1. appearance difference from the appearance of the above, the four corners of the single crystal cell board are arc-shaped, and there is no pattern on the surface. Monocrystalline panels all look the same on the surface. The four corners of the polycrystalline panel show square corners, with patterns, polycrystalline colorful and polycrystalline less colorful, like snowflake crystal patterns on snowflake iron sheets, in light blue.
1. appearance difference
From the appearance of the above, the four corners of the single crystal panel are arc-shaped, and the surface has no pattern. Monocrystalline panels all look the same on the surface. The four corners of the polycrystalline panel show square corners, with patterns, polycrystalline colorful and polycrystalline less colorful, like snowflake crystal patterns on snowflake iron sheets, in light blue. The surface of the polycrystalline panel looks like there is a lot of broken glass in it, shining.
2. manufacturing process difference
The difference between monocrystalline silicon and polycrystalline silicon lies in their atomic structure arrangement. Single crystal is ordered and polycrystalline is disordered, which is mainly determined by their processing technology. Polycrystalline is mostly produced by casting method, that is, silicon material is directly poured into a crucible for melting and shaping, while single crystal is modified by Siemens method. Czochralski process is a process of atomic structure reorganization.
The energy consumed in the manufacturing process of polycrystalline solar panels is about 30% less than that of monocrystalline solar panels. Therefore, polycrystalline solar panels account for a large share of the total output of global solar panels, and the manufacturing cost is also less than that of monocrystalline solar panels.
Power inverter is the key electronic component of solar power generation system. In commercial applications, these components connect photovoltaic (PV) panels, batteries that store electrical energy, and a local power distribution system or utility grid.
The design of solar panel capacity is very important, and the capacity size Z finally reflects how much solar energy resources can be used. Solar panel capacity design is very simple, solar panel capacity mainly refers to the storage energy of solar panels.
