The permanent loads include the weight of the structure, the integration system, the solar panels, the wiring, and the equipment. Cable-supported photovoltaic (PV) modules have been proposed to replace traditional beam-supported PV modules. The new system uses suspension cables to bear the loads of the PV modules and therefore has the characteristics of a long span,light weight,strong load capacity,and adaptability to complex. A thorough structural load analysis is not just a preliminary step; it is the foundation of a safe, durable, and effective solar energy system. This process ensures your roof can handle the added weight and environmental forces for decades, protecting both your home and your investment. Most significantly,solar panels wil increase the loadon your existin ra ing at a voltage of 400 V: I = 7300 / 400 = 18.
