In view of this situation, there are some portable photovoltaic modules in the market of portability, but with several major drawbacks: first, a part of the so-called portable photovoltaic modules actually reduces the power area of the modules, but the smaller the area of the modules, the lower the Conversion performance and worse is the feasibility. In addition, the modules are very heavy and the density of the existing crystalline silicon modules is over 10kg / m ² , so they are not suitable for carrying and transporting. Strictly speaking, this type of ratio-reduced crystal modules does not belong to the portable photovoltaic modules.
