When users choose solar street lamps, they will choose solar street lamps with different power according to the width of street lamps and working time, continuous cloudy and rainy days. For solar street lamps, they mainly rely on solar panels, and the voltage of solar panels is generally 17.5V and 36V.
At present, the light source of solar street lamps on the market is specially designed for solar panels, so the conventional voltage is 12V/24V/ 36/this is the mainstream, of course, there are also higher, such as 48V/72V and so on.
The voltage of solar street lamps is mainly affected by the voltage of panels, batteries and light sources.
More important solar panels, solar street lamps, it has better voltage calculation, whether it is a single crystal, polycrystalline, whether how much of a cell, it is about 0.5 v voltage, different sizes of panels according to the different number of panels together, so that the solar street light are frequently used in the storage battery is 12 v and 24 v two specifications.
The second is the battery voltage, generally in the design, the voltage of the solar panel is 1.5 times the rated voltage of the battery. So understand the panel voltage, the rated voltage divided by 1.5, is the battery voltage. In the market, the common voltage specifications of batteries are 12V and 24V.
Then, the LED lamp holder is considered as the light source of solar street lamps, which generally cannot withstand high voltage. Therefore, it is designed for solar panels, and the voltage mainstream is also 12V / 24V / 36V.
