Solar street light through three parts to understand the required data dynamic | | industry lighting: the rural solar led street lamp manufacturers
The same as the basic principle of solar photovoltaic power generation system, solar street lamp design train of thought is based on the general solar power generation system, make sure the power of the light source, a day of working hours, ensure a few rainy days and then calculate the capacity of the battery and the power of solar cell components.
But solar street light has its particularity, it is necessary to make sure the system work stable and reliable, so need special attention in the design of three parts of the data.
First, solar street lamp design need to know some data, can check it on the outdoor solar street lamp installation used to use the latitude and longitude.
China's different inclined surface solar radiation database)
To determine solar cell components of tilt Angle and azimuth Angle and calculating the area of solar standard peak sunshine time.
Second, the selected light source of led solar street light power (
The size of the light source power directly affects the stability of the whole system parameters.
Solar street light work time every night,
It is decided to system components in the size of the key parameters of the solar street lamps, by determining the number of working hours and can be a preliminary calculation load every day power consumption and the corresponding charging current of the solar battery components.
Third, the need to keep the continuous rainy days (solar street lamps
This parameter determines the size of the storage capacity and recovery after the rainy day solar cell components of power battery capacity needed.
Determine the interval between two consecutive rainy days D.
This is after the decision system in a continuous rainy day full of battery needed to power battery components.
