In direct sunlight at the surface of the equator, a maximally efficient 
photovoltaic cell about 1/5m in diameter creates a current of approximately 2 amps at 2 volts, however, due to the Earth’s atmospheric interference, terran solar panels will never perform as well as solar panels exposed directly to the sun’s rays.
Years of overheating and physical wear can, however, reduce the operation efficiency of the photovoltaic unit. Solar panels become less efficient over time, and excess energy is released into its thermally conductive substrate as infrared heat. The amount of power solar panels produce is influenced by the quality of the solar panel, the materials and technology used in making the solar panel, and the amount of time the solar panel has been in use. When purchasing solar panels, it is therefore wise to look beyond size and look at the dollars/watt ratio.

The sun endures a continuous stream of thermonuclear explosions as hydrogen atoms are fused into helium atoms. We encounter the resultant energy as radiation that strikes the surface of the earth. Solar panels convert this solar radiation into useful electrical energy and store them in batteries for our use. Enough solar radiation strikes the earth every day to meet earth’s energy needs for an entire year. Solar panels help us harvest this energy and convert it into usable energy to meet the everyday needs of modern life.

William Fetter was credited with coining the term computer graphics in 1961[1][2] to describe his work at Boeing. One of the first displays of computer animation was Futureworld (1976), which included an animation of a human face and hand—produced by Ed Catmull and Fred Parke at the University of Utah.
