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.

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.
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.

Is it possible to have a solar switch that comes on during the day and off at night.
I want to run a pool water pump but since my house is solar I don’t want to use power on rainy days or at night (times when not generating power)
Yes, you can always set up smart sensors to control exactly when should the water pump work.
For inspiration, you can check solar powered irrigation timers.
Some of them are connected to the internet and will adjust their watering frequency depending on the weather forcast.
