• When you are ready to new purchase some solar products,why you choose the best solar panel

  Dec 08, 2022

  1. Monocrystalline silicon solar cell At present, the photoelectric conversion efficiency of monocrystalline silicon solar cells is about 15%, and the highest is 24%. This is the highest photoelectric conversion efficiency among all kinds of solar cells, but the production cost is so high that it cannot be widely and universally used.   Monocrystalline silicon is generally packaged with tempered glass and waterproof resin, so it is sturdy and durable, with a service life of 15 years in general and 25 years at most.   2. Polycrystalline silicon solar cellThe production process of polycrystalline silicon solar cells is similar to that of monocrystalline silicon solar cells, but the photoelectric conversion efficiency of polycrystalline silicon solar cells needs to be reduced a lot, and its photoelectric conversion efficiency is about 12% (on July 1, 2004, Sharp, Japan, listed the world's highest efficiency polycrystalline silicon solar cells with an efficiency of 14.8%).   How to distinguish between Monocrystalline Solar and Polycrystalline Solar? 1, Different Color.The typical monocrystalline panel will tend to have a darker black color, polycrystalline panels tend to have a blue color. 2, Silicon Shape. Monocrystalline panel silicon is not a regular square shape, but polycrystalline panel silicon is a regular square shape.     When you are ready to purchase some solar products, you may want to choose the best solar panel. So do you know what you can do? There are two types of solar panel material in the market, one is Monocrystalline, and the other one is Polycrystalline. Normally, we will suggest more to our customers to choose Monocrystalline Solar when they ask for solar street light, because Monocrystalline will be more efficient. It can collect more sun power convert to electronics.

• When do solar lights turn on,How do solar street lamps automatically illuminate at night

  Feb 13, 2023

  When do solar lighs turn on,How do solar street lamps automatically illuminate at night? Generally, the solar lamp will not light up in the daytime. The solar lamp is in an absorption state in the daytime. It will start to light up when the light is dark at night and meets the requirements of the solar lamp.   The solar panel of the solar street lamp absorbs solar energy, converts it into electric energy, stores it in the charging device, and releases it at night.   Many outdoor solar street lamps get a complete timer or photosensitive device to let them automatically emit light in the dark.     If the panel of the solar lamp is covered, such as the panel is covered by dust, or the panel is covered by snowflakes in snowy weather, then the solar lamp will not work normally, and the output voltage of the solar lamp will become low. At the set value, the solar lamp will glow in the daytime. LIGHT MODE - PIR Sensor 1. When the motion detected, the lamp will shift to 100% brightness automactically. 2. The lamp stay on with 30% brightless .when no motion LIGHT MODE - Time Control Total Time: 12h，100% Brightness，50% Brightness，30% Brightness，20% Brightness 1. The lamp will stay on according to above metioned hours and lighting percentage (12H). 2. It will shift and turn on/off automactically. Remark: Light mode and brightness can be customized. The solar lamp converts the absorbed solar energy into electric energy. When the light is strong, the output light will be lower. If the voltage of the solar lamp is lower than the set value, the street lamp will be turned on. If the voltage is higher than the set value, the street lamp will be turned off
