Modelling and simulation of Λ-ridge concentrator system using commercial PV modules

Abstract

This paper presents the Λ-ridge and V-trough concentrator system with low concentration ratio applicable in independent power supply systems (e.g. chalets, road signs, traffic lights, street lamps, industrial cameras, CCTV), of an outpower not exceeding 500W. Actual area of photovoltaic modules, which doesn’t exceed 3m2 constitutes important parameter in this kind of construction. Small external dimensions and relatively light weight are the crucial principles of constructing Λ-ridge concentrator system. The performance of the system and the amount of energy produced constitute key factors for such restrictions. A series of simulations was conducted enabling evaluation of the efficiency of the presented systems depending on their technical parameters and weather conditions.
