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
While solar panels can help save you money on utility bills over time, it's important to know the startup costs. Some important things that determine the upfront cost and potential savings over time include:
- The amount of sunlight your home gets: Because of Duncan's very high amount of average daily sunlight, you should be able to save a lot on your power bills.
- Choice of solar panels: The type of solar panels you are interested in getting 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 go with a higher number of more affordable panels.
- Electricity consumption: The average household in Duncan uses a lot of energy, and as a result may see more savings on electricity bills than other places.
- Incentives: Tax-paying citizens who install a solar energy system this year can save 30% of their installation costs by taking advantage of the federal solar investment tax credit. You can also save about $21,000 on your utility bills over 20 years not including incentives.
Solar is a rewarding investment for most homeowners. You can produce your own energy instead of paying for it from a utility company and make use of solar incentives, all while helping the planet.

EcoWatch's Duncan, SC Solar Company Rankings FAQs
Which solar installation company is the best near me?
In Duncan, Elite Roof and Solar - Boone is the most reputable local solar company. Our team of experts rates it 5.00 stars, so it's a good choice if you're looking to install solar panels on your roof.
What are a few of the biggest pros and cons of installing solar panels?
A few of the biggest pros are that it decreases your electricity bills, it's environmentally friendly, and it provides a decent return on your investment (ROI). The most notable cons are that solar panels don't work as well when there's limited direct sunlight, they cost a lot upfront and solar panels aren't always aesthetically pleasing.
How long does it take for solar to pay for itself?
Solar panels typically pay for themselves in about 8.6 years, but your solar payback period will vary depending on your utility costs. The higher your typical energy bill, the faster your solar panel system will recoup your installation costs.
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 are completely unusable. What this means is their energy production will have decreased by about 0.8% each year since installing them. You can choose to replace them once you've had them for that long or you can continue to use them at a lower efficiency after that time.
