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, they can spread from the initial point, allowing moisture to enter and eventually causing patterns known as snail trails to appear on the surface, which can lead to a decrease in power generation efficiency. Additionally, if the electrode pattern is broken due to cracks, hot spots can develop, potentially causing fires. Traditionally, crack detection in solar panels required stopping power generation and either removing the panels or flowing large currents while the panels remained installed, capturing the luminescence phenomenon through photography. Determining the presence of cracks was also done visually, requiring experience. This product allows for crack detection before and after installation, during operation, and regardless of whether it is day or night. Furthermore, it does not require flowing large currents, thus not putting a burden on the panels. Additionally, being a battery-operated handheld type makes it easy to operate, enabling quick crack detection in solar panels.
