The "Socrates Portable" is the world's first device that conducts crack detection in solar panels using the eddy current magnetic induction method. If cracks in solar panels are left unattended, there is a possibility that the cracks will spread from that point, allowing moisture to enter, which can eventually lead to patterns known as snail trails appearing on the surface, potentially reducing power generation efficiency. Additionally, if the electrode pattern is broken due to cracks, hot spots can occur, which may lead to fires. Traditionally, crack detection in solar panels required stopping power generation, removing the panels, or flowing a large current while the panels remained installed, capturing the luminescence phenomenon of the panels through photography. The determination of the presence of cracks was also done visually, requiring experience. This product allows for crack detection before installation, after installation (during operation), regardless of daytime or sunset. Moreover, there is no need to flow a large current, so it does not put a burden on the panels. Furthermore, since it is a battery-operated handheld type, it is easy to operate and enables quick crack detection in solar panels.
