Going solar? Good call. It’s the right choice for your pocketbook and for the climate. If everyone in South Carolina used solar power, it would take 74 billion pounds of carbon out of the atmosphere every year—according to the EPA’s greenhouse gas calculator, that’s the equivalent of planting a forest that would cover all of the state.
Solar power isn’t yet a big part of the energy mix in South Carolina. Nationally, the state ranks #42 in solar energy use.
Solar Energy Pros And Cons
The biggest advantage of solar energy? The cost—$0. For the average South Carolina household, generating all their own electricity with solar would save $1,773/year. Also, you’re doing a favor for the next generation. Instead of relying on CO2-spewing coal plants and dangerous nuclear plants, which produce most of South Carolina’s electricity, you’ll be producing your own clean, renewable energy. In South Carolina, residential customers like you account for 23.1% of the state’s total energy consumption.
The disadvantages: The cost of installation. The average solar installation costs around $20,000. Incentives like South Carolina’s Solar Tax Credit, which allows taxpayers to claim a deduction of 25% of the cost of a solar heating or solar energy system, and the U.S. Residential Renewable Energy Tax Credit can bring the overall cost down.
How Many Solar Panels Do I Need For My Home?
The average South Carolina family uses 39,567 watts of energy on an average day. And, on average, they’ll get 4.75 hours of sweet South Carolina sun each day. So, to get enough energy to keep the power running all night, they’ll need their solar power array to generate 8,330 watts of energy per hour while the sun’s out.
Assuming they go with 250-watt solar panels, the math is simple. 8,330 watts/hour divided by 250 watts/panel = 34 panels needed.

Solar Trends In South Carolina
South Carolina lags behind its neighbor North Carolina in solar development, but could catch up with its northerly cousin by continuing to improve its solar and renewables policy.
South Carolina Solar Policy
South Carolina has a modest renewable energy portfolio standard: the state’s goal is to have utilities voluntarily generate 2% of their electricity through renewable resources.
South Carolina allows its utilities to offer net metering to their customers, but the policy isn’t mandatory, making the policy much weaker than most states’. In most states, net metering requires that utilities pay homeowners who go solar for the energy they create—crediting their accounts for solar energy they generate and use, and rebating them for energy they send back to the grid.
South Carolina Solar Projects
Furman University in Greenville is building a 743 kW photovoltaic project that will reduce the school’s fossil fuel emissions by 3%.
The South Carolina Electric & Gas utility is building a 10 MW plant in Ridgeland.
In June 2017, Columbia Metropolitan Airport announced the completion of a 5-acre solar panel array. The 1.38 MW solar project is expected to produce bill credits worth $250,000.
By the end of 2019, Adgen Solar plans to have a 74 MW solar project complete for Aiken County. The solar facility is expected to produce enough solar energy for 15,000 homes.
In June 2017, Southern Current announced that their next solar project will be in Hampton County. The facility is expected to cost the solar company $2.5 million.
South Carolina Solar Advocates
South Carolina Solar Council is an advocacy group that works with businesses, policymakers, utilities, and solar users.
