Cost of solar panels in South Carolina

The cost of solar panels in South Carolina depends on several key factors, including the size of your system, its configuration, the components, and your local labor and permitting costs. Solar system sizes are measured in dollars per watt, but system sizes are shown in kilowatts (kW). There are 1,000 watts for every kilowatt, requiring some math to understand your potential cost and system size. Solar panel systems are a custom product, so every system will differ based on a household’s needs. 

According to the Lawrence Berkeley National Laboratory, the average U.S. solar system is 8.6 kilowatts (kW) and costs $3.67 per watt. Based on these estimates, most solar panel systems cost roughly $31,558 in total.

Based on state data from Find Energy, the average solar system size in South Carolina is 9 kW. The state’s average price per watt is $3.45, meaning a solar system would cost around $31,050 before factoring in South Carolina solar incentives and tax credits. The following is a breakdown of how we calculated the average South Carolina solar panel cost:

($3.45 X 9 kW) X 1,000 = $31,050

The average solar system size and price per watt varies by state. Some states consume more electricity in a month, so the average system size is larger to account for higher usage. South Carolina, for example, has a higher average monthly usage than the U.S. average, likely because of the state’s hot summers. The following table compares U.S. solar averages to the average size and cost of solar panels South Carolina residents can expect to find when getting quotes.

System sizePrice per wattInstalled cost
South Carolina9 kW$3.45$31,050
U.S.8.6 kW$3.67$31,558

Solar panel systems are customized for your home, and the price will vary by size. A solar system’s size depends on the number of solar panels included. Using the average $3.45 price per watt from Find Energy, the following table shows the estimated cost of solar panels in South Carolina for a range of system sizes, including the number of solar panels you could expect for each size.

Free solar panels in South Carolina scam

There are no legitimate incentives or programs offering free solar panels in South Carolina. However, you may hear promises of installing solar panels for free from door-to-door salespeople or sales calls on the phone. Most likely, anyone offering free solar panels in South Carolina is a scammer. Solar scams are more common as home solar systems rise in popularity nationwide. While some credible installers do employ door-to-door sales people, you should confirm a person’s identification before discussing your personal information with anyone offering free solar panels. 

Some solar installers offer solar loans with no down payment or upfront cash requirements. While a zero-down loan is a more credible way to acquire solar panels without paying anything upfront, keep in mind that a loan does not mean you are getting solar panels installed for free. Some zero-down loans come with high interest rates or unfavorable terms, so be sure to read the details of a loan agreement before signing a contract.

Are solar panels worth it in South Carolina?

Electricity prices have risen significantly nationwide in recent years. Data from the Energy Information Administration (EIA) shows U.S. energy rates rose 10.7% from 2021 to 2022. Electricity prices in South Carolina increased by approximately 9.7% from 2021 to 2022 and have continued to rise in 2023.

Rising energy prices mean you could save even more now by investing in solar panels in South Carolina. Based on the average 2022 energy rate of 14.11 cents per kilowatt-hour (kWh) and usage of 1,078 kWh per month, the average South Carolina resident spends $149.99 per month on electricity bills. If you install solar panels that generate enough energy to power your home throughout the year, you can save almost $1,800 annually on energy bills.

Using the average yearly energy bill and cost of solar panels in South Carolina, the typical solar payback period for a solar system is approximately 12 years. After you achieve a return on your investment, you’ll continue to incur savings for years to come. Here’s how we calculated the average solar payback period in South Carolina:

(Total system cost − 30% tax credit savings) ÷ Annual electricity bill costs = Payback period

$21,735 ÷ $1,799 = 12 years

The best South Carolina solar incentives and rebates

While South Carolina solar panels are a significant financial investment, solar incentives at the federal, state, and local levels exist to help homeowners offset the cost of solar panels.

At the federal level, the Residential Clean Energy Credit offers a 30% tax credit for residents who purchase solar panels for their primary or secondary homes. Based on the average cost of solar panels in South Carolina, the federal solar tax credit would provide around $9,315 in credit when you file your federal tax return. You can combine the federal tax credit with other state and local solar incentives. SaveOnEnergy can help you learn more about the how to apply for the federal tax credit.

South Carolina offers a statewide 25% solar tax credit for the cost of your solar panels. The South Carolina solar tax credit has no expiration date, and you can claim up to $3,500 or 50% of your maximum tax liability. Other state solar incentives include South Carolina’s net metering policy and credits and rebates offered by local utility companies.

Why choose solar in South Carolina?

There are several key benefits to installing solar panels on your home. Some of the most common benefits that attract residents are reduced energy costs, greater energy independence, and a smaller environmental footprint.

Lower energy costs

For many residents, one of the most important benefits of installing solar panels in South Carolina is lower energy costs. Based on the average energy bill in South Carolina, traditional electricity could cost you nearly $1,800 per year. However, when you rely on solar to power your home, you can reduce or almost eliminate those electricity bills. If you keep your solar system grid-tied (most customers do), you’ll still incur some connection fees from the utility company, although these fees tend to be relatively minor compared to your savings.

