About How are hot spots on photovoltaic panels formed

About How are hot spots on photovoltaic panels formed

In a photovoltaic (PV) module, a hot spot describes an over proportional heating of a single solar cell or a cell part compared to the surrounding cells. It is a typical degradation mode in PV modules.

Hot spots can origin, if one , or just a part of it, produces lesscompared to the other cells connected in . This may occur due to partially shading, dirt on the module (leaf, bird drop) or cell.

Quick detection is possible with infrared camera, performing . A hot spot can also lead to browning in the glass plane of the PV module, if it is present for long time. Thus, the hot spot can become visible for the human eye.To prevent emergence.Hotspots typically occur when a solar panel is shaded, preventing the current from flowing properly around weaker cells.
