Fig. 15 illustrates the Bubble formation affecting the photovoltaic module. Bubbles frequently appear in the center of the cells, caused by the difference of adhesion due to high temperatures in the cell. The bubbles inhibit the heat dissipation of the cells, increase the superheating, reduce the service life of the module, decrease absorption
A review of previous literature implies that solar panels have an average degradation rate of at least 0.5% per year, although this rate will be higher in warmer climates. This means that under the best conditions, on average, after 20 years, the panel can produce less than 90% of the electricity produced in the first year.
Encapsulants like ethylene vinyl acetate (EVA) and polyolefin (POE) are used for solar modules to protect the cells from external factors (moisture and contaminants).
Air bubbles are introduced inside the cooling jacket, which generates turbulence motion and cools the PV panel. The cooling system is inspected while running at different panel temperatures.
