To put it simply, the difference between single crystal silicon and polycrystalline silicon is their atomic structure arrangement. Single crystals are ordered, and polycrystals are disordered. This is mainly determined by their processing technology. Polycrystalline is mostly produced by casting. That is, the silicon material is directly poured into the pot to melt and set, and the single crystal is modified by Siemens method. The straight drawing process is a process of atomic structure reorganization. To our naked eyes, the surface of the single crystal silicon looks the same, and the surface of the polysilicon looks like there is a lot of broken glass in it, shining.
Monocrystalline solar panel: no pattern, dark blue, almost black after packaging, suitable for use in places with strong light.
Polycrystalline solar panel: there are patterns, there are polycrystalline colorful and polycrystalline less colorful, like snowflake crystal pattern on snowflake iron sheet, light blue, suitable for use in cold and snowy areas.
Inverter is the core equipment of photovoltaic system. Solar photovoltaic cells convert light energy to dc electricity, which is then converted through the inverter to 50 hz, 230/400 v three-phase or 230v single-phase ac.When using inverters in photovolta
Solar pv micro inverters technology is a kind of MLPE technology, it has been a hot market. According to the data, more than half of the roofs of most photovoltaic power plants use micro-inverters. 1. High safety (1) dc voltage is low In the tr
