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.
