FOLDABLE PHOTOVOLTAIC MODULE
Technical Field
The disclosure relates to a photovoltaic module, which belongs to the technical field of power generation, transformation or distribution.
Background
Building Integrated PV (BIPV) means that photovoltaic modules are both functional materials, i.e., materials for power generation, and building elements. Compared with Building Applied PV (BAPV), BIPV has many advantages in terms of cost and other aspects. For most parts of China, the development of BIPV is the most likely way to make the levelised costs of photovolt ic power generation equal to or even lower than the cost of fossil energy power generation. However, the current BIPV application in China accounts for only about 3% of the total installed capacity of photovoltaic power generation. A large number of roof resources are idle, and there is a great development potential.
Photovoltaic tile is a structure in whic;h photovoltaic modules- are embedded in a supporting structure , so that solar panels and building materials are integrated into one. Photovoltaic tiles can be directly applied to the roof, and installed on the roof structure like ordinary roof tiles. However, when traditional photovoltaic modules and their improved modules are applied for BIPV, many problems, such as high quality, disability of applying to curved surfaces, inconvenient transportation, insufficient flexibility, and high costs in structural reinforcement, installation and maintenance, may be en countered.
