The state of solar in South Carolina

South Carolina averages more than 215 sunny days* each year making it a prime location for clean energy. Though the state currently generates more than half of its power from nuclear plants,* the Solar Energy Industries Association (SEIA) ranks South Carolina 13th nationwide for solar energy and expects output to nearly double in the next five years.*


How much energy does South Carolina produce?

Currently, South Carolina generates 1,891.4 MW of solar energy through more than 23,000 installations, more than enough to power roughly 222,000 homes statewide.*

That said, the Palmetto State's potential remains largely untapped, according to Google's Project Sunroof. The study found that 80% of South Carolina's buildings feature solar-viable rooftops. With this in mind, South Carolina could generate nearly 20,000 MW of clean energy each year, the equivalent of removing 3.2 million passenger cars from the road or growing 387 million trees for ten years.*

Solar energy projects can vary as well, ranging from large-scale ventures like comprehensive installations and power farms to small consumer installations for individual homes.

What are the advantages of going solar in South Carolina?

Going solar in South Carolina comes with several far-reaching advantages. For example, South Carolina's Energy Freedom Act empowers you to install solar systems at your home or business while eliminating net metering caps,* allowing you to claim credits for excess solar energy your solar system produces.

The state also offers relatively low installation costs compared to other areas. As a result, you can expect to recover your costs in only seven to nine years. In addition, you can enjoy lifetime savings of more than $30,000 when you install an average-sized 6.3kW system in South Carolina.*

Finally, you can take positive action to ensure a healthier, cleaner future for the Palmetto State. Solar systems minimize your carbon footprint and improve local air quality by reducing the number of greenhouse gases released into the environment.*

How much does solar cost in South Carolina?SOUTH carolina solar

The cost of a home solar system can vary due to a range of factors, even in the same state. These include:

  • Shaded roof space

  • Local weather

  • Quality of the solar panels

  • Roof angle

To help you understand the price of going solar in your area, we've analyzed SunPower price quotes as well as quotes gathered by third-party sources for thousands of homeowners across the country.

In South Carolina, we found that the cost of owning a 5 kW solar system ranges from $13,300 to $32,400, or in other words, from $2.66 to $6.48 per watt—and that's before considering the benefits of any available tax credits or incentives.

Like the rest of the United States, the average cost of solar panels for a home in South Carolina has decreased by 80% over the last decade. The state also offers various incentive programs for qualifying residential and business property owners.

Homeowners who purchase their system as opposed to leasing it, can get a federal tax credit of up to 26% of the total cost of the solar installation.* In addition, you can claim a statewide 25% tax credit after installing a solar system at your home.

Local municipalities and utility companies may also provide added benefits for installations through net metering or financial rebates. Duke Energy and Santee Cooper, two of South Carolina's major utility providers, offer rebates worth up to $1.30 per watt of solar power your system generates.*
