Methodology: How We Ranked the Best Solar Companies in St. Louis
EcoWatch's solar experts analyzed each solar company in St. Louis 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 St. Louis
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 St. Louis
When picking a solar company, most homeowners or business owners wonder about the costs above all.There are quite a few factors you should take into consideration when trying to determine costs and your potential savings, including:
- Incentives: Along with the federal Solar Investment Tax Credit (ITC), which gives you a tax credit currently worth 0 of your overall installation cost, your state or local government may offer additional tax exemptions, credits or rebates that can help you save even more. Not including incentives, you can save an average of $17,000 over the first 20 years with your solar system, too.
- How much power your home consumes: Homes that need lots of power each month may call for more solar panels and, as a result, be more expensive, but will also save more on their energy bills over time.
- The amount of sunlight your roof gets: If your rooftop 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 power bills than someone with a roof that gets a lot of sunlight.
- The type of solar panels you can purchase: This depends on what your budget is.
There are several wonderful benefits of solar even with the initial cost of installation. It can help the Earth and your bank account. In addition, it can boost the value of your home, resulting in even more benefits if you choose to sell your home later.

Environmental Impact of Switching to Solar in St. Louis
Going solar can have a meaningful effect on the environment.But you may be wondering – how much exactly can you help by going solar? Adopting solar power is an impactful choice for the environment, due to the fact that the biggest source of greenhouse gas emissions in the country is from burning fossil fuels for electricity, heat, and transportation – all of which can be powered by solar instead.Although making solar panels releases carbon dioxide emissions, the panels make up for it by considerably lowering the amount of CO2 you would have been responsible for if you still used nonrenewable energy. In St. Louis, you can reduce your carbon footprint by 100 pounds a year with solar panels. If you want to do what you can for the environment, you’ll most likely find that there are many advantages to adopting solar power other than just saving money on bills. You can also help preserve the environment, which some would argue is more valuable.

EcoWatch's St. Louis, MO Solar Company Rankings FAQs
Which solar company is the best in St. Louis?
In St. Louis, Astrawatt Solar is the top 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 home.
What are some of the biggest pros and cons of switching to solar?
The greatest advantages of solar power are that it can lower or, for some, 100% erase your electricity bills, improve your home’s value and cut back on your carbon footprint. The biggest disadvantages are that solar panels can be expensive to install, you may not see as many savings if you don’t use a lot of electricity and it doesn’t work for all roof types and locations.
How long does it take to see a return on your investment after buying solar panels?
Solar panels usually pay for themselves in about 13.5 years, but your solar payback period will vary based on your utility costs. The more your typical electricity bill, the faster your solar panel system will recoup your installation costs.
When should I install solar panels?
Despite summer being the most popular time people install solar panels, the perfect time is actually winter. You can save money since there's decreased demand during the winter months, and it allows you to be up and running with solar for the more expensive power bills you may get during the summer.
Our goal is to reach as many people as we can with sensible solutions like solar energy.
