Design and Performance Analysis of Commercial Reflectors Attached to Three Types of PV Module

Abstract

Solar reflectors could be one of the cheapest and easiest ways to increase the power generated from the PV modules. Low-cost reflecting materials are a good solution. (Less than 1$ US dollars for each square meter), the type of commercial reflector is (semi-diffuse, flexible reflector made of an aluminized PET laminate). It's lower in cost than adding more solar PV panels. After modeling a Simulink-MATLAB test module, to be derived from the real input factors. [1]. An implementation of the PV system was already done, and long-term measurements were registered for 1 year. Based on the environmental conditions in Egypt, the measured components of hourly dropped irradiance and temperature, and some other meteorological records were collected from June 2020 till May 2021. This research represents practically the differences in the power ratio of 3 types of PV modules, - (Polycrystalline, Thin film, and Monocrystalline) - before and after applying reflecting panels. The values of short circuit current ISC and open-circuit voltage VOC were measured under different conditions. Data can be used to validate the comparison between the theoretical and practical calculations of the output power, also to find the range of variation in the generated power for the 3 types of PV modules to be operated under the Egyptian environmental conditions. This paper founds that the measured lowest and highest average power ratio, for the total output power of PV system, were (1.2157 & 1.3185 respectively) which means the total output yield power was increased by a range varies between 21%-31% referenced to the basic output.
