  What Is Solar Power?

While many people understand that the sun provides more power in an hour than the world can use in a year, they still wonder what is solar power good for and how can it benefit me? While the idea of using the power of the sunlight has been around for more than 100 years, it was not until the late 1970s that a genuine effort was made to learn about what is solar power and how it can help reduce the world’s reliance on non-renewable energy sources.

Oil, coal and natural gas will only last so long, and estimates of the remaining supply vary from scientist to scientist as well as from government to government. The emission of carbon dioxide and harm to the Earth’s atmosphere has resulted in cries concerning global warming with dire consequences predicted. By learning what solar power is used for, is making a difference in the conversion of solar power to electricity. 

Essentially, the suns rays are unfettered and uncontrolled beams of ultraviolet radiation and the first successful experiments in the 1890s and 1900s showed that the sun’s energy could be harnessed to heat water, turning it into steam to power mechanical devices such as a steam engine water pump. From those early experiments, what is solar power has been harnessed through the use of photovoltaic cells to convert the sun’s energy into electric power.

Advances In Technology Continues To Improve The Solar Power Process

While the first cells were exceptionally weak, today’s cells are capable of converting only about 15 percent of the energy absorbed into electric power. The direct current produced by solar cells is capable of powering devices requiring DC current, and inverters have been designed to convert the stored power into alternating current to effectively power devices designed to operate on AC current. The early questions about what is solar power good for are continuing to be answered by technicians worldwide.

Other natural resources are also being explored as renewable energy resources such as wind power and water, however water generation is limited to areas where there is a sufficient flow to operate turbine generators. Wind power is also growing in popularity in areas where there is a breeze most days of the year. Electricity being generated by what is solar power is the most popular, as and determined by researchers in 1890, the most likely source of consistent energy in the future. As a result, additional financial and technical focus will be placed on improving what is solar power over the next several years.
