Solar Energy

Solar energy has had a huge impact on the world since it was implemented. It provides essentially free energy upon installment. The sun 100% powers the panels which then travels through the tube inside of them, and is converted into energy to power anything from a toaster to the entire house. It is a safe, cheap, and environmentally friendly way to power appliances inside of your house. If I had the chance to put them on my house, I would do it in a instant.

They are a great bang for your buck and most of them pay themselves back within 10-15 years, which really is not a long time if you are living in the house for the rest of your life. For larger houses and owners of mansions and estates, solar panels are essential. With a large number of them, they can completely power the complex with ease, costing the owner a small sum for the power they are exerting. Solar panels burst onto the scene about 10-15 years ago. At first people were skeptical about the idea of sun powered energy, but once the kinks and details were further researched and more user friendly, they became a huge hit.

The great invention of solar panels, if used in mass quantities in deserts and large open plains, could potentially power entire cities. This could solve the world’s’ natural gas problem, and more people would have access to clean and free energy. Solar energy is a free, inexhaustible resource, yet harnessing it is a relatively new idea. The ability to use solar power for heat was the first discovery. A Swiss scientist, Horace de Saussure, built the first thermal solar collector in 1767, which was later used to heat water and cook food. The first commercial patent for a solar water heater went to Clarence Kemp of the US in 1891.

This system was bought by two California executives and installed in one-third of the homes in Pasadena by 1897. Producing electricity from solar energy was the second discovery. In 1839 a French physicist named Edmund Becquerel realized that the sun’s energy could produce a photovoltaic effect. In the 1880s, selenium photovoltaic (PV) cells were developed that could convert light into electricity with 1-2% efficiency but how the conversion happened was not understood. Photovoltaic power therefore remained a curiosity for many years, since it was very inefficient at turning sunlight into electricity.

It was not until Albert Einstein proposed an explanation for the photoelectric effect in the early 1900s, for which he won a Nobel Prize, that people began to understand the related photo-voltaic effect. The practicality and environmentally safe nature of solar power is influencing people worldwide. Production of PV cells and modules increased threefold from 40 MW in 1990 to about 120 MW in 1998. There are only two primary disadvantages to using solar power: amount of sunlight and cost of equipment. But the positive effects by far outweigh the negatives that could come of the solar industry.
