Problems solved by technology

This large-scale solar photovoltaic cell module is suitable for large-scale grid-connected power stations, but it is not suitable for a single user because of its large footprint, non-movability, and high consumption of auxiliary materials.
The other type is small solar cells, whose output power is about 2W, which is suitable for charging low-power products and is easy to move. However, due to the small power of this small solar cell, it cannot meet the power supply requirements of high-power electrical appliances.

Description

technical field [0001] The invention relates to the technical field of solar photovoltaic power generation, in particular to a solar photovoltaic power generation device. Background technique [0002] As we all know, solar energy is a renewable and clean energy, which makes solar photovoltaic power generation play an increasingly important role in power supply. Specifically, the solar photovoltaic power generation refers to converting solar radiation energy into electrical energy through the photovoltaic effect. Wherein, the photovoltaic effect refers to the use of solar cells to absorb light energy in the presence of light (the light can be sunlight or light generated by other illuminants), so that the two ends of the solar cells appear different The accumulation of the number of charges, thereby generating a photo-generated voltage, converts light energy into electrical energy. [0003] The most basic component of solar photovoltaic power generation is solar cells, mainl...
