[0002] Solar energy refers to the thermal radiation energy of the sun, which is mainly manifested in the so-called sunlight. As a green, clean, pollution-free and inexhaustible energy source, solar energy is becoming more and more popular, and various solar power generation devices are emerging in an endless stream; solar power generation devices are mainly composed of solar cell modules, solar control boxes, and batteries; solar cell modules are the core part of solar power generation devices and the most valuable part of solar power generation systems. Their function is to convert solar energy into electrical energy, or send it to batteries for storage, or drive loads to work. When similar existing photovoltaic power generation and energy storage devices are in use, photovoltaic power generation and energy storage devices are prone to explosions or fires when colliding, and most of the current protective devices use a simple installed protective shell for protection. Due to the lack of buffering, the protective shell is easily damaged when it is hit by an external impact.
