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 are powered by a free energy source — the sun — but before you can take advantage of this you must first pay to set up your system. There are a few factors you should take into consideration when trying to figure out how much it will cost and how much you can save, including:

  • Electricity consumption: The average home in Union uses a lot of energy, and so may see more savings on electricity bills than other places.
  • How much sunlight your roof gets: If your roof doesn't see much direct sunlight, your solar system won't be able to make as much energy, which will give you lower savings on electricity bills than a roof that gets plenty of sunlight.
  • System size and type: Some models are more costly than others, so the one you decide on can raise or lower your initial investment. Plus, the more solar panels you need to buy, the more it'll cost.
  • Incentives: Along with the federal Solar Investment Tax Credit (ITC), which gives you a tax credit currently worth 30% of your overall installation cost, your state or local government may offer additional tax exemptions, credits or rebates that will help you save even more. Excluding incentives, you can save an average of $22,000 over 20 years with your solar panels, too.

Solar is a rewarding investment for most homeowners. You can generate your own power instead of paying for it from the grid and benefit from solar incentives and rebates, all while helping preserve the Earth.

Solar Incentives in Union

Switching to solar power has plenty of wonderful benefits. Not only can it help preserve the environment, but you can also save a good amount of money on your installation with various government incentives. No matter what state you live in, you can take advantage of the federal Solar Investment Tax Credit (ITC), which lets you claim 30% of how much you paid for your solar installation when you file taxes, reducing the amount of taxes you owe that year. Plus, there may be some local incentives you can benefit from too. You can find out about the incentives you can take advantage of in our article on solar incentives

Environmental Impact of Switching to Solar in Union

But you may be wondering — how much exactly can you help by making the switch to solar? In a city like Union where energy use is particularly high, installing solar panels is a fantastic plan for those who are eco-conscious.

EcoWatch's Union, SC Solar Company Rankings FAQs

Which solar company is the best near me?

The highest-rated local solar company in Union is Freedom Solar Power, with a rating of 4.01 stars.

What are the advantages and disadvantages of solar power?

The main advantages of solar power are that it can lower or, in some cases, 100% cut your electricity bills, raise the value of your home and cut back on your carbon footprint. The main disadvantages are that solar panels can be expensive to install, you may not see as many savings if you don't use a lot of electricity and whether you can install solar panels depends on your roof configuration.

Are solar panels worth it?

Solar panels can be a fruitful investment for most homeowners, but admittedly, they might not be worth it for everyone. If your home doesn't get enough sunlight or your power bills are already fairly low, solar panels might not be for you.

How efficient is a solar panel system?

Solar panel efficiency is the amount of energy from the sun that is converted into electricity. Most panels today have an efficiency rating of about 15 to 25%. If your panels are more efficient, you'll need less of them to meet your home's energy needs.
