Solar PV (Photovoltaic)
Today's solar electric cells are a practical and environmentally friendly way of producing electricity for everyday use.
How it works
The cells or thin film circuits of the solar modules are specially manufactured to respond to light by producing electric current. The scientific term for " solar electricity " is " photovoltaic " energy-which means electricity from light.
The more light the cells get, the more electricity that can be produced. These cells when connected together, laminated and framed, are called a 'solar module' or sometimes 'PV (photovoltaic) modules'.
Solar electricity can be used to run DC motors, or it may be stored in batteries for later use, or converted instantly into AC power and 'net metered' into the utility grid.

Energy from the Sun
Using energy from the sun is the simplest and most popular method of renewable energy supply. The number of solar modules you need will depend on your energy requirements and your location.
The output from a solar module varies seasonally. Around twice as much power can be generated from a solar module in summer compared to winter
You may wish to install enough solar modules to meet your total load throughout the year. This will include extra solar modules to compensate for fewer sunlight hours in winter or you may decide to install fewer solar modules based on the yearly sun hour average.
