Harnessing The Suns Energy
Posted by under Solar EnergySolar power technologies, the harnessing of the renewable energy of the sun for our electrical power, include the use of either photovoltaics or implementation of passive solar heating. Lets take a look at each.
Photovoltaics PV for solar power are solar cells whose purpose is to convert the light from the sun directly into electricity. These Photovoltaic cells are made of materials that have semi conductive properties. In their simplest forms these solar power cells energize calculators and watches.
The more complex photovoltaics can provide the lighting for entire homes and provide solar power to the local electric grid for a large portion of the local community.
Photovoltaics works at any time that the sun shines, although you'll get more solar power when it is a bright sunny day and when the rays of the sun are shining perpendicularly on the solar power panels.
Unlike a solar power system that is used to heat water, the technology of Photovoltaics doesn't use the rays of the sun to make the electricity. What it does instead is produce the electricity right from the electrons that are freed by the sunlights interaction with the PV cells semi conductive materials.
You don’t need a Ph.D. in physics to implement solar power and take advantage of all its benefits. Investing in PV gives you the chance to produce your own power, pollution-free and without any moving parts to worry about. Solar power is a renewable energy resource that is entirely clean. Not only that your solar power system will not run out of fuel unless we run out of sun.
Another source of solar power, passive solar power, can heat or your home and light it as well. Residences and commercial buildings that have implemented this passive solar power use simple methods such as windows that face south and building materials that absorb the heat of the sun and then release it slowly.
With simple passive processes and implementations residences can realize a reduction of up to half of their home’s heating bill. Natural ventilation to cool that home is also part of passive solar power as well.
