Many people, like the low-priced products, the product quality on the second. But You get what you pay for. We are in the market research to understand, many people do not approve of solar electronic products, the main reason is that there are a lot of Cheap and inferior products in the market, lots of product quality problems. If product is not practical, short life. This has resulted in people's consumer sentiment has been dampened. Thus arises the mistaken belief that solar electronic products was just toys, and does not work.

Solar electronic products mainly to evaluate the following aspects:
1) Solar panel
At present the market is divided into amorphous silicon solar cells and crystal silicon. Which can be divided into poly-Si and silicon. From the three kinds of materials, photoelectric conversion efficiency of view is: Si "polycrystalline silicon" Si. But the crystalline silicon Basically, under the solar panel in low light there will be no current production, amorphous low-light is good. Therefore, in different occasions require different types of solar panels.
Next we want to focus is the power of solar panels, in general, solar panels with solar power is proportional to the size of the chip (the area of solar cell wafers are not fully comparable to a solar energy package Panel area, because some solar panels though large, but the solar energy chips arranged in a very wide gap, this is not necessarily a high-power solar panels. Although the appearance of solar panels for example, some small but tightly packed chips .In the relatively small area has also achieved relatively large power). In general, solar panel power is the bigger the better, so that the sun produces the current, can quickly be built-in battery is full. But in reality, the need to Solar panels to power and the portability of solar chargers to find a balance.
