The state of solar power in Charleston, SC

The state flag of South Carolina has a palmetto tree with a crescent moon above it. However, residents might want to consider changing that moon to the sun. The state is one of the shining stars nationally when it comes to solar power with a projected growth of 1,571 MW over the next five years.

Charleston is a particularly attractive option for solar panel installation, thanks to its above-average amount of sunlight and significant opportunities for savings. According to Project Sunroof, homeowners in Charleston stand to save $11,000 over the 20-year life span of a solar purchase.


How much solar power does Charleston, SC produce?

The state of South Carolina produces 510.5 MW of solar energy per year, as of 2018. That represents an enormous step forward, considering it produced 15 MW in 2015 and less than one MW in 2010. Today, South Carolina is 18th in the country in overall solar capacity.

It's challenging to know precisely how much solar power Charleston produces. There aren't any disaggregated statistics to show generation on a city by city basis. While Charleston likely produces a fraction of the overall solar energy, it ranks as the tenth best city in the nation for savings from solar panel installation.

Is solar feasible in Charleston, SC?

Yes, solar power generation is feasible in Charleston. The city sees an average of 209 sunny days per year, which is above the national average of 205. It also has a UV index, which measures the city's exposure to ultraviolet light, of 5.1 compared to the 4.3 for the rest of the United States.

April to October are the sunniest months. During this period, homes in South Carolina get a little less than six hours of pure sunshine. That figure dips in the winter when the Northern Hemisphere is further away from the sun. Furthermore, the state has made significant investments in connecting more people with solar power. Currently, there are more than 100 manufacturers, installers, and developers in the industry.
