Stand-alone photovoltaic system for an emergency health clinic

Abstract

. This paper presents a study and design 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 the four seasons are assumed. The PV system is

optimally sized to be an optimal economic system. Homer

software is used as the sizing and optimization tool to determine

the size and specifications of photovoltaic system components,

system cost and estimation of corresponding produced electrical

energy. The results show that the sizing of PV stand-alone

system depends on the load data, the solar resource data and the

investment cost of system components. Also it is found that

providing electricity to the emergency health clinic using PV

system is very beneficial and economical, especially

considering the decreasing prices of PV systems and their

increasing efficiencies and reliability. They have also the

advantage of maintaining a clean environment.
