Yangzhou Jinghua new energy tells you: the difference between single crystal solar panel and polycrystalline solar panel

2020-06-10

What's the difference between polycrystalline silicon and monocrystalline silicon? The difference between polycrystalline silicon and monocrystalline silicon: the background color of monocrystalline silicon is black or light blue, and the background color of polycrystalline silicon is mostly blue or color

What's the difference between polycrystalline silicon and monocrystalline silicon? The difference between polycrystalline silicon and monocrystalline silicon: the background color of monocrystalline silicon is black or light blue, and the background color of polycrystalline silicon is mostly blue or color.
Difference: compared with polycrystalline board, the area of polycrystalline board is slightly larger than that of monocrystalline board.
Advantages: the polycrystalline plate receives light in multiple directions with good directivity. In the actual test, if one hand is used to block the sun's light and leave a shadow on the surface of the solar panel, then the current reduction of the polycrystalline panel is smaller than that of the monocrystalline panel, which is the advantage of the polycrystalline panel. And his price is relatively low
Usage of power generation board
The electricity generated by the power generation board is direct current, with positive and negative poles. When charging, the positive and negative poles of the power generation board are respectively connected to the positive and negative poles of the battery. There is a backflow preventer in the junction box of polycrystalline and single crystal board. When the battery is full, the charging of the battery will stop automatically. It has anti overcharge function.
Factors to be considered in the design of solar power generation system: (please provide the general data to customer service)
1. Where is the solar power system used? How is the solar radiation in this area?
2. What is the load power of the system?
3. What is the output voltage of the system, DC or AC?
4. How many hours does the system need to work every day?
5. How many days of continuous power supply does the system need in rainy days without sunlight?
6. In the case of load, pure resistance, capacitance or inductance, what is the starting current?
7. Number of system requirements.
