[0002] A crystalline solar cell panel is a device that converts solar energy into electrical energy using the photovoltaic effect. A crystalline solar cell panel, also known as a photovoltaic solar cell panel, is usually composed of multiple photovoltaic cells. These photovoltaic cells absorb sunlight and convert it into direct current electrical energy. These panels can be installed on the roofs, ground, or other suitable areas of buildings for power generation or power supply. As an important means of clean energy power generation, photovoltaic solar cell panels are attracting more and more attention and are widely used.
