How many volts is the solar street light

What is the voltage of solar street light? There are three commonly used 12V, 24V, 3.2V one, 12V system voltage This is a common solar street light system voltage, and it is also the most used one. At present, most solar street light manufacturers on the market use this type of system voltage. The solar street light of this system voltage has two controller matching solutions, one is a buck controller with 3 series and 10 parallels, and the other is a boost solar street light controller with 10 series and 3 parallels. The 12V system voltage solar street light has medium price, excellent quality, long service life and high cost performance. 2. 24V system voltage 24V system voltage solar street light has two solar panels and two solar batteries, and the two solar panels are connected in series, and the two solar batteries are also connected in series, so that the overall system voltage is 24V. This type of system voltage has extremely high stability, but the solar street light with 24V system voltage is very expensive, which is half the price of the solar street light with the same 12V system voltage. Therefore, the solar street light with this system voltage is used. Not many. 3. 3.2V system voltage This type of voltage is used by many businesses in lithium battery solar street light systems in 2018. The method of 3.2V voltage is to connect all the solar cells in series. The advantage of solar street light with 3.2v system voltage is that the price of a full set of solar street light is very cheap, but the disadvantage is that the service life is short, the lighting effect is not very good and unstable, and the solar lithium battery needs to be replaced in less than two years.
