Solar energy is one of the oldest forms of energy used by humans. Historical records indicate that as early as the 7th century B.C., people used simple magnifying glasses to concentrate the sun's rays to make fire or burn ants.
The sun provides more energy to Earth in an hour than the entire world uses in a year. In fact, the amount of sunlight that strikes the Earth's surface in just one and a half hours is enough to handle the entire world's energy consumption for a full year.
The efficiency of solar panels has improved remarkably over the years. While early solar cells had an efficiency of around 6%, modern panels can achieve efficiencies greater than 20%.
