Optimizing the Solar Array of Stand - Alone Photovoltaic Energy Systems as a Function of Time and Load Profiles

This paper presents a proposed novel technique in which an accurate optimum design of the solar array (SCA) can be attained. It depends on an hour-by-hour approach with different daily load profiles. A generalized mathematical formula has been developed for, sizing of the solar array given the geographical and one year's insolation data for a particular site in EGYPT. This approach can reduce the required size compared to other methods using the same tilt angle.
