Degradation of PV modules is highly dependent on the climate (Mussard and Amara, 2018) but also depends on lamination materials, solar module processing, aggressive environmental parameters, PV technology, period of exposition, the installation method, solar tracking system, solar radiation concentration mechanism and PV system voltage.
Both PV systems exhibited a degradation rate of 1%/year, which is likely attributed to aging effect. Jordan and Kurtz from the last 40 years of field testing study reviewed the degradation rates of different technologies PV modules and found a yearly average power degradation of 0.8%.
This review paper aims to evaluate the impact of defects on the reliability and degradation of photovoltaic (PV) modules during outdoor exposure. A comprehensive analysis of existing literature was conducted to identify the primary causes of degradation and failure modes in PV modules, with a particular focus on the effect of defects.
This study comprehensively examines the effects and difficulties associated with aging and degradation in solar PV applications. In light of this, this article examines and analyzes many aging factors, including temperature, humidity, dust, discoloration, cracks, and delamination.
The degradation of photovoltaic (PV) systems is one of the key factors to address in order to reduce the cost of the electricity produced by increasing the operational lifetime of PV systems. To reduce the degradation, it is imperative to know the degradation and failure phenomena.
Furthermore, power degradation occurred as a result of several failures that directly impacted and reduced shunt resistance, including soldering defects, microcracks, shading, and hotspots [230, 231]. Most of these failures were found to directly impact and increase series resistance, too [226, 232, 233].

The mean peak power degradation has been 30,9% in the 22 operation years, equivalent to 1,4% per year, which corresponds mainly to a loss in short-circuit current and, in a less degree, to loss in fill factor and open circuit voltage. The most significant defects found were severe browning, milky pattern and oxidation of the metallization grid ...

Solar eclipses temporarily reduce solar irradiance, causing a rapid but short-lived fall in solar power generation. A partial solar eclipse occurred in Prague on 20 March 2015 saw 68 % of the solar disc covered at its peak and caused a 69 % reduction in solar PV production [ 232 ].
The key characteristics of the incident solar irradiance on PV modules are its power, the spectral distribution and the angle of incidence. The global standard (AM 1.5G) solar spectral irradiance [60] covers the wavelength range of 280–4000 nm and corresponds to an integrated solar power of 1000 W/m 2. Although the UV region (280–400 nm ...
