This disclosure relates to, but is not limited to, the technical field of solar power generation, particularly relates to, but is not limited to, a portable reel-type solar power generation device and a reel-type solar power generation device.
Today's society is mainly dependent on traditional fossil energy sources. 74% of the world's total energy consumption comes from mineral energy sources such as coal, oil and natural gas. The application of fossil energy source has promoted the development of society, but the resources are increasingly exhausted. The uncontrolled use of fossil energy source has caused serious environmental pollution and climate change problems. Countries all over the world deem the development of renewable energy sources and new energy sources as an important part of their future energy strategy, and solar energy is one of the important development goals.
As a result of the rapid development of solar cells, especially flexible solar cells such as thin film solar cells, there is a prospect that these problems can be solved. At present, corresponding products have emerged in the market, such as solar charging paper, solar charging pack, etc. However, such charging equipment can only meet the short-term requirement of power. The solar power generated is unstable and thus cannot meet the power supply needed by large-sized or medium-sized electrical appliances.
With the emergence of flexible solar cell panels, many portable solar charging devices have been invented, but these portable solar charging devices still have many shortcomings, such as the area of available solar cell panels is too small, or the solar charging devices are not easy to carry with. For example, a common cell pack structure includes two substrates which are hinged with each other. The substrate is provided with a solar cell on which an upper cover is arranged. The cell pack can be folded around. However, the cell pack substrate is made of hard material and can only be folded simply. After being folded, the area thereof is still very large. Moreover, the thickness of the cell pack is also very thick, which makes the cell pack not easy to carry with. The cell assembly power that can be stored is not high enough.
