Where can you find snail trails? Snail trails are a phenomenon of wafer-based silicon solar modules and represent a discoloration of the silver-containing front side metallization (metal mesh, cell…
Where do burn marks develop? Burn marks can appear on the entire surface of solar modules for a various number of reasons. Crystalline phovoltaic modules consist of solar cells that are connected to…
What delaminates on modules? Solar modules consist of interconnected solar cells or a semiconductor layer that are laminated under pressure and heat in an encapsulating material between a front glass…
Where do hotspots occur? Crystalline, wafer-based silicon solar modules consist of wafer-thin silicon solar cells that are soldered together in series to form strings during production. As a result…
