Methodology: How We Ranked the Best Solar Companies in Bay St. Louis

EcoWatch's solar experts analyzed each solar company in Bay 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 Bay St. Louis


Below are some the criteria we examined specifically for Mississippi 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 Bay St. Louis

The cost of putting up a solar panel system has gone down greatly in the past several years, but it’s still a substantial investment for most homeowners.Some important things that affect the cost and possible savings include:

  • How much energy you use: If your home regularly uses a lot of energy, you'll benefit more from installing solar panels.
  • The model of solar panels you want: More efficient models have higher prices, so that will affect your budget for your solar project.
  • 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 $21,000 over the first 20 years with your system, too.
  • Average daily sunlight: Since Bay St. Louis gets lots of sunlight, your solar panel system will most likely be able to produce enough energy to power your whole home, which influences how much your solar panels can save you on your electricity bills.

As a result of solar panels decreasing in cost as well as several solar incentives, they are a sound investment for many homeowners.

EcoWatch's Bay St. Louis, MS Solar Company Rankings FAQs

What is the most reputable solar panel company in Bay St. Louis?

The best local solar company in Bay St. Louis is SolaTrue of New Orleans, LA, with a rating of 3.00 stars.

What are a few of the biggest pros and cons of going solar?

A few of the biggest pros are that it lowers your power bills, it’s environmentally friendly, and it gives you a good return on your investment (ROI). The most notable cons are that solar panels don’t produce electricity at night, the installation cost is pricey and solar panels aren’t always aesthetically pleasing.

Is it worth putting solar panels on my home?

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.

How often do solar panels need 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 the amount of energy they produce will have decreased significantly after that point. You can opt to replace them once you've had them for that long or you can keep using them at a lower efficiency after that time.
