Performance Measurement of Peltier Element Design using Solar Test Simulator Concerning Light and Temperature Parameters

Abstract

This study investigates the application of Peltier element technology for testing solar panels under varying environmental conditions, focusing on light intensity and temperature. A solar test simulator was used to design and implement the Peltier elements and the circuit was simplified by calculating the capacitor charging factor. This simplification aligns with the specific characteristics of the solar panels and offers a cost-effective approach to equipment development while delivering optimal results. The design, which incorporates surface temperature regulation via Peltier elements at adjustable distances, allows for the accurate simulation of varying light and temperature conditions on the surface of the tested solar panels. The voltage applied to the Peltier element directly influences the temperature it produces, measured in real-time during controlled temperature variation experiments. These measurements were conducted under three simulated sunlight conditions, allowing for detailed observation of the instantaneous voltage changes in the cooling element. The study created a Solar Test Simulator prototype designed for solar panel testing. The results demonstrate that the Peltier element-based system effectively controls temperature variations and accurately reflects the real-world performance of solar panels under diverse environmental conditions. The temperature measurements, taken across two solar panels with varying specifications, validate the effectiveness of this approach, making it a valuable tool for solar panel testing and optimization.
