Solar energy is energy obtained by converting solar thermal energy (the sun) with certain equipment to be a resource in another form.
Solar energy is one source of power generation in addition to water, steam, wind, biogas, coal, and petroleum.
Solar energy utilization techniques began to emerge in 1839, was discovered by AC Becquerel. He uses crystalline silicon to convert solar radiation, but until 1955 the method has not been developed. Over a period of more than a century, a widely used source of energy is petroleum and coal.
Back development efforts by utilizing solar energy emerged again in 1958. Silicon cells are used to convert solar energy into resources begin to be considered as a new method, because it can be used as a power source for space satellites
The application of solar energy
Solar energy has been widely applied in daily life. Some of these applications include:
- Solar powered lighting
- Solar powered heating, for heating water, space heating and cooling,
- Desalinization and desinfektisasi
- To cook, using solar cookers
