The solar security light.
Solar motion sensor light circuit.
So batteries and the circuit dictate the solar cell size there are some of these lights with pr sensors that use a 3 7 volt battery and a solar cell of 4 5 volts.
Like any solar energy device solar motion sensor lights work by harvesting the sun s energy to either power a light immediately or to store the energy for future use.
Ollivage solar lights outdoor motion sensor security lights solar wall lights with dual head spotlights 30 led waterproof 360 adjustable solar motion lights outdoor for garden garage patio 1 pack.
The light is designed to be mounted on a wall that has direct visibility to the sky above it.
The circuit is totally automatic.
The solar panel sits at the top perpendicular to the wall that the unit is mounted onto.

The figure beneath shows an automatic solar powered motion detecting sensor for outdoor lights.
A simple circuit controlled by two major things.
1 x 1 2 volt battery at least 1 5 volt solar cell in full sun.
The light itself sits at a slight angle while the motion sensor and button sit at a much steeper angle.
When pir sensor sense any human interference or ir light running 38khz.
When the pir sensor distinguishes anybody in its range.
2 x 1 2 volt batteries at least 3 volt solar cell in full sun.
The solar panel that sits on top.
2 pir motion sensor.
It will charge a 6v 1 2ah lead acid battery in the day time within the sight of daylight and enact the lights after sunset.
