Will solar street lights be on during the day? What is the reason why solar street lights have been on during the day?
1. Will Solar street lights be on during the day?
The street lights are generally light at night, and Solar street lights are no exception. Under normal circumstances, Solar street lights will not light up during the day.
During the day, Solar lamps are a state of absorption. When the night is darker, and the requirements of the Solar street lights are light, it will start to light up to meet the normal use at night.Generally, Solar street lights control the switch through voltage. If there are some special circumstances, the output voltage of the Solar street lights is lower. In the set value, the Solar street light will also glow during the day.
2. What is the reason why Solar street lights have been on during the day
Normal Solar street lights will not light up during the day. If the Lights are on during the day, it means that the Solar street lights are broken, and there are many reasons that may cause this situation:
1. The Solar panel does not pass the controller to charge the battery during the day
The controller detection: The red light on the controller indicates that it is charging, and the red light shining indicates that the battery is now full, and the controller is charging with a small current of the pulse.
Solar panels: If the connection of Solar panels is not very strong, it will not be able to charge normally. Generally, there is a voltage (voltage meter test), the normal opening voltage is above 17.5V; but there is no current.This phenomenon is that the wires of the battery plate are not connected (virtual welding or unconnected joints). After the investigation method can be opened directly at the black electrical cover behind the battery plate, and directly use the voltage and current meter to detect the data.If there is no current from the aluminum pool detection directly from the battery plate, it means that the battery board has problems to be replaced.
2. Object cover
If the Solar panel is covered, it will also cause Solar street lights to be unable to use normally, covering snow, and the cover of dust.When these masks cover the Solar panels, the output voltage of the Solar panel will be lower than the certain value, and the Solar street light will be triggered.
3. Optical resistance control control
The light -sensitive resistance is particularly sensitive to light. When the light is weak, the resistance is large, and the resistance value decreases as the light becomes stronger.After sliding the resistor, a balance point can be found. When the light is strong, the light resistance value is small.The use of photovoltaic resistance has certain disadvantages.The light -sensitive resistance has high requirements for installation, and it is prone to accidental control under rainy days, cloudy and other conditions.
4. The voltage of Solar panels is wrong
The Solar panel transforms the Solar light into electrical energy. The stronger the light, the higher the output voltage, and the weaker the light, the lower the light.Therefore, many Solar street lights use the output voltage of the battery plate as the control signal. When the voltage is lower than a certain degree, the street light is turned on, and the street light is turned off when the voltage is higher than a certain degree.If there is a problem with the voltage of the Solar panel, when it is lower than a certain degree, the Lights will be turned on during the day.
