Methodology: How We Ranked the Best Solar Companies in Sullivan

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


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 Sullivan

We get that for many homeowners, the choice to invest in solar highly depends on installation costs.Some significant things that determine the cost and possible savings include:

  • Choice of solar panels: The type of solar panels you want will affect your total cost. High-efficiency monocrystalline panels are more expensive upfront but can also lead to more savings over the lifetime of your system. If you don’t need to maximize efficiency, you can opt for a higher number of more affordable panels.
  • 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 make as much energy, which will leave you with lower savings on energy bills than someone with a roof that gets lots of sunlight.
  • How much energy your home consumes: Households that need lots of power each month may require more solar panels and, consequently, be more expensive, but will also enjoy more savings over time.
  • How much you spend on energy: If your local utility rates are quite high, there's a better chance you'll get a higher return on your investment in solar panels. In Sullivan, you can save an average of $1,291 a month on your electricity bills.

There are lots of wonderful benefits of solar despite the upfront cost of installation. It can help the environment and your finances. Additionally, it can boost the value of your home, leading to even more benefits if you want to sell your home later.

Environmental Impact of Switching to Solar in Sullivan

EcoWatch's Sullivan, MO Solar Company Rankings FAQs

What is the most reputable solar panel installer in Sullivan?

In Sullivan, Streib Company is the best local solar company. Our team of experts rates it 4.90 stars, so it's a solid choice if you're planning on installing solar panels on your roof.

Are solar panels actually eco-friendly?

Producing solar panels needs to use chemicals and produces toxic waste that can be bad for the environment, which is the main drawback of solar panels.

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

The average payback period for solar panel installation is about 14.2 years, but the exact period depends on local electricity costs, incentives and net metering programs.

How often do solar panels have to be replaced?

Though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they should be disposed of. What this means is how much energy they produce will have decreased by about 0.8% each year since installing them. You can replace them after having them for that long or you can continue to use 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.
