Abstract
Solar energy is expected to play a very important role in meeting energy demands in the near future. Since it is a clean type of energy with a diversity of applications, decentralized nature and availability, solar energy will represent a suitable solution for energy requirements especially in rural areas. It is important to state that the use of solar energy in rural regions will protect this area from pollution, since the use of solar home systems avoids large amount of CO2 emissions . Photo means light , Voltaic means electricity . Photovoltaic means getting electricity from light . Photovoltaic (PV) system is able to supply electric energy to a given load by directly , converting solar energy through the photovoltaic effect . The system structure is veryflexible . PV module are the main building blocks , these can be arranged into arrays to increase electric energy production .
