Circuit diagram of solar garden light.
Solar panel circuit board.
Between the two is a reverse blocking diode.
This one way valve allows current to flow from the solar panel to the battery but does not allow current to flow backwards out of the battery through the solar panel.
It is built around a solar lamp controller ic cl0116 ic1 a miniature solar cell a bright white led led1 and a few other components.
In this circuit the solar panel charges up a 3 cell nimh battery 3 6 v.
When these boards fail there is often visible damage to the board.
The top countries of supplier is china from which the percentage of solar circuit board supply is 100 respectively.
This circuit requires only a single ni cd rechargeable battery to light up the white led for more than five hours depending upon the ampere hour ah capacity of.
