Original abstract

Purpose: The purpose of this study is to investigate the influence of various environmental factors on the electrical performance and long-term efficiency of solar photovoltaic (PV) systems. This work aims to quantify the effects of irradiance variation, dust accumulation, shading, and tilt angle on the output characteristics of PV modules. Design / Methodology / Approach: The study employs a systematic evaluation of the effects of environmental factors on solar PV performance. A typical high-irradiance summer month (June) is selected to ensure that the experiments are conducted under realistic outdoor conditions. A single-axis solar tracking system is integrated to track the sun’s daily movement, and the output of the tracked system is compared with that of a static PV setup to quantify the performance improvement. The study focuses on four major environmental parameters—irradiance levels, dust accumulation using rice husk particles, shading patterns, and panel tilt angle variations. Further evaluation includes determining efficiency, power output, and performance ratio under varying conditions, enabling comparative analysis to identify the most critical factors affecting PV reliability and output. Research Limitation: The current experimentation and analysis are limited to controlled laboratory environments and a specific panel size for indoor and outdoor radiation levels. For indoor experimental results, an artificial radiation source has been connected. Findings: The experimental results in this paper show that the efficiency of solar PV power systems is significantly affected by environmental parameters such as temperature, irradiance, dust, shade, and colour spectrum. PV cell output was directly affected by irradiance, with higher levels resulting in greater power production and energy conversion. Practical Implication: The framework can be effectively used to determine schedules for panel maintenance and cleaning to ensure continuity of output. Also, specific tilt angles or tracking mechanisms can be decided. It can also be implemented for a single-axis or dual-axis setup, depending on the consumer's requirements. Social Implication: By enabling more energy-efficient processes, the work promotes sustainable practices and enhances the reliability of energy-dependent domains such as agriculture, small-scale industries, and remote areas where grid-based energy supply is difficult. Originality / Value: This work presents an original integration of an in-depth study of parameters such as radiation levels, particularly diffuse radiation, the significance of manual or automated tilt-angle adjustment, and the importance of solar panel maintenance, including regular cleaning schedules.
