Hotspots are localized temperature increases in solar panels that can seriously impact their performance. They occur when there's a problem with one of the connections between photovoltaic cells, causing increased resistance and a rise in potential difference. It's often due to uneven electricity flow caused by a malfunctioning or shaded cell. As a result, the panel gets heated and overloaded, which leads to a short-circuit that lowers output efficiency overall while hastening material deterioration. This effect can impact both the panels and the solar generation system as a whole.
