Abstract: This paper gives the feasibility analysis of PVBattery
system for an off-grid power station in Sohag city.
Hybrid PV-battery system is used for supplying a
combined pumping and residential load. A simple cost
effective method for sizing stand-alone PV hybrid systems
was introduced. The aim of sizing hybrid system is to
determine the cost effective PV configuration and to meet
the estimated load at minimum cost. This requires
assessing the climate conditions which determine the
temporal variation of the insolation in Sohag city. Sizing
of the hybrid system components was investigated using
RETscreen and HOMER programs. The sizing software
tools require a set of data on energy resource demand and
system specifications. The energy cost values of the hybrid
system agrees reasonably with those published before.
