What Is Solar Energy 
Solar energy is the light and radiant heat from the Sun that powers Earth's climate and weather and sustains life.
In simple terms Solar Energy is "Energy from the sun".
Solar energy means using the energy of sunlight to provide electricity, to heat water, and to heat or cool homes, businesses or industry.
Sunlight is a clean, renewable source of energy. It is a sustainable resource, meaning it doesn't run out, but can be maintained. Coal or gas are not sustainable or renewable: once they are gone, there is none left. More and more people are wanting to use clean, renewable energy such as solar energy and therefore install Solar Energy System. It is called 'Green Power'.
Photovoltaic (PV) solar cells directly convert sunlight into electricity. PV cells are combined into modules called arrays, and the number of arrays used determines the amount of electricity produced.
Photovoltaic technology converts sunlight into electricity and is emerging as a major power source due to its numerous environmental and economic benefits and proven reliability.
