Methodology: How We Ranked the Best Solar Companies in Cayce

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


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 Cayce

Solar panels run off a free energy source — the sun — but to take advantage of this you will first need to pay to set up your panels.The cost and possible savings vary depending on a few important factors such as:

  • How much sunlight your roof gets: If your rooftop doesn’t see much direct sunlight, your solar panels won’t be able to generate as much energy, which will leave you with lower savings on electricity bills than a roof that gets plenty of sunlight.
  • Incentives: The federal solar investment tax credit currently lets you lower your taxes by 0 of the project cost. Your state and even local utility companies may also have various incentives that you can take advantage of. Additionally, you can save about $24,000 over 20 years on your utility bills, not including incentives.
  • How much energy your household consumes: Households that consume lots of energy each month may require more solar panels and, consequently, be more expensive, but will also enjoy more savings over time.
  • The type of solar panels you’re planning on getting: Higher-efficiency panels are more costly, so that will affect your budget for your solar project.

There are lots of wonderful benefits of solar despite the initial cost of installation. It can help the planet and your wallet. In addition, it can boost the value of your home, resulting in even more benefits if you choose to sell your home later.

EcoWatch's Cayce, SC Solar Company Rankings FAQs

Which solar company is the best near me?

The highest-rated local solar company in Cayce is Renu Energy Solutions, with a rating of 4.60 stars.

What is the negative environmental impact of solar panel manufacturing?

Solar panels can be bad for the environment when manufacturers use toxic chemicals when they’re made. Chemicals can make solar panels difficult to recycle safely once they’ve reached the end of their lifespan. Making solar panels requires a lot of energy as well. The energy payback period is about 1 to 4 years.

Are solar panels worth it?

Solar panels can be a good investment for many homeowners, but honestly, they might not be worth it for everyone. If your home doesn't get a lot of direct sunlight or your energy bills are already pretty low, solar panels might not be for you.

How often do solar panels need to be replaced?

On average, solar panels can last about 25 to 30 years. Some even last up to 50 years, but efficiency decreases by about 0.8% each year. You can choose to replace them sooner if you want to maintain a higher amount of energy production.
