Methodology: How We Ranked the Best Solar Companies in Frontenac

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


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 Frontenac

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

  • The make and model of solar panels you want: More high-tech panels are more costly, so that will shape your budget for your solar project.
  • Energy consumption: Installing a solar system may be too pricey an option for households that don’t consume a lot of energy a month.
  • Incentives: Along with the federal Solar Investment Tax Credit (ITC), which lets you receive a tax credit curretnly worth 0 of your total installation cost, your local government may offer additional tax exemptions, credits or rebates that can help you save even more. Excluding incentives, you can save an average of $16,000 over the first 20 years with your solar panels, too.
  • Your location: This influences how much sunlight your roof receives, which helps determine how many panels you need.

There are several great benefits of solar even with the initial cost of installation. It can help the environment and your bank account. In addition, it can increase the value of your home, resulting in even more benefits if you choose to sell your home later.

Which solar installation company is the best near me?

The highest-rated local solar company in Frontenac is Astrawatt Solar, with a rating of 5.00 stars.

What are the best and worst things about solar power?

A few of the biggest pros are that it lowers your electricity bills, it’s environmentally friendly, and it provides a significant return on your investment (ROI). The most notable cons are that solar panels don’t produce electricity at night, they cost a lot upfront and solar panels can look clunky on your roof.

Is it worth installing solar panels on my roof?

Solar panels can be a fruitful investment for many homeowners, but frankly, they might not be worth it for everyone. If your home doesn't get enough sunlight or your power bills are already fairly low, solar panels might not be for you.

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

Solar panel capacity is rated based on how much power they generate 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.
