Current solar incentives and tax credits available in Charleston, SC

South Carolina solar tax credit

Charleston residents can take advantage of South Carolina's solar tax credit. The credit is equal to 25% of the cost of your solar installation. 

South Carolina state tax credit

South Carolina has a state solar tax credit that is equal to 25% of the cost of a system.

The 26% federal solar tax credit explained

The federal solar tax credit is equal to 26% of the total cost of installing solar panels on your home. The amount of the tax credit is then deducted from your federal taxes. You can claim the credit over several years if the amount you owe in taxes is less than the amount of your tax credit. You can only take advantage of the federal tax credit if you pay federal income taxes.

Keep in mind that the federal solar tax credit is set to step down at the end of 2021, falling from 26% of costs to just 22%. So, the best time to go solar is now, so you can maximize your solar savings.

How much will solar panels on my home save me?

The answer to this question depends on your electricity usage. Generally speaking, the higher your power usage, the greater your potential savings are from installing solar.

The average monthly electricity usage in South Carolina is about 1,155 kWh per month. However, you are most likely using a lot more than this since this average includes small apartments and condos.

The Charleston solar panel savings calculator uses our database of electric rates from local utilities to convert your monthly power bill into how much electricity your home uses. From there, the calculator can work out how many solar panels you need to offset your power usage, how much a solar system will cost based on prices of local solar companies, and the amount of money you will save on your electric bill.
