3 -Separation between cells and panel frame:
This is, among other things, to reduce also the losses caused by the accumulation of dirt. In addition to this, SolarWorld photovoltaic panels, with this separation andtechnology applied in manufacturing, are free of PID effect. Its translation is Induced Potential Degradation.
This negative effect happens when connecting long strings of panels, then conduction can occur between the cells of the panel edges and the panel frame, so the performance of the panel is reduced dramatically. It is important to emphasize the PID effect and that a great majority of manufacturers that certify to be free of PID, is not reliable, as evidenced in the PID test carried out by the German laboratory Fraunhofer, where tested several brands of recognized prestige and only one handful of them passed the test successfully, many of them resulted in a “junk panel” we could call.
Only those panels that are subject to the continuous control of their production, as in the case of SolarWorld, can give us the peace of mind that all the panels that we are going to install will be free of the PID effect.
