How Greenville's Climate Affects Solar Installation
In Greenville's market, a typical residential solar installation produces 4–5 peak sun hours/day, with a 10kW system generating 14,000–18,000 kWh/year. At average electricity rates, this offsets $1,400–$2,200/year in utility costs before net metering export credits. The 30% federal Investment Tax Credit (through 2032) reduces the after-incentive cost of a $20,000 system to $14,000, achieving payback in 7–10 years in most markets. Most systems are financed at $0 down with monthly payments below the utility savings.
