Methodology: How We Ranked the Best Solar Companies in Warrenton

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


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 Warrenton

We understand that for lots of homeowners, the choice to invest in solar highly depends on installation costs. A few important factors that influence how much it will cost to install a solar panel system on your home and how much it could save you over time are:

  • Incentives: One thing that can reduce the cost of 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 money on your energy bills, which can result in an average of $15,000 of savings over 20 years.
  • Your energy consumption: If your family uses a lot of energy, you'll benefit more from going solar.
  • Where your home is: This affects the average daily sunlight your roof gets, which helps determine how many panels you need.
  • System size and type: Some models are more expensive than others, so the one you choose can raise or lower your upfront cost. Plus, the more solar panels you need to buy, the more it'll cost.

There are many good benefits of solar despite the upfront cost of installation. It can help the environment and your wallet. In addition, it can raise the value of your home, resulting in even more benefits if you decide to sell your home later.

How efficient is a solar panel system?
