Maximizing Output: An Overview of Loss Analysis in Grid-Connected Solar Photovoltaic Systems

Abstract

The use of solar energy is growing in importance globally, but particularly in India. Since there aren't many
solar plants operating in India right now, there isn't any historical data. It is crucial to investigate how well
solar power plants operate. Acquiring knowledge about solar power plant performance will lead to wise
investment choices. In this work, we address the different aspects that affect solar power plant performance,
including age-related deterioration, inverter efficiency, design, temperature, and other environmental
circumstances. This study presents a performance parameter review of a grid-connected photovoltaic
system. Examined include the performance ratio and the numerous power losses (such as those caused by
solar radiation, various types of module losses, temperature, soiling of modules, AC and DC losses, cable,
and wiring loss, etc.). Additionally, the plant's performance was evaluated with respect to various plant
operating losses, such as generation loss resulting from grid unavailability and inverter malfunctions.
