WHY GO SOLAR?

The Case for Solar in South Carolina

From your wallet to your community, solar energy delivers compounding benefits that grow stronger every year.

Energy Independence

  • SC is heavily dependent on out-of-state fossil fuels — solar changes that.
  • Solar + battery storage protects your home from grid outages and rate hikes.
  • Localize energy production at the home and community level.
  • Take control of your electricity — no more surprise bills from Duke Energy or Dominion.

The Real Conversation

A Car for Your Teen — or Freedom from Your Power Bill?

A New Car for Your Teen

5-year total cost of ownership

Vehicle purchase$28,000
Teen insurance (5 yrs)$13,200
Gas & maintenance (5 yrs)$12,000
Total invested$53,200

Result: A depreciating asset that adds another monthly bill.

A Solar System for Your Home

Similar investment, opposite outcome

9.5 kW system (gross)$28,500
Federal 30% ITC-$8,550
SC State Credit (25%)-$3,500
Net cost~$16,450

Result: Eliminates your electric bill — and pays you back in 6-8 years.

The difference is profound.

The average Columbia, SC household pays $156/month in electricity — $1,872/year, every year, forever. A new car for your teen costs about the same upfront as a solar system, but the car keeps draining your wallet with insurance, gas, and maintenance. Solar is the one major home investment that directly erases a monthly bill, increases your property value, and keeps generating returns for 25+ years.

Columbia, SC averages: 1,069 kWh/mo • $156/mo electric bill • 4.8 peak sun hours/day • Recommended system: 9–9.5 kW
