The development of the solar panel can be traced back to the 18th century when Horace de Saussare created the first solar collector. He built this in the year 1776, and probably could never have imagined how things would develop in later centuries. In 1861, this creation inspired the first solar power steam engine. This break through didn't last very long but it did alert people to the potential of solar power.

During the 1880s, the first light converting photovoltaic cells were built. These cells were made of selenium and had an efficiency of one to two percent. In 1891, the first commercial solar water heater was patented by an American named Clarence Kemp. In 1921, it was for his work on photoelectricity that Albert Einstein was awarded the Nobel Prize.

Eventually, in the 1950s, solar power saw its first mainstream usage with the first solar water heated office building being built during this time by an architect named Frank Bridgers. Interestingly, the subsequent fall in oil prices during the 1960s saw to the decline in solar power usage and it was not until the oil embargo of the 1970s that solar power garnered strength once more as an energy resource.

The increasing prices of oil and global disasters such as the Gulf war have led to an ever increasing cost of oil. The push towards solar power continued and it is reported that in the 1990s over 1 million US homes had solar power panels installed.

In today's world, solar power is used in two major ways: photovoltaic conversion format and thermal solar power. Thermal solar power is where the sun is used to heat fluids, which then powers turbines or other types of machinery. Photovoltaic conversion format is the basis on which solar panels operate. These panels are used to create electricity directly from the sun and can be used alone or in conjunction with other power resources.