Increase energy independence

Solar panels can also give homeowners more energy independence, meaning you won’t solely rely on the traditional electricity grid to power your home. When you have energy independence, you don’t have to worry about price hikes when energy demand is high. Stored energy from a solar battery can help protect your home against power outages due to storms or downed power lines.

Go green

Traditional electricity generation emits carbon dioxide into the atmosphere, contributing to climate change. Solar power is a clean and renewable energy source, so producing it doesn’t emit the same harmful pollution. As a result, switching to solar panels can reduce your home’s environmental footprint.

Financing South Carolina solar panels

If you’d like to invest in South Carolina solar panels, you can choose from various financing options, including a cash purchase, loan, lease, or power purchase agreement.

While each option has unique advantages, buying your own panels is the most cost-effective. It allows you to take full advantage of solar incentives, which can significantly reduce your costs and lead to long-term savings. You may also increase your home’s resale value by $15,000 on average, according to findings from the Department of Energy (DOE). Leasing your solar panels is less expensive up front, but you won’t be eligible for most solar incentives and your home value won’t increase because you don’t own the panels.

South Carolina solar panel companies

As green energy becomes more prevalent, the number of South Carolina solar panel companies will likely increase. When searching for the best South Carolina solar panel company, be sure to thoroughly research all your options. For starters, it’s important to know which financing options an installer offers since this could help you narrow your search immediately. Read reviews, ask for customer references, and research the company’s history before signing a contract. You should also discuss the timeline for installation as this could help you narrow down your options.

What to look for in a solar contractor

Your solar installer plays a critical role in setting you up for success with your South Carolina solar panels. The right installer will do more than just install your system — it will help you make financing decisions, choose the right equipment, and plan everything from start to finish. That’s why it’s essential to find the right fit in a solar contractor.

Here are a few things to consider as you compare your options:

  • Experience and licensing: With the explosive growth of the solar industry, there are a lot of new players in the business. But experience matters, and proper licensing is even more important. Look for fully licensed, bonded, and insured contractors with a few years of experience planning and installing solar panels in South Carolina.
  • Service reputation: Don’t simply enter a contract with an installer before receiving multiple opinions. Ask around and read reviews to find out how others have fared with contractors you’re considering.
  • Transparency in communication: Solar panels are a big investment, and you deserve to understand the process and know what’s going on at every stage. Look for installers offering full transparency on the process to keep you in the loop.
  • Pricing: The cost of solar panels in South Carolina varies widely based on a number of factors. It’s best to seek out multiple quotes for comparison and consider the pricing information on this page to ensure your cost makes sense.

Important solar installation factors to consider

Although solar in South Carolina can be a great investment, there are a few things to consider before you install solar panels on your home:

  • Your roof: According to the Department of Energy, solar panels work best on south-facing roofs with slopes between 15 and 40 degrees. If your roof is in poor condition, you may need a replacement before installing solar panels. Roof repairs or replacements could significantly impact how much it costs to install solar panels.
  • The amount of sunlight your home gets: Solar panels require direct sunlight to produce energy, meaning they’re most effective if your roof is not shaded by obstructions to sunlight. Keep in mind that the amount of sunlight your roof receives could fluctuate throughout the year, depending on your tree coverage.
  • Your neighborhood: If you have a homeowners’ association in your neighborhood, there may be restrictions or required approvals for solar panels. Your solar installer can help you navigate the requirements in your neighborhood.

Solar power FAQs

  • Solar power can provide huge savings, but it’s not right for everyone. When deciding if solar panels are right for your home, consider your energy usage habits, electricity costs, and how much direct sunlight your home gets. It’s important to calculate your typical energy consumption  to see whether switching to solar would be a worthwhile financial decision for you.

  • Solar panels aren’t free, but there are significant opportunities to reduce solar panel costs in South Carolina. Apart from the 30% federal tax credit available to everyone who purchases a system, South Carolina also offers a state tax credit, various utility rebates, net metering, and a property tax exemption.

  • If you’re in the market for a solar panel installer, SaveOnEnergy can help. Enter your information in our solar estimator to understand your potential savings and connect with a solar installer in your area.

  • Solar panels themselves don’t store energy — they capture it to be transformed into electricity. To store solar power that you don’t use immediately, you’ll need a solar battery. This component allows you to make the most of your solar panels by storing energy to use during power outages or off peak periods.

  • Solar panels have an average lifespan of between 25 and 30 years, but they could last even longer if you keep your system maintained. South Carolina tends to experience hot summers and occasional hurricanes. Solar panels are made to withstand extreme conditions, although higher-quality panels will likely last longer than cheaper modules. If you are concerned about whether the climate in your area will impact the lifespan of your solar panels, search for solar panels with strong manufacturer or product warranties.
