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.
The methodology to research the degradation of PV module. The average degradation rates are found to be 1.24%/year for a-Si, 0.14%/year for HIT, and 1.50%/year for mc-Si. Embrittlement of PA and PET backsheet results from prolonged UV exposure, temperature cycles, and humidity, causing cracks in the UV layer and degradation. Table 1.
However, most ROI estimation neglects the decline in efficiency of power generation over time (degradation rate). As use of solar power grows, accurate prediction of PV module efficiency is important.
The data indicate that, after 12 years of operation, the degradation rate ranges from 1.32% to 1.62%. Additionally, to analyze the causes of this degradation, the EL imaging results of two polycrystalline PV panels after 12 years of operation reveal that the primary degradation is due to disconnections between cells. Table 7.
Locally measured meteorological data from National Weather Service (NWS): solar irradiance, air temperature, humidity, precipitation and the UV index, were considered as independent variables to see if meteorological parameters are related to degradation rate and which variables highly trigger the degradation of solar PV modules.
The long-term performance of photovoltaic (PV) modules declines over time, influenced by environmental conditions such as temperature, humidity, and shading, which pose operational challenges. Quantifying this long-term degradation is crucial for predicting the return on investment of PV systems.
