ABSTRACT
As the
sources of conventional energy deplete day by day, resorting to alternative
sources of energy like solar and
wind energy has become need of the hour.
Solar-powered lighting systems are already available in rural as well as urban areas. These include solar lanterns, solar home lighting systems, solar streetlights, solar garden lights and solar power packs. All of them consist of four components: solar photovoltaic module, rechargeable battery, solar charge controller and load.
In the solar-powered lighting system, the solar charge controller plays an important role as the system’s overall success depends mainly on it. It is considered as an indispensable link between the solar panel, battery and load.

In the solar-powered lighting system, the solar charge controller plays an important role as the system’s overall success depends mainly on it. It is considered as an indispensable link between the solar panel, battery and load.
The microcontroller-based solar charge controller described
here has the following features:
1. Automatic dusk-to-dawn operation
of the load
2. Built-in digital voltmeter (0V-20V range)
3. Overcharge protection
4. System status display on LCD
5. Low current consumption
6. Highly efficient design based on microcontroller
