Solar LED Lighting System

In this project, we have to tried to convert the solar energy into electricity. Solar lighting systems are powered by solar cells that convert solar energy (sunlight) directly into electricity. The electricity is stored in batteries and used for lighting whenever required. These systems are useful for non-electrified rural areas and also as reliable emergency lighting systems for important domestic and office applications.
The solar lighting systems for homes are fixed installations comprising a solar photovoltaic (PV) module or solar panel, charge controller, battery and lighting system. The solar module is installed in the open on rooftop exposed to sunlight and the charge controller and the battery are kept at a protected place inside the houses.
Special electrical properties of the solar cell provide the voltage needed to drive the current through an external load. Assemblies of cells are used to make solar modules, or photovoltaic arrays. Through metal contacts, an electric charge can be tapped. Here we use CD for mounting LEDs. Since CD are very good reflectors and so we mount 18 white LEDs on CD. The solar energy converts into light and glow the LEDs.
