EVALUATION OF PHOTOVOLTAIC MODULE EFFICIENCY BASED ON VARIOUS REFLECTIVE SURFACES AND ANGLE POSITIONS USING RESPONSE SURFACE METHODOLOGY

The depletion of traditional energy sources and the urgent demand for higher energy efficiency underscore the critical need for renewable energy solutions. This study explores strategies to enhance solar energy conversion efficiency by improving the performance of photovoltaic (PV) panels through the application of cost-effective and recyclable reflective materials, including Plexiglas mirror sheets and aluminum foil. By utilizing reflective materials to redirect additional sunlight onto the panels, this method enhances solar light capture and provides an accessible, cost-effective way to increase energy production. Experimental results confirm that the selected materials effectively enhance efficiency, demonstrating a measurable impact on photovoltaic panel performance. Response surface methodology (RSM) analysis highlighted that the mirror angle was the most influential parameter, with a 110° angle proving particularly effective in enhancing the energy output of the PV modules. These findings demonstrate that simple, low-cost solutions can significantly improve solar energy systems, paving the way for practical, scalable applications.
