Here’s what you need to know about the price of solar panel systems in the Palmetto State.

Understanding The Price For A Solar Power Install In South Carolina

For most homeowners in South Carolina, the average solar panel installation will pay for itself in 7 years. That is to say that the length of time it takes for a solar install to produce energy equal to the financial equivalent of how much it costs to install is about 7 years. Payback period is also referred to as return on investment (ROI).

How did we get to the 7 year ROI figure for a home solar install? Our calculations are below.

A standard roof-mounted 8 kW solar energy system will produce approximately $1,594 dollars in energy each year. This assumes a $0.14/kWh value based on costs from SCE&G.

Average Cost Of Going Solar In South Carolina

Using a cost of $3.25/watt we have a gross cost of $26,000 for an 8 kW solar install.

A 30% Federal tax credit is available for solar installs until the end of 2019. 30% of $26,000 equals $7,800, and we can deduct this from the gross cost since the tax credit is money you receive from the federal government on your income taxes. $26,000 – $7,800 = $19,600

A 25% South Carolina tax credit is also available for solar installs. 25% of $26,000 is $6,500 dollars. And just like the Federal tax credit, we can deduct the SC solar tax credit from our gross cost. $26,000 – $7,800 – $6,500 = $11,700

So your net cost for an 8 kW solar system in South Carolina, that is the cost after federal and state tax credits, is just $11,700 dollars.

And as we said before, the financial value of the energy produced by an 8 kW solar panel system in 1 year is equal to approximately $1,594 dollars.

$11,700 dollars net cost / $1,594 dollars worth of energy produced each year = 7.34 years, or 7 years and 4 months until the solar panel installation pays for itself.

Final Notes On South Carolina Solar Costs

A solar panel system can be designed to offset 100% of your annual electricity costs. Instead of paying the local utility for power, you can generate your own electricity from solar panels. Going solar allows you to be energy independent and save money. The above example for an 8 kW solar panel install is an average system, but you may need more or less panels depending on your energy usage and habits.
