Hello
5V means that when the sun is sufficient, the electricity generated by this solar panel is 5V. The power of this panel is 5W. Under normal circumstances, it is composed of ten small batteries. The original card sheet is soldered. The standard battery sheet voltage is 0.5V, and the desired voltage is an integer multiple of 0.5. This battery board can charge cell phone battery.
What type of solar panel is used for a 5V lamp?
If it is a crystalline silicon solar cell, each cell is approximately 0.5V and many small cells can be connected. series, so we can't be sure of its surface area.
Amorphous silicon is about 1 cm/section, so for an operating voltage of 5 V, the length of the side in the direction of the voltage must be 11 cm.
Amorphous silicon solar panels. 5V lamps use panamorphous silicon solar cells. The market outlook for amorphous silicon solar cells is promising, the technology is becoming more and more mature, and the efficiency and stability of photoelectric conversion are constantly improving. Amorphous silicon cells are typically formed by decomposition and deposition of gases such as high purity silane using the PECVD (Plasma Enhanced Chemical Vapor Deposition) method.
