How Solar Payback Works in North Carolina
Solar payback period is the time it takes for your cumulative electricity savings to equal the total cost of your solar system. In North Carolina, the calculation depends on three key factors:
- System cost — $2.80/Watt average in North Carolina
- Electricity rate — $0.126/kWh average utility rate
- Solar production — 4.9 average peak sun hours/day
After the payback period of 16.1 years, your solar panels continue generating free electricity for 15-20+ more years. With utility rates historically increasing 2-4% annually, your actual savings will likely exceed these estimates.
