       With the development of the times, today"s integrated solar street light china have adopted the new energy source of solar energy.Solar power as traffic road condition lighting for external power supply for street lamps. It plays a very important role in our urban life. It is our eyes of travel and nightlife.In some areas there will be a long rainy season, then some people may ask, can integrated solar street light china work on rainy days?

         Before we can figure out this problem, we need to understand how integrated solar street light china work. The integrated solar street light china converts the solar energy into electric energy to realize the illumination.During the day, these photovoltaic components convert the solar energy into electric energy and store it in the storage battery, so that the integrated solar street light china is under the control of the intelligent controller, and the solar panel is irradiated by sunlight to absorb the solar light. And converted into electrical energy, the solar cell assembly charges the battery pack during the day.In the evening, power is supplied to the light source through the control of the controller to illuminate people at night.

         At night, the battery pack provides power to supply power to the LED light source to achieve lighting functions. The integrated solar street light china are recurring in this way, charging during the day and discharging at night, and continuously cycling.That is to say, solar panels provide energy supply to integrated solar street light china.In the process, if there is no sunlight or insufficient sunlight, can integrated solar street light china work normally? This is to say that the important part of the integrated solar street light china - the working principle of the photovoltaic module: the sun shines on the semiconductor (usually silicon) PN junction, forming a new hole electron pair,under the action of the PN junction electric field the cavity.The N region flows to the P region, and electrons flow from the P region to the N region, and a current is formed when the circuit is turned on.This is how the photovoltaic effect solar cell works.The spectral response of a typical photovoltaic module is in the range of (320-1100 nm). Below I am attached to the common spectral wavelength range:

          It can be seen from the figure that the visible light wavelength is between 380 nm and 780 nm, and the response wavelength of the photovoltaic module is significantly larger than this range, so the solar panel is still generating electricity continuously, but the power generated is relatively small. So integrated solar street light china will glow when it is cloudy, but the luminous efficiency may be reduced.
