Introduction
The main scope of project is, the photovoltaic cells are
converting the sunlight in to electricity a charge controller is used.
PV cells are bundled together in modules or panels to produce higher voltages and increased power.
As the sunlight varies in intensity the electricity so generated
usually charges through the charge a set of batteries for
storing the energy.

BATTERY
An electrical battery is a combination of one or more electrochemical cells, used to convert stored chemical energy into electrical energy.
The battery has become a common power source for many household, robotics and industrial applications.
Larger batteries provide standby power for telephone exchanges or computer data centers
MOSFET(IRF 510)
The metal–oxide–semiconductor field-effect transistor (MOSFET, MOS-FET, or MOS FET) is a device used for amplifying or switching electronic signals
The basic principle of the device a voltage on the oxide-insulated gate electrode can induce a conducting channel between the two other contacts called source and drain
It is by far the most common transistor in both digital and analog circuits, though the bipolar junction transistor was at one time much more common.
