How Solar Payback Works in Vermont
Solar payback period is the time it takes for your cumulative electricity savings to equal the total cost of your solar system. In Vermont, the calculation depends on three key factors:
- System cost — $3.30/Watt average in Vermont
- Electricity rate — $0.195/kWh average utility rate
- Solar production — 4 average peak sun hours/day
After the payback period of 15.1 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.
