More alternative kinds of energy sources are getting actively discovered largely because of the reason that the global warming crisis for our planet is increasing. Solar Panels Brisbane This reason is being aided by use of devices and mechanisms such as wind turbines, solar PV panel and geothermal and hydroelectric systems. Not much destruction is given to our environment when using these alternative energy unlike the burning of fossil fuels which is our main energy source.
An alternative energy that is gaining much recognition is solar power. Basically, what it does is harness the sun’s rays for domestic or commercial utilization. Since the power that the sun releases is free and does not need a far-reaching harvesting procedure, the solar technology industry is expected to grow in the next couple of years.
Solar Energy Background
Heat for warmth and for cooking was required by man long ago. This was given by the sun. Only recently was its full potential discovered when more in-depth research and testing was done.
Because of his theories that explained the solar PV or photovoltaic effect, Albert Einstein claimed a Nobel Prize in 1923. Before that, Charles Fritts first defined this effect in 1883. When referring to photovoltaics, it talks about the sun (photo) and electricity (voltaic). The electricity produced from the sun through the use of solar panels describe this effect.
The Applications of Solar Energy
The most common uses of solar energy are listed below:
Solar heating for pools
Solar heating for pools is the biggest in capacity that uses solar alternative energy in the United States. To be able to heat large quantities of pool water, thermal collectors, a circulation pump and flow control valves are required.
Solar water heating
Says the Solar Energy Industries Association, ten per cent of homes in China use solar heating.
Generation of Direct Current (DC) electricity
Small devices like calculators, laptops, MP3 players and mobile phones can be powered by direct current electricity generated from solar PV cells. These cells cam also be used for solar panels that provide electricity to power homes and offices.
Generation of Alternating Current (AC) electricity
Heat can be concentrated and used to generate steam from water to power turbines that would supply the AC electricity. Residences, buildings and commercial spaces may also be given their electrical requirements when this AC current is contained within power grids.
It is evident that solar energy is a technology of . Countries such as Spain, Germany and the United Kingdom even give feed-in tariffs (FiTs) and incentives for people who use solar panels and solar PV systems.
