Methodology: How We Ranked the Best Solar Companies in Williamston

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


Below are some the criteria we examined specifically for South Carolina 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 Williamston

For many homeowners, whether or not you should invest in solar panels boils down to the cost.A few important factors that dictate how much it will cost to install solar panels on your home and how much it could save you over time are:

  • Incentives: One thing that can reduce the cost of your solar project is the solar investment tax credit (ITC), which is a tax credit that lets you deduct from your taxes a percentage of the project cost. You can also save on your power bills, which can generate an average of $22,000 of savings over 20 years.
  • The amount of sunlight your home gets: Thanks to Williamston’s very high amount of average daily sunlight, you should be able to save a lot on your electric bills.
  • The type and model of solar panels you’re planning on getting: More efficient models are more costly, so that will shape your budget for your solar project.
  • Your household's power bills: Due to very high monthly electricity bills in Williamston, you could save about $1,500 a year with solar.

Even though a solar panel system costs a sizable chunk of money upfront, it can save you thousands of dollars over time. The question of how much, though, depends on a number of factors, such as the size of your house and your current power bills.

Environmental Impact of Switching to Solar in Williamston

Installing solar panels is a good way to do your part for a more sustainable future.You may be trying to figure out – how much does going solar do for the planet anyway? How much energy you use is a key factor to keep in mind. The more energy you use, the larger your impact when you switch to solar energy.Since solar panels don’t release greenhouse gas emissions into the atmosphere when producing electricity, they’re a good swap for traditional energy sources.

Since solar power is abundant and produces electricity without releasing carbon emissions, making the switch to solar power is one easy step you can take to help the environment.
