Energy is essential to everyone's life no matter when and where they are. This is especially true in this new century, where people keep pursuing higher quality of life. Among different types of energy, electric energy is one of the most important that people need every day. It is now a globally accepted reality that electrical energy is fundamental for social and economic development. Unfortunately still one third of the world's population lives in developing and threshold countries and have no access to electricity . It has been estimated that the world population will reach 8 billion by 2020 . The statistic shows that the population growth is mostly in developing countries where most of the people live in remote and rural areas. So, to supply the electricity requirements for them, the extension of utility grid is complicated and expensive due to geographical, economical and social barriers. Up to now, mostly diesel generator sets are used for rural electrification. This is not a good solution since, the fuel, maintenance cost is expensive, and it is also not environment friendly. In such circumstances, an alternative is to use locally available renewable energy sources.
