Solar street lamp is a kind of lighting equipment that uses solar energy to generate electricity. It has the advantages of environmental protection, energy saving and no need of power grid, and is widely used in urban roads, rural roads, parks and other places. When purchasing solar street lamps, you need to consider the following aspects.

First, choose the appropriate power and brightness. The power and brightness of solar street lamps directly affect the lighting effect. Generally speaking, the greater the power and brightness, the wider the lighting range. Select the appropriate power and brightness according to the actual needs to ensure that the street lamp can meet the lighting requirements.

Secondly, we should choose efficient solar panels. Solar panels are the core components of solar street lamps, which are responsible for converting solar energy into electric energy. When purchasing, solar panels with high efficiency and high conversion efficiency should be selected to ensure that street lamps can be charged in sufficient sunlight and provide stable power supply.

Third, choose the right battery. Solar street lamps are usually equipped with storage batteries, which are used to store the electric energy obtained by charging during the day for use at night. When purchasing, you should choose a battery with appropriate capacity, long service life and high charging and discharging efficiency to ensure the continuous power supply and long service life of the street lamp.

In addition, it is necessary to choose appropriate controllers and lamps.
