Analytical Model of Non-Imaging Planar Concentrator for the Application in Dense-Array Concentrator Photovoltaic System

Abstract

Instead of using numerical simulation method that is relatively slow if accuracy is required, an analytical model has been proposed to analyze the optical characteristic of Non-Imaging Planar Concentrator (NIPC) for the application in dense-array concentrator photovoltaic (DACPV) system. Several trigonometry equations have been solved to determine the maximum solar concentration ratio, uniform illumination area and energy within the uniform area by varying the focal distance. The concentration ratio can range from 337 to 422 sun sand the energy percentage decreases from 68% to 50 % within the area that ranges from 82 cm2 to 52 cm2. According to the results, the analytical model is capable of obtaining the NIPC's three important design criteria within an error of at most 4.7 % compare with the numerical simulation method. As a conclusion, analytical model is capable of offering an express method to designer for optimizing the performance of the DACPV system.
