Methodology: How We Ranked the Best Solar Companies in Hattiesburg

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


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 Hattiesburg

For many readers, the decision of which solar installer to go with depends on costs. There are several factors you should take into consideration when trying to figure out the overall cost and how much you can save, such as:

  • Choice of solar panels: The kind of solar panels you get will affect your total cost. High-efficiency monocrystalline panels will cost more upfront but can also save you more money 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 power your household needs: If your family uses a lot of energy, you'll reap more rewards from installing solar panels.
  • Incentives: Along with the federal Solar Investment Tax Credit (ITC), which lets you deduct 30% of your overall installation cost, your local government may offer additional tax exemptions, credits or rebates that will help you save even more. Aside from incentives, you can save an average of $21,000 over 20 years with your solar panels, too.
  • Your location: This influences how much sunlight your roof gets, which helps determine how many panels you need.

Solar is a worthwhile investment for most homeowners. You can produce your own electricity instead of paying for it from the grid and take advantage of solar incentives and rebates, all while helping the Earth.

Solar Incentives in Hattiesburg

In addition to the federal tax credit incentive, there are also some local benefits, which in most cases, stack with the federal incentive, so you can save even more. Check out our article on solar incentives to learn what incentives you can take advantage of.

Environmental Impact of Switching to Solar in Hattiesburg

A lot of people want to do their part for the planet, which in many cases is the primary reason for installing a solar system. But how much can using solar energy instead of traditional energy actually affect the environment? The more energy your house uses, the better off the planet will be from you switching to solar since you won't have to use as much nonrenewable energy. Because solar panels don't release carbon dioxide emissions into the atmosphere when producing electricity, they're a good swap for nonrenewable energy sources. In fact, you could reduce your carbon dioxide emissions by about 90 pounds each year. Since solar power is abundant and makes electricity without releasing carbon emissions, adding solar panels to your home is one easy step you can take to help the environment.
