1. Solar energy is the most abundant energy resource on earth – 173,000 terawatts of solar energy strikes the Earth continuously. That's more than 10,000 times the world's total energy use.

2.The first silicon solar cell, the precursor of all solar-powered devices, was built by Bell Laboratories in 1954. On page one of its April 26, 1954 issue, The New York Times proclaimed the milestone, “the beginning of a new era, leading eventually to the realization of one of mankind’s most cherished dreams -- the harnessing of the almost limitless energy of the sun for the uses of civilization.”
3. The space industry was an early adopter of solar technology. In the 1960s the space industry began to use solar technology to provide power aboard spacecrafts. The Vanguard 1 -- the first artificial earth satellite powered by solar cells -- remains the oldest manmade satellite in orbit – logging more than 6 billion miles.
4. Nigeria lies within a high sunshine belt and within the country, solar radiation is fairly well distributed. The annual average total solar radiation varies from about 3.5KW/h per meter square daily in the coastal latitude to about 7.0KW/h per meter square daily in the north. Thus over a whole year, an average of 6,372,613 PJ/year or 1,770,000 TWh/year on the entire land mass of Nigeria, which in about 120,000 times more than the total electrical energy generated by the country in 2002.
