The worldwide potential of Photovoltaic (PV) systems for off-grid infrastructure in developing areas is very wide. It is estimated that around 1 billion people are served by health facilities lack the access to reliable electricity. This master thesis simulate and optimize a sustainable and cost effective design system, and evaluates international experience in off-grid PV technologies for off-grid health facilities in developing countries. The lessons learned from international experience in this field show that, the sustainability of off-grid PV systems for health facilities is realized through designing an institutional and regulatory framework for such international and national programs. Investigation and elaboration energy demand assessment for Al-Ja{u2019}adh, a medium size health facility in Yemen shows, that the daily load consumption is 19.4kWh/day. Accordingly, a typical autonomous PV system was designed and simulated to supply the daily load with the energy. Optimization of the designed system on HOMER through applying of demand side management technic shows significant results regarding reducing the rated capacity of PV array and increasing the lifetime of battery bank. Investigation of the energy management of the design system was performed on MATLAB. These results lead in reducing the net percent cost of the systems and levelized cost of energy, as well. Modification of the optimized system through replacing of load improved performance of the system and reduced the total cost significantly
