The photovoltaic system has a difference economic viability according to the economic variables such as the amount of electricity used in the residential building. Therefore, in this study three cases of amount of used electricity such as 351kWh, 400kWh, 500kWh/month in the residential building are analyzed to evaluate the economic viability of photovoltaic system by calculating payback period. In calculating the payback period, the major factors such as initial cost, government support money, interest rate, price rate, electricity charge rate and others are included. And besides, considering the uncertainty in the future risk analyses are also performed using the Monte Carlo simulation. |
