Mitigating Strategies for Hot Spots in Crystalline Silicon Solar Panels

Hot spots are evident in this infrared picture showing elevated temperature where the cells are damaged along the frame

Hot spots are areas of elevated temperature affecting only part of the solar panel. They are the result of a localized decrease in efficiency, which results in lower power output and an acceleration of the materials degradation in the affected area. Solar panels generate significant power and hot spots can occur when some of that power is dissipated in a localized area. Hot spots are rarely stable and will usually intensify until total failure of the panel performance in terms of electricity production and/or safety.
