For a street light that consumes 900WH, after calculation, the battery panel power required by the former =900*1.333/6.2=193.5 Wp, and the battery panel power required by the latter=900*1.333/4.6=260.8 Wp. From this we can conclude that the more sunlight there is, the smaller the solar panels you need and vice versa.
The total watt-hours is the electrical energy consumed by solar street lighting system every day, which directly affects the capacity of the battery and the power selection of the solar panel.
The higher the luminous efficiency, the better the energy-saving effect. It is also one of the most important indicators for choosing solar street light. However, this is not clearly specified in the LED standard, so it must be carefully confirmed when purchasing solar street light.
In addition, in the solar street lamp module, the line loss, controller loss, the power consumption of sensors, and constant current source are different, which may be about 5% – 25% in practical application. So 162w is only the theoretical value, which needs to be increased according to the actual situation
When designing the solar street lamp power system, we generally calculate the daily power generation, storage, and power storage according to the power consumption of the lamp, and finally provide a scientific and reasonable configuration scheme for the user. The factors that affect the power system. Width and lanes of the road
