Methodology: How We Ranked the Best Solar Companies in Union

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


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 Union

Solar panels run off a free energy source — the sun — but before you can take advantage of this you will need to pay to set up your system.There are quite a few factors you should consider when trying to determine the overall cost and how much you can save, including:

  • The make and model of solar panels you want: More efficient panels cost more, so that will affect your budget for your solar project.
  • Where your home is: This influences how much sunlight your roof gets, which helps determine how many panels you need.
  • How much power your household needs: If your home regularly uses a lot of energy, you'll benefit more from switching to solar.
  • Incentives: Something that can make your solar project cost less 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 a decent amount of money on your energy bills, which can generate an average of $22,000 of savings over 20 years.

Solar is a rewarding investment for most homeowners. You can make your own electricity instead of paying for it from a utility company and benefit from solar tax credits and rebates, all while helping the environment.

Environmental Impact of Switching to Solar in Union

Many want to do their part for the planet, which often is the main reason they’re interested in installing a solar system.But you may be wondering – how much exactly can you help the planet by making the switch to solar? One thing to consider is your overall carbon footprint. For example, if you have a long commute time and have an electric vehicle, you can install solar panels on your home to power your EV and therefore help offset your carbon emissions.Although solar panel production releases carbon dioxide emissions, the panels make up for it by considerably decreasing the amount of CO2 you would have released if you still used nonrenewable energy. In Union, you can reduce your carbon footprint by 60 pounds a year with solar panels. Since solar power is plentiful and makes electricity without releasing carbon emissions, installing solar panels is one easy step you can take to help preserve the environment.

EcoWatch's Union, SC Solar Company Rankings FAQs

Which solar panel installer is the best in Union?

In Union, Renu Energy Solutions is the best local solar company. Our team of experts rates it 3.00 stars, so it's a solid choice if you're looking to add solar panels to your roof.

Are solar panels actually eco-friendly?

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

How long does it take for solar to pay for itself?

Solar panels usually pay for themselves in about 10.3 years, but your solar payback period will depend on your utility costs. The higher your typical energy bill, the quicker your solar panel system will pay for itself.

What is the efficiency of solar panels?

Usually, solar panels are about 15 to 25% efficient, which means they can convert that percentage of the sun’s energy into usable electricity.
