Automatic street light control using solar panel.
Automatic street light control system is a simple and powerful concept which uses transistor as a switch to switch on and off the street light automatically.
A very simple automatic solar light system for illuminating your garden passages can be built using some leds a rechargeable battery and a small solar panel.
With the aid of solar cell and battery is charged during day time and this energy is used for power street lights during night time.
So this problem can be overcome by using a simple circuit.
In addition if a solar tracker system is used we can attain maximum energy from the sun.
Major problem in some places is every evening a person has to come and switch on the street light and it should be again switched off in morning.
Implementation of automatic street light control using sensors and solar panel 3 international journal of engineering research and applications vol.
The system automatically switches on the lamps at dusk and switches them off at dawn.

Yes this may not be the situation in everywhere but exists in many places.
Solar powered led street light with auto intensity control circuit diagram solar panels.
It is a simple and powerful concept which uses transistor bc 547 npn as a switch to switch on and off the street light system automatically.
It automatically switches on lights when the sunlight goes below the visible region of our eyes.
By using this system manual works are removed.
For regulating the input ac supply there is a regulator section consisting of ic 7812.
These cells are available in two types.
There have been lot of problems in street lights.

In this ne 555 ic is wired as monostable multivibrator.
This project explains the system that automatically control the intensity of street light which is design using.
In solar powered automatic street light controller there is a provision in which the energy required to run the street light is provided by the solar energy.
It automatically switches on lights when the sunlight goes below the visible region of our eyes.
The result comprises the successful operation of the solar powered led street light with auto intensity control.
