The solar panel is the core part of the solar power system kit and the most important part of the off-grid or grid-tie solar power system for house.
There are two types of solar panels: monocrystalline solar panels and polycrystalline solar panels. The photoelectric conversion efficiency of monocrystalline silicon solar panels is about 15%, and the highest is 24%, which is the highest photoelectric conversion efficiency of all types of solar panels. The photoelectric conversion efficiency of polycrystalline silicon solar panels is about 12%. In terms of production cost, it is cheaper than monocrystalline silicon solar panels. The material is easy to manufacture, saves power consumption, and has a lower total production cost. Therefore, it has been a lot of development.
