Solar Power in South Carolina

With an average of 216 sunny days each year, South Carolina is an ideal place for those looking to tap into solar power and cut down on energy expenses. Ranking in the top 10 for residential electricity sales per capita, the state’s 70% of homes use electricity for heating, and nearly all homes relying on it for air conditioning contribute to this. Additionally, South Carolina provides an excellent state tax credit and net metering, helping to further reduce the initial costs.

South Carolina Solar Panel Costs

The average cost of a 5-kW solar power system in South Carolina falls between $15,000 to $25,000. This cost varies based on factors like the number of panels, labor, system configuration, and any permitting expenses. Keep in mind that this estimate doesn’t factor in tax credits or incentives.

Typically, it takes around 8.7 years to recover the initial investment through energy savings. However, this duration can vary depending on factors such as energy costs, sunlight availability, and the presence of incentives.

Federal Solar Investment Tax Credits

The federal solar investment tax credit is a beneficial incentive for those considering a solar energy system. This credit provides a 30% reduction of your taxable income and is applicable to various solar installation projects, including solar panels and solar heating systems. The federal government offers this credit to encourage the use of renewable energy sources.

South Carolina Solar Rebates and Tax Credits

In addition to the federal tax credit, South Carolina provides a 25% tax credit for the installation of a solar power system. The maximum credit is $3,500 or 50% of your state tax liability for up to 10 years, whichever is less. Some energy companies, manufacturers, and installers may also offer rebates.

South Carolina has a net metering policy where energy companies monitor your energy use. If you produce more energy than you consume on systems 20 kW or less, you can receive a credit.

Local Incentives

Net metering terms can differ based on coverage areas. Certain utilities provide a one-to-one credit, while others may charge solar customers more during peak periods and less during off-peak periods. Homeowners can utilize the Energy Saver tool to discover nearby incentives.

Net Metering in South Carolina

In South Carolina, both residential and commercial solar panel users can benefit from net metering. This program enables individuals to use their solar panels to generate electricity and transfer any extra power produced to the grid. The surplus energy can be utilized later or sold back to the utility company at a set price. 

This setup encourages the efficient use of solar energy and offers a financial incentive for adopting renewable energy systems.

Which Solar System Is Right for Your Home?

The best solar system for your home is the one that matches your energy needs and budget. Solar panel systems involve a significant upfront investment, but the costs can be recovered over time. Consider the location of the solar panels; they usually work best on the south side of a roof at angles of 30 to 45 degrees.

Energy storage is another factor to think about. Some systems offer battery storage options, which might mean an extra cost. In 2020, the average American household used 10,715 kWh. To completely offset energy costs, a home might need numerous solar panels, averaging 17.5 square feet each. Therefore, it’s essential to know your roof’s square footage and figure out the best placement for the panels.
