The increasing demand for TOPCon bifacial solar modules raised concerns among industry professionals about their potential for unsafe installation, particularly on sheet metal roofs. TOPCon bifacial modules, which are primarily manufactured in glass-to-glass format, are not ideally suited for installation above sheet roofs due to their structural and performance requirements. These modules are designed to capture sunlight from both sides, offering higher system efficiency. However, installing them on opaque, unventilated sheet roofs blocks rear-side exposure to light and traps heat. This limits power generation and significantly increases the risk of overheating and, in extreme cases, fire.
