Methodology: How We Ranked the Best Solar Companies in Duncan

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


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 Duncan

Even though solar panels can help save you a decent chunk of change on electricity bills over time, it’s important to know the startup 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:

  • average energy usage: The more energy your household consumes on average and the higher your current power bills are, the more money you could save by making the switch to solar.
  • Incentives: Along with the federal Solar Investment Tax Credit (ITC), which lets you deduct 0 of your overall installation cost, your 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 $21,000 over the first 20 years with your system, too.
  • The amount of sunlight your rooftop gets: Due to Duncan’s very high amount of average daily sunlight, you should be able to save a lot on your electricity bills.
  • The model of solar panel system you can afford: This hinges on how much you’re willing to spend upfront.

Even though a solar panel system costs a sizable chunk of money upfront, it can save you a considerable amount over the lifespan of your panels. The question of how much, though, depends on a number of factors, including the kind of solar panels you get and your current power bills.

Environmental Impact of Switching to Solar in Duncan

One of the reasons so many are thinking of installing solar panels is to help lower their environmental impact.But you may be wondering – how much exactly can you help by using solar power? In a city like Duncan where energy use is particularly high, installing solar panels is a fantastic plan for households who want to do their part for the environment.Since solar panels don’t release carbon dioxide emissions into the atmosphere when producing electricity, they’re a good substitute for traditional energy sources.
