Types of Faults Detected with Our in-house tool

• Cell Fault: It occurs when the panel cell overheats. This can be seen in the thermal image as a point where the temperature is higher than the rest of the panel.
• Multiple Cell Fault: This is what happens when more than one cell in the panel overheats. It is indicated by several spots in the thermal image where the temperature has a higher intensity than the rest of the panel.
• Diode Fault: A Diode Fault provides a current path within a faulty cell or panel. The diode anomaly usually occurs in approximately 1/3 of the panel.
• Multiple Diode Fault: A multiple diode fault is a failure in a solar panel where more than one active bypass diode is affected. This fault usually occurs in about 3/2 of the panel.
• Hotspot Fault: It refers to an abnormal spot in one of the cells in a solar panel. This abnormal spot occurs in a high-resistance region of the cell, and the high resistance in this region causes the energy generated by other cells in the solar panel to accumulate at this point. As a result of this accumulation, overheating occurs in the cell and this point, called a hot-spot, has a higher temperature value than other cells.
• Junction Box Fault: The junction box is an enclosure that connects the arrays in solar panels and a failure of this box can affect the overall performance of the panel. It usually occurs when the junction box is not adequately insulated.
• Module Fault: It is a malfunction of the entire module in the solar panel, either a malfunction that causes the module to overheat or a malfunction that occurs as a result of the module being completely offline.
• Shadowing Fault: It refers to the reduction of production as a result of heating caused by shading on a certain area of the solar panel. Shading on the solar panel is usually caused by trees, buildings or other objects.
• Broken/Crack Fault: It is a heating fault caused by cracks on the surface of the solar panel due to environmental conditions. These cracks reduce the performance of the panel.
• Contamination Fault: A heating fault caused by dirt, dust or other debris accumulated on the surface of the solar panel.
• Plant Shading Fault: Modules are blocked by vegetation. Shade caused by the growth of plants in the immediate vicinity of solar panels creates heating in the panel and prevents production.
