cost and how much you can save depend on things such as:

  • 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 $15,000 of savings over 20 years.
  • Your home's power bills: With fairly high monthly electricity bills in Wentzville, you could save about $1,200 a year with solar.
  • Your income and budget: This shapes what model of solar panels you can get.
  • How much sunlight your roof gets: If your rooftop doesn't see much direct sunlight, your solar panels won't be able to generate as much energy, which will leave you with lower savings on energy bills than a roof that gets lots of sunlight.

As a result of solar panels decreasing in cost as well as several solar incentives, they are a solid investment for most homeowners.

Solar Incentives in Wentzville

Although solar power is typically a big investment, it can save you a considerable amount of money over time due to reduced energy bills and government incentives. State and city solar incentive programs depend on the location and, sometimes, utility company. A lot of states offer rebates for solar power systems, in addition to the federal solar tax credit. For comprehensive information about local incentives, visit our article on solar incentives.

Environmental Impact of Switching to Solar in Wentzville

If you want to add solar panels to your home, one of the main reasons why may be to reduce your greenhouse gas emissions. You may be curious — how much does making the switch do for the environment anyway? The more energy your family uses, the better off the planet will be if you switch to solar as you won't have to burn as many fossil fuels. Since solar panels don't release greenhouse gas emissions into the atmosphere when generating electricity, they're a good swap for traditional energy sources. In fact, you could expect to reduce your carbon dioxide emissions by about 100 pounds each year. If you want to do your part for the environment, you'll likely understand that there are many benefits of adopting solar power other than just saving money on bills. You can also help protect the environment, which some would argue is invaluable.
