I-V Curve testing and Insulation Resistance testing are both vital procedures that help ensure the performance and safety of solar installations. The I-V curve is a graphical representation of a solar module's electrical characteristics. It shows the relationship between the current (I) and voltage (V) that the solar module produces under different conditions. The shape of the I-V curve can tell us a lot about the solar module's performance and efficiency, allowing technicians to identify issues...
