How Solar Payback Works in North Dakota
Solar payback period is the time it takes for your cumulative electricity savings to equal the total cost of your solar system. In North Dakota, the calculation depends on three key factors:
- System cost — $2.80/Watt average in North Dakota
- Electricity rate — $0.180/kWh average utility rate
- Solar production — 3.8 average peak sun hours/day
After the payback period of 14.6 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.
