Is the voltage of the solar street light system 3.2V or 12V?

As a new energy technology product, solar street lights are gradually being widely used in rural areas. They absorb sunlight to generate electricity through the volt effect, clean and pollution-free, and are deeply loved by people. However, there are many types of solar street lamps on the market. There are three types of solar street lamp system voltages: .V, V, and V. Many purchasers are faced with these three system voltages but do not know how to choose. Today, solar street lamp manufacturers have made a comparative analysis of common .V and V system voltages, and let everyone see which one is better.


1. .V solar street lamp system voltage
Advantages: .V solar street lights are cheap, and household small solar lights use this system voltage to be more economical.
Disadvantages: low brightness, low efficiency, high requirements for the wire body and LED lamp beads, because the power of the solar street lamp is at least W, it will cause excessive current, rapid damage to the light source, and unstable system, which often leads to use for about two years It is necessary to replace the lithium battery and light source.
Two, V solar street lamp system voltage
Advantages: high brightness, work efficiency is about percent higher than the .V system voltage, the system is stable, and the overall service life is longer.
Disadvantages: Of course, the price is higher than that of .V solar street lights.


In summary, it seems that V solar street lamp system voltage is better. But everything is not absolute. We have to consider the actual needs and application scenarios of the purchaser. For example, household solar lights do not require too much brightness, and often use low-power light sources. Considering economy and practicality, at this time.V solar lights The system voltage is more cost-effective. If it is installed on rural roads, the power of solar street lights is often greater than W, so using V solar street light system voltage is obviously a more reasonable choice.
