A hot spot occurs when a large number of solar cells are clustered together and a cell for a number of reasons such as: differences in cell build-up in the quality drop factory (eg, capillary cracking), shadow fall From buildings, vegetation surrounding, etc., falling leaves of trees on the panel, the effects of birds, darkening the color of the panel compartment, etc.) have a lower temperature. In this case, the total circuit current is limited to the “bad” or “faulty” cell flow. The ability to generate additional flow by “good” or “healthy” cells causes the direct bias of the “good” cells and because in the short circuit, the voltage of the two circuits is zero, the “bad” cell is reversed. Reverse The “bad” cells cause the cell to be removed from the manufacturer’s state and be converted into a consumer whose energy is consumed in heat. What consequences does the cell have in reversal? If the number of cells “Good” in the circuit is large, the magnitude of this inverse voltage in the two “bad” cells of the head is large and leads to a lot of energy losses, which are intense losses occurring at a small point. This leads to a hot spot in the panel called “hot spot heating”.
