What are the solar panels of a portable power station?

Portable power station is composed of three parts: solar panels, special storage batteries and standard accessories. The first two are the key to the quality and performance of the product of the power supply, and should be considered in the selection process.

Solar panels

There are three types of solar panels on the market, including monocrystalline silicon solar panels, polycrystalline silicon solar panels and amorphous silicon solar panels.

Monocrystalline silicon solar cells are the more commonly used semiconductor cells for the production of solar power. Its production process has been finalized, and its stability and photoelectric conversion rate are high.
However, because the cost is too expensive, the monocrystalline silicon solar cells on the market, the conversion rate are between 15%-18%.

Polycrystalline silicon solar cells are less expensive than monocrystalline solar cells, better light sensitivity, in the sun and incandescent light can be sensitive to light. But the photoelectric conversion rate is only 11%-13%. With the development of technology, the efficiency is also improving, however, compared to the efficiency of monocrystalline silicon is still slightly inferior.

Amorphous silicon solar cell conversion rate is the lowest, the international advanced level is only about 10%, and is not stable, there is often a sudden drop in conversion rate phenomenon. Therefore, amorphous silicon solar cells are mostly used for weak light sources, such as solar-powered electronic calculators, electronic clocks and other aspects. Although the price is low, the cost performance is not high.

Overall, the choice of portable solar power, or to monocrystalline silicon and polycrystalline silicon, it is best not to be greedy for cheap and choose amorphous silicon.
