Energy cost calculations for a solar PV Home System

Energy costing for a Solar Home System has been presented here considering the main cost components. It has been identified that the cost of solar PV panels, bank interest rate, cost of battery and its longevity plays the most important role in determining the energy cost. Average solar insolation is also taken into consideration and the results show that contribution of the storage battery towards the total cost of energy is significantly higher than that of the solar PV panel.
