Teach you How to Choose a Portable Solar Power Station and Portable Solar Panel

LiFePO4 Power Station

For friends who like outdoor travel and wild adventures, portable solar power and portable solar panels should be indispensable equipment, because it can play for your camping LED lights, mobile phones, digital cameras, pSp, GpS, mp4 Digimon such as gadgets and notebook computers provide reliable green power guarantee. However, many portable solar power supplies and portable solar panels are currently in the preliminary stage of development, and the quality of products on the market is also uneven. Here is a brief introduction to how to choose portable solar power supplies and portable solar panels to provide you with a useful reference for choosing such products.

Convenient portable solar panel selection
Solar Panels Currently, there are three types of solar panels on the market: monocrystalline silicon, polycrystalline silicon, and amorphous silicon. Below, we will introduce these three solar panels from the perspective of consumer use:

Monocrystalline solar panel
The current production process has been finalized. It is a semiconductor battery that is more commonly used in the production of solar power. Its characteristics are: good stability and high photoelectric conversion rate. According to the current level of solar technology development, the photoelectric conversion rate of monocrystalline silicon solar cells can reach 18 %--23%, is currently the solar panel with the highest conversion rate.

Polycrystalline silicon solar panel
Compared with monocrystalline solar cells, the advantage lies in their low cost and better photosensitivity than monocrystalline silicon. They can be light-sensitive in sunlight and incandescent lamps, but the shortcomings are obvious. The photoelectric conversion rate is only 15%-18%. Development and efficiency are improving, but the efficiency is still slightly inferior to that of monocrystalline silicon.

Amorphous silicon solar panel
The problem of amorphous silicon solar cells is that the photoelectric conversion efficiency is low, 10%-15% and not stable enough, and the conversion efficiency is often declining. Therefore, it has not been widely used as large-scale solar power sources, and most of them are used for low light. Power supply, such as pocket electronic calculators, electronic clocks and so on. It is estimated that after the problem of efficiency decline is overcome, amorphous silicon solar cells will promote the development of solar energy utilization. At least the current cost-effectiveness of portable solar panels is still relatively low. A little bit, cheap, but not practical! !

Therefore, in general, the portable solar panels are mainly monocrystalline silicon and polycrystalline silicon, but there are also some merchants who are pursuing low prices one-sidedly without considering consumers' use of functions and using amorphous silicon solar panels. Please confirm the brand before purchasing and then purchase.

Portable solar power selection
Generally speaking, the main factors affecting the quality and performance of portable solar power products are: batteries used in portable solar power sources.

Because lithium batteries are very unsafe, there have been endless incidents of lithium battery explosions in recent years, so many suppliers have changed lithium battery packs to LiFePO4 battery packs to make portable solar power supplies, also known as LiFePO4 battery packs. LiFePO4 power station. Because of its higher safety performance, why is it said that its safety is higher than that of lithium batteries? For details, please see What is The Difference Between a Lithium Battery and a LiFePO4 Battery? This article.

In addition: Qualified portable solar power batteries will have overcharge, overcharge, overvoltage and overcurrent protection functions. After the battery is fully charged, it will automatically turn off and no longer be charged. When discharged to a certain extent, it will automatically cut off the power to protect the battery and power consumption. equipment.
