Among many solar products, monocrystalline silicon and Polycrystalline Solar Panel, as two main technical routes, have attracted widespread attention. They are very different in terms of efficiency, cost, etc.
We first extract extremely pure silicon from quartz sand as the basic material for producing monocrystalline silicon panels, and then use the Czochralski method to grow molten silicon into monocrystalline silicon ingots under controlled conditions. Finally, we cut the monocrystalline silicon ingots into thin slices, paying attention to keeping the crystal structure intact, and the uniformity and integrity of the slices.
Monocrystalline silicon solar panels have a complete crystal structure, so their photoelectric conversion efficiency is very good. However, its production cost is relatively high. It can produce a lot of electricity per unit area and has a high return on investment. Moreover, its material is very good and its environmental adaptability is strong. We can use it for up to 25 years.
Monocrystalline silicon solar panels are more suitable for places with limited space but high energy efficiency requirements, such as rooftop photovoltaic systems, commercial buildings, etc. Its output is very efficient, and we can get the maximum power output.
The production process of Polycrystalline Solar Panel is simpler. First, the silicon material with lower purity is melted, and then the molten silicon is poured into a pre-prepared mold and cooled to form a polycrystalline silicon ingot. We cut the polycrystalline silicon ingot into thin slices, which will be further processed into solar cells. This process is more cost-effective than the production process of monocrystalline silicon. The production process of polycrystalline silicon solar panels is relatively simple, and the cost of raw materials is relatively low, so it is more efficient than monocrystalline silicon. We can use Polycrystalline Solar Panel in many places, and its environmental adaptability is also good and relatively stable.
We can use Polycrystalline Solar Panel in some large photovoltaic power stations. Its cost and efficiency are very good. If our budget is limited, we can also choose Polycrystalline Solar Panel. So when we choose solar panels, we should pay attention to its characteristics and choose suitable crystalline silicon solar panels.
