How Do Solar Lights Automatically Work At Night

If you need to learn more about how do solar lights automatically work at night, then you come to just the right place.

In the article, we will talk about How Do Solar Lights Turn On Automatically at Night and off in the morning.

So without further ado, let’s jump right into it.

How Do Solar Lights Turn On Automatically at Night?

When it comes to solar lights, one of the most asked questions is how do solar flood lights work automatically at night.

Well, the answer is pretty simple.

Solar lights are equipped with something called photosensors, which are electronic components that detect (sense) sunlight.

The solar light’s photosensor works as a gate between the rechargeable battery, and the LEDs.

When the sensor detects no sunlight (night), it connects the circuit between the battery and the LEDs allowing the battery to power the LEDs.

As a result, the solar flood light will automatically turn on at night.

How Do Solar Lights Turn Off Automatically In The Morning?

Similarly, when the photosensor detects sunlight (dawn), it cuts the circuit between the battery and the LEDs preventing the battery from powering the LEDs .

Thus, the solar outdoor light will automatically turn off in the morning allowing the solar panel to fully charge the batteries.

Why Are My Solar Lights On During The Day?

If your solar lights stay on during the day this means that your photosensor is faulty and it will sense no sunlight.

In other words, your light will act like it’s already dark connecting the circuit between the LEDs and battery resulting in an always-on solar light.

For this reason, your light sensor must be replaced. Don’t worry, photosensors are very cheap and you can replace it by yourself at home.

Types Of Solar Lights Photosensors

Solar lights use many types of sensors and in this section we will go through the most common ones.

  1. Light Sensor: This one is responsible for automatically turning on the lights at night
  2. Lux Sensor: This sensor controls how dark it has to be outside before turning on the light. In other words, it senses light intensity and you can easily adjust it to your preferred settings
  3. Passive Infra-Red (PIR): This sensor can be found in motion-detecting and security solar lights and it mainly senses the heat. Without overwhelming you with such technical details, this sensor will activate the light when it detects someone near and it can be also adjusted
