Costs and Incentives

Solar electric systems cost on average $3 to $5 per watt installed, but new technologies are bringing the costs down every year. South Carolinians with sufficient tax liability can take advantage of federal and state tax credits for the purchase and installation of a solar electric system to reduce the cost. After these tax credits are applied, the average 4-kilowatt (4,000-watt) system will cost an estimated $9,000. However, the cost per watt usually goes down as the system size increases. Keep in mind that costs may vary by installer and are subject to change at any time.

IMPORTANT NOTE ABOUT TAX CREDITS: Tax credits only apply if you owe enough in taxes to balance your credit. You’ll reduce your tax liability, but you will not receive a check if you do not owe taxes. Consult your tax advisor.
