6 FAQs about [What is the situation when hot spots appear on solar photovoltaic panels]
How does a hot spot affect a solar panel?
Hot spots result in increased resistance in affected cells, leading to power dissipation as heat. This energy loss reduced the overall power output of the panel, resulting in lower efficiency and decreased electricity generation. The higher the number and severity of hot spots, the greater the impact on the panel’s overall performance.
