Sizing of Photovoltaic System A Case Study: Health Centre at Kenana Agricultural Area Seven

Abstract

Rural health service is an important national and international priority. However, the availability of electricity to support proper rural health services is less than adequate in many countries. In recent years the development of reasonably priced and reliable energy systems has made it possible to provide vaccines and other basic health care services in remote areas. A number of international, national, local institutions and private companies are now deploying renewable energy systems to rural communities in the developing world where health care in rural areas is a national priority. This thesis presents a study and sizing of a complete stand-alone photovoltaic (PV) system for providing the electrical loads in an emergency health clinic according to their energy requirements. Typical energy consumption daily profiles for Kenana area seven health center. The PV system is optimally sized to be an optimal economic system. Computer software is used to sizing and optimization tool to determine the size of photovoltaic system components, system corresponding produced electrical energy. The results were 74 solar modules (200watt), 32 batteries (12V, 180Ah), 1 Inverter (4825w, 48Vdc, 230Vac) and 1 charge controller (80A, 48Vdc). The results show that the sizing of PV stand-alone system depends on the load data, the solar resource data and system components.
