A Detailed Guide to Ways Solar Panels can Help You Cut Down on Utility Bills

Our planet receives about 174 petawatts of heat radiation from the sun. Solar energy is free energy we can use. About 30% bounces back to space while clouds, land and bodies of water absorb the remaining radiation. This totals to about 3,850,000 exajoules of sun energy absorbed by Earths atmosphere annually.

The power that comes from the heat of the sun is very useful to people since the olden times. It does not cause any pollution and it does not require any fuel in order to be utilized. This solar energy is free energy.

The heat from sun that reaches our planet is twice as much as the amount of power that will be harnessed for a very long time from natural gas, coal and oil. Due to this advantage, modern solar technologies are presently being used to harness power. Some solar applications used nowadays are water heating, heating and cooling architectures, electricity production, cells powered satellites and for industrial purposes.

Today, many buildings are structured with the use of passive sun heating. They usually have large windows made up of materials that absorb the sun heat. It then stores the collected sun heat to the walls and the floors. These will then slowly give off heat during nighttime when its cold. Through the use of this natural source, building owners are able to save up a large amount of money.

Power plants are also taking advantage of sun power. Before they use fossil fuels but now they use power systems from sun heat. These include the parabolic-through, powered tower and dish.

Parabolic-through collect power from the sun with the use of skewed U-shaped mirrors. These focus light and heat to the pipes that has oil in it. The oil then in turn heats the water which is used by the generators to produce electricity. The dish system and power tower system has sort of the same concept in electricity production.

Aside from heating, this is also used as a cooling power source. Like an air conditioner, cooling devices generate power from the heat. Aside from this, evaporative coolers also use this for its power source.

Water heating has also been a famous use of sun power. Glass panels in roofs are used to heat water. Through this, gas or electricity will be saved. Pipes in the panel contain water. Water is propelled from the bottom which helps hot water to be pumped from the top.

As a free source of power, the cells are utilized by our satellites as it orbits the earth. With these satellites, we are able to use TV, telephones, internet and different navigation system. We are able to enjoy these different applications everyday with the help of solar cell powered satellites.

We may not have taken notice of it but mankind has been using solar energy is free source of energy. Heat from sun has been used for drying clothes and foods. In the past, the heat from sun has not been fully utilized. But with the help of our modern technologies, we are able to use the heat as our free source of power. ;http://www.youtube.com/watch?v=vqKCh9GHdR0?fs=1&feature=related]
