Solar Light/Charger

Not sure if this would be of any use to anybody but this is the
circuit I am using at the moment to turn on and off my outside
light from the 12v batteries.
It uses the solar panel as the light detector and as the battery
charger.
Please note there is no voltage control on the battery.
When the solar panel voltage drops to about 0.65v then the light
is switched on, Rise above this voltage and light will turn
off... reach about 13v and the battery is re-charged. Known as a
Dusk to Dawn Switch.
Output with values shown should be good for about 10A with a
heat sink (I only pull about 300ma with mine).
First picture is the circuit and light on.
second picture is the circuit + light off and battery being
charged.
It really is just an overgrown Garden Solar Light.
