What are the voltages of the solar street light system?

Solar street lights are a new type of energy-saving and environmentally friendly road lighting products. Because solar energy does not need to consume electricity, it has a great advantage and is vigorously promoted by the country in the construction of new rural areas. After several years of promotion and development, solar street lights have been used in most rural areas. Many people know their product parameters, but they don't know much about their system voltage. Today, the technicians of solar street light manufacturers will introduce to you which types of solar street light system voltages.

1. .V system voltage

This type of voltage is used by many businesses in lithium battery solar street light systems. The method of .V voltage is to connect all solar battery cells in series. The advantage of solar street lights with .v system voltage is that the price of a complete set of solar street lights 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 after less than two years of use.

2. V system voltage

This type of voltage is a common type of solar street lamp system voltage, and it is also the most used one. At present, most solar street lamp manufacturers on the market use this type of system voltage. This system voltage solar street lamp has two kinds of controller matching schemes, one is a series-parallel step-down controller, and the other is a series-parallel step-up solar street lamp controller. V system voltage solar street lights are medium in price, excellent in quality, long in service life, and very cost-effective.

3. V system voltage

V system voltage solar street lamp 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 V. This type of system The voltage has extremely high stability, but the price of solar street lights with the existing V system voltage is very expensive, which is half more expensive than the solar street lights with the same V system voltage. Therefore, the number of solar street lights using this system voltage is not large.

The above are the three system voltages of solar street lights. Solar street lamp manufacturers suggest that you still use the moderately V system voltage solar street lamp. The solar street lamp with this system voltage is the most cost-effective among the three types. The stability and price are all tested by the market. In addition, the .V system voltage solar street lamp can be used as far as possible without using it, because its service life is not long and the stability is not high, and the later maintenance is more troublesome than others.
