Methodology: How We Ranked the Best Solar Companies in Kirkwood

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


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 Kirkwood

Even though solar panels can help save you a decent chunk of change on utility bills over time, it’s important to know the startup costs.The cost and possible savings vary depending on a few key factors such as:

  • Incentives: The federal solar investment tax credit currently allows you to lower your taxes by 0 of the project cost. Your state and city may also have various incentives that you can take advantage of. Plus, you can save about $16,000 over 20 years on your utility bills, not including incentives.
  • System size and type: Some models are more pricy than others, so the one you decide on can raise or lower your upfront cost. Plus, the more solar panels you need, the more it'll cost.
  • How much energy your home consumes: Households that need a lot of electricity each month may require more solar panels and, as a result, be more costly, but will also save more on their energy bills over time.
  • Average daily sunlight: Since Kirkwood gets a decent amount of average daily sunlight, your solar panels can generally produce enough energy to power your whole home, which impacts how much your solar panels can save you on your electricity bills.

So are solar panels worth it? Whether you’re trying to lower your energy bills, carbon emissions or both, solar panels are a great investment for many Kirkwood homeowners.

In our article on solar incentives, you can find out about the incentives you qualify for in your area.

Environmental Impact of Switching to Solar in Kirkwood

Replacing nonrenewable energy with solar power is a great way to do your part for a more environmentally-friendly future.But how much can using solar energy instead of traditional energy actually help the environment? The amount of energy you use is a significant factor to think about.

As you can see, investing in solar has so many other rewards beyond saving money. One of the primary ones is that you can help save the environment too.
