Solar cell
Solar cells are an electronic product, which is mainly divided into crystalline silicon (including monocrystalline cells and polycrystalline cells) and amorphous silicon.
Among crystalline silicon cells, monocrystalline silicon has higher efficiency but higher manufacturing costs than polycrystalline silicon. The polycrystalline silicon plate is mottled blue, and the monocrystalline silicon plate is black.
Choosing which type to use requires consideration of regional climatic conditions. For example, monocrystalline silicon power generation efficiency is higher in rainy areas, while polysilicon may be selected based on cost and increase investment area in rainy areas.
