SCE&G offer a great net metering program to their solar customers in Mount Pleasant. Each kWh of unused solar production offsets the cost of another kWh your home draws from the grid at night or on a cloudy day. When more power in a month is generated than consumed for the grid each surplus kWh is still credited at the retail value. Credit can be applied to future bills within the same 12 month cycle or at the end of those 12 months be deposited into your account. With plenty of sunshine in Mt Pleasant net metering can make you some serious money.

South Carolina also allows you to claim up to $3,500 or 50% of your state tax liability (whichever is least) as a state tax deduction when you install solar. You may also claim 30% of the remaining costs after the state tax credit as a deduction to federal taxes. The federal solar tax credit has no size limitations and can be spread over many years. With about 40% of your solar system cost taken away in tax credits and a solid net metering plan you'd have to be crazy not to install solar in Mt Pleasant especially since utilities are trying their hardest to end net metering.
