Differences Between Mono PV Panels and Poly PV Panels:
1. Different conversion efficiency
At present, the photoelectric conversion efficiency of monocrystalline silicon solar cells is about 17%, and the highest is 24%, which is the highest photoelectric conversion efficiency of all kinds of solar cells. The production process of polycrystalline silicon solar cells is similar to that of monocrystalline silicon solar cells, but the photoelectric conversion efficiency of polycrystalline silicon solar cells needs to be reduced a lot, and photoelectric conversion efficiency is about 15%.
2. Different manufacturing costs
The production cost of monocrystalline silicon is so high that it can not be widely used. In terms of production cost, it is cheaper than monocrystalline silicon solar cells. The materials are easy to manufacture, saving power consumption, and the total production cost is low, so it has been developed in large numbers.
3. Different service life
The service life of polycrystalline silicon solar cells is also shorter than that of monocrystalline silicon solar cells. Monocrystalline silicon is generally packaged with tempered glass and waterproof resin, so it is sturdy and durable, with a service life of 15 years in general and 25 years at most. In terms of performance price ratio, monocrystalline silicon solar cells are slightly better.
