South Carolina Solar Power Incentives

Current South Carolina Legislative Environment For Solar

While every State differs in their approach to renewable energy South Carolina is not classed as one of the more progressive States. Up until recently the State has no Renewable Portfolio Standard (RPS). This is a standard that each state sets with a mandate to have a specific percentage of energy generated by renewable resources by a specified date. This year South Carolina did set a RPS of only 2% to be reached by 2021. Included in the mandate is that facilities that are between 1MW and 100MW will generate 1%, while the other 1% is to be generated by facilities less than 1MW.

South Carolina does not have a Carve Out Policy as part of the RPS. A Solar Carve out is where the utility companies must produce a specified amount of their energy from the sun.

The State is also weak on its interconnection rules.

Incentives Available For South Carolina Solar

As of 2016 South Carolina has the 19th best solar power rebates.

Residents of South Carolina are now being offerd a $1/watt rebate of the cost of their solar panel system. This is being offered through Duke Energy. It is actually an excellent rebate compared to those in many other states. This rebate creates a $5,000 reduction of the cost of a $20,000 5-kW solar system.

Solar Performance Payments

This is a system that rewards solar system users for the amount of electricity that their system produces. The rewards come as either per kWh bonuses or solar renewable energy certificates. The bonuses go towards reducing the electrical bill, whereas the certificates are sold. It is not sure how long this particular incentive will last.

South Carolina does not offer any property tax exemption or any sales tax exemption for those having a solar system installed.

South Carolina Net Metering

Net metering allows those who are enjoying solar energy to sell back any solar energy that is not used to the utility company. In 2014 the State did mandate a new set of net metering rules. Basically what it entailed is homeowners getting a rebate at the end of each year for solar power that you generated in excess of what was used. There are some flaws in the rules that are currently being worked on.

Rebates / Tax Credits

There is the 30% Federal tax credit.

Plus, the State tax credit of 25% up to a maximum of $3,500 or 50% of tax liability. South Carolina ranks as the 10th best when it comes to this solar credit.

All of the rebates and incentives added together dramatically reduces the cost of the system.


While South Carolina may be somewhat weak in some area of solar power energy they are making steps forward and when you look at the substantial start up savings then the monthly savings going forward, now makes it a good time for those in South Carolina to make the switch over to solar.
