    An energy shortage is continuously deteriorating. The main cause is the population and economic growth which results energy demand higher than energy consumption. In 2011, the total primary energy consumption has increased about 3.5% from the previous year [1]. Increasing energy consumption shown in Fig.1 According to energy shortage and environmental issues, it seems that for today and tomorrow, the priority choice of energy resource to produce electricity [2],[3]. Due to untercenties of renewable energy resource for electricity generation that does not match the energy consumption rate, therefore to achieve stability in electricity supply, the appropriate technology which able to store electricity is required. The battery is an electric power supplies that is widely used. Battery is a device that stores energy for the electric power supply [4],[5]. Batteries are used in the electric energy storage for stand-alone photovoltaic systems during no sunlight [6]. The popular battery which is widely used is lead-acid battery, that is not expensive. However, it has some limitions : high maintenance, short lifetime, low capacity and low power density per unit weight. Trend of battery technology is focused on higher efficiency development with the proper size, shape, weight and low maintenance is also required. Battery is developed various features such as nickel metal hydride (Ni-MH), lithium ion (Li-ion) batteries etc. The objective of the research is to compare the economic cost of lithium-ion batteries with lead-acid batteries in stand-alone photovoltaic system.
