Solar power is the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP). Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Photovoltaics convert light into an electric current using the photovoltaic effect.[1]
The consumption of non-renewable sources like oil, gas and coal is increasing at an alarming rate. The time has finally come to look after some other renewable sources of energy i.e. solar, wind and geothermal energy. Although many countries have started utilising solar energy extensively but still they have to go a long way to exploit this energy to fulfill their daily demand for energy. Here are few facts on solar energy that can help you assess the potential of solar energy to meet global requirements.
Solar energy refers to energy from the sun. The sun has produced energy for billions of years. It is the most important source of energy for life forms. It is a renewable source of energy unlike non- renewable sources such as fossil fuels. Solar energy technologies use the sun’s energy to light homes, produce hot water, heat homes and electricity.
The main benefit of solar energy is that it does not produce any pollutants and is one of the cleanest source of energy. It is a renewable source of energy, requires low maintenance and are easy to install. The only limitation that solar energy possess is that it cannot be used at night and amount of sunlight that is received on earth is depends on location, time of day, time of year, and weather conditions.
