Battery voltage 12 v 2.
Solar panel dusk to dawn circuit.
During broad day light the solar panel produces the required amount of voltage which is applied across the rechargeable battery via the 1n4007 diode and the resistor r.
In this next circuit we use the solar panel to charge up a nimh rechargeable battery and also led off of the power which will stay on when it gets dark out.
Solar streetlights can be easily integrated with a dusk dawn controller by simply employing a pnp transistor and a few resistors where the solar panel itself works as the sensor.
Selecting the current limiter resistor.
The product is for use with single 12v battery and can give charging current upto 10a 150w solar panel.
Solar charge controller 12v 10a for street lighting system dusk to dawn pwm charge controller is a low cost reliable product for use as solar street lighting system dusk to dawn opeartion.
Between the two is a reverse blocking diode.
