SOLAR PANEL

Solar panel, also known as "solar chips" or "photovoltaic cells", are thin slices of photovoltaic semiconductor that generate electricity directly from sunlight.

The photoelectric conversion efficiency of monocrystalline solar panels is about 15%, with the highest reaching 24%, which is the highest among all kinds of solar panels. However, the production cost is so high that it cannot be widely used.

The photoelectric conversion efficiency of polysilicon solar panels is much lower, which is about 12%. In terms of production cost, it  is cheaper than monocrystalline, material manufacturing is simple, save power consumption, the total production cost is lower, so it has been developed in large quantities.
