This can be done on perfboard too.
Solar motion sensor light circuit.
A solar motion sensor light usually features a metal frame and is typically positioned so that it can receive maximum solar power.

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.
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.
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.
The circuit is totally automatic.

1 x 3 7 volt battery at least 4 5 volt solar cell in.
The solar panel sits at the top perpendicular to the wall that the unit is mounted onto.

1 x 1 2 volt battery at least 1 5 volt solar cell in full sun.
The light is designed to be mounted on a wall that has direct visibility to the sky above it.
