The sun is the most abundant source of energy we have on earth. It is 4.6 billion years old and considered to be the most reliable renewable source of energy which is not going to run out any time soon. Humans have been tinkering with solar energy since the dawn of time to light fire by concentrating sunlight with the help of glass or mirror. It wasn't until the 1950s, the technology was developed to convert abundantly available solar energy into electricity with the help of Photovoltaic systems cells. It can be used without releasing any greenhouse gases and other harmful by-products, making it the most eco-friendly way of extracting energy to be further converted into electricity. Solar energy is believed to have consistently grown by 33% in the last thirty years from 1979-2010. It is projected to cross over 40% of the total energy for this decade. Many solar installation companies have come up in the last few decades with huge investments made into this technology.
