The degradation of a PV (photovoltaic) module is the term used to describe the steady decline in efficiency and output power of a solar panel over time as a result of numerous environmental influences, manufacturing flaws, and material degradation.
As photovoltaic penetration of the power grid increases, accurate predictions of return on investment require accurate prediction of decreased power output over time. Degradation rates must be known in order to predict power delivery. This article reviews degradation rates of flat-plate terrestrial modules and throughout the last 40years.
Utilizing solar PV to generate energy is not a simple operation due to degradation, which can result in a reduction in solar PV performance and efficiency [1, 2]. According to recent studies, the rate of degradation varies between 0.6% and 0.7% per year [3, 4].
The National Renewable Energy Laboratory mentions that the degradation rate is around 0.5% to 0.8 % per year but varies depending on the model, brands, and types of panels. 1. Degradation Due to Light Induction: This occurrence affects solar panels, in which efficiency is reduced temporarily at the primary exposure of sunlight.
Photovoltaic cells degradation is the progressive deterioration of its physical characteristics, which is reflected in an output power decrease over the years. Consequently, the photovoltaic module continues to convert solar energy into electrical energy although with reduced efficiency ceasing to operate in its optimum conditions.
Therefore, the accuracy of this fitting model was proven as it portrays, simultaneously, the behavior of photovoltaic cells in the absence and presence of degradation. The crystalline silicon cell is a rigid structure, and the remaining studied technologies are flexible.
