What You Always Wanted To Know About Solar Technlology
Life on earth is fueled by the light and heat from the sun. Approximately, 3850 Zettajoules (ZJ) per year is the total amount of solar energy available to the earth. Though the frequency range is different, the suns energy travels via electromagnetic radiation similar to that of radio waves. Heat and light are the primary forms of solar energy.Some of this energy is absorbed as it comes thru the atmosphere. Solar energy has many advantages over conventional energy. The energy from the sun is free the only expense is from recovering the energy. Recently solar photovoltaic technology is on the rise.
The cost of recovering the suns energy is recovered faster than with conventional energy. Recovering units do not need to be connected to gas lines or power lines. They are intended to work by themselves. There is an umlimited supply of solar energy and there are no gases emitted to hurt the earth or its atmosphere. There are several ways to recover solar energy: Focusing collectors: This has a movable mirror, known as heliostats, is pointed to the sun and can provide a temperature around 4000 degrees C. This degree temperature is used for a solar furnace in industries and research. These solar furnaces don’t contaminate our environment.
The heliostats can focus the energy to a boiler that turns water into steam. To generate electricity from solar power, focusing collectors can be used.
Flat plate collectors: These solar power panels can be used in schools and homes to provide heat using water that is heated in pipes. Since they are not as large, they will provide less heat than focusing collectors. Solar distillation: Solar distillation is about the same as flat plate collectors but provides distilled water instead of heat.
Sea water is put in tanks or ditches on the roof of a house and the heat from the sun heats and evaporates the water and turns the water vapor into liquid water that is distilled. Solar electricity: The use of focusing collectors and photovoltaic cells, made with thin pieces of semiconductors can make radiation form the sun into electricity. Since it doesn’t cost anything and doesn’t harm the environment, solar energy is not impacted by the supply and demand for fuel. It is unprocessed and unadulterated. It would engender in us a generally higher level of fitness. Together, there are a multitude methods we may implement to achieve optimal output of natural and renewable resources.
Going with solar energy is motivational to others who want to make a difference. The cost of solar energy is less than using gas, electricity, or other types of resources for heat. Even with the low up front cost of gas and electricity, you will end up paying more in the long run. With solar power you may have an initial investment to turning your home into solar power but after that you have no reason to pay for it any further, unless you use electric or gas for a back up heating source. Solar power was available yesterday, it’s available today and hopefully it will be available for us in the future.
