The background color of the monocrystalline silicon surface is black or light blue, and that of the polycrystalline silicon surface is mostly blue or colorful. Compare monocrystalline and polycrystalline solar panels, the area of polycrystalline solar panels of the same power is slightly larger than that of monocrystalline solar panels.
Polycrystalline solar panels have good directivity because they receive light in multiple directions. If you block the sun’s rays by a hand and leave a shadow on the surface of solar panels, the reduction of the current generated by polycrystalline solar panels is smaller than that of monocrystalline solar panels. This is the advantage of polycrystalline solar panels, and the price is relatively low.
The electricity generated by the energy generation panel is a direct current with positive and negative poles. When charging, the positive and negative poles of the generation panel can be respectively connected to the positive and negative poles of the battery. There is a backflow prevention tube in the wiring box for monocrystalline and polycrystalline panels. When the battery is full, the charging of the battery will automatically stop. So, it has the function of preventing overcharging.
