How to choose an integrated solar light?
Nowadays, integrated solar street lamps are more and more popular because of their compact structure, convenient installation and convenient use. All kinds of styles, various configurations, complex and confusing people¡¯s eyes. How on earth should choose suitable for their own use and genuine integrated solar street lamp? What problems should be paid attention to in the purchase?
First make sure to determine the following factors when purchasing:
First of all, it is necessary to check whether the installation location is well lit and whether the sunlight exposure time is sufficient. Without sunlight, no electricity can be generated, and the shading environment also seriously affects the working efficiency of the solar energy system and cannot install solar lamps.
The second is to observe the installation position, fixed on the wall or on the lamp pole, which determines the structure of the integrated solar lamp, fixed on the wall to choose the flange structure, lamp pole to use hoop structure.
According to the required area of illumination to determine the power of solar lamp, because the current solar street lamps are led light source, many people do not understand its brightness, but you can probably understand that a watt of LED is far greater than ten watt of fluorescent lamp, is twice the brightness of energy-saving lamp.
According to the lighting power of solar lamp to determine the size of solar panel and solar battery. The calculation is complicated, but the calculation configuration can be required by the manufacturer, and the general high school graduates can also perform the calculation.
According to the above requirements for selecting solar lights, we should pay attention to the following points when purchasing:
The first is the actual working efficiency of the solar lamp. The power of the solar lamp is different from the actual working power. The 100W lamp can be adjusted to one watt or even lower. This is especially important.
The second is to pay attention to the actual capacity of solar panels and batteries. For example, the 12V system of solar panels is twice as efficient as the 6V system. When battery 12 (actually 11.1) volts is 10 amps, it is equivalent to 30 amps of 3.7-volt system.
The third is to choose the general problem that solar street lights should pay attention to.
