3. Tackling Solar Module Hotspots: The Core Problem
Hotspots in solar panels are a big issue. They make your system less efficient and can even damage it. These hotspots are warmer spots on the panel compared to the rest.
Why Hotspots Form on Your Solar Panels
Hotspots can be caused by many things. This includes defects in making the panel, shading, or damage. When part of the panel is shaded, it can get hotter than the rest.
The Impact of Elevated Temperatures on Photovoltaic Efficiency
High temperatures hurt your solar panels’ performance. They can make the material inside the panel break down. Studies say each degree above the usual test conditions can lower efficiency by up to 0.5%.
Traditional Cooling Methods and Their Limitations
Old ways to cool panels, like air or water, are used. But they have big downsides. They use a lot of energy and need a lot of upkeep.
