Produced by the on-line local action network, Endependence.info. Show us how you are saving energy. We’ll copy your great ideas. Energy independence, we can’t do it alone, but we can do it together.
Solar power technology uses the light of the sun to generate power. The sun is a major source of renewable energy and is available in abundance. Active solar technology uses electrical or mechanical equipment, such as pumps and fans, to manufacture the usable heat in a system. Passive solar power is derived from the rays of the sun without using mechanical devices or equipment. Direct sunlight can be used for heating, cooling or ventilating rooms or it can be stored for future use. Passive solar technology turns sunlight into heat which is used for various domestic purposes. The trend nowadays is to build environmentally –friendly homes. A good practice is to have the suns rays directly pouring into your house, so that you can have a solarium to conserve the heat of the sun, and use it whenever necessary. This is passive solar technology at its best, because all that is required is clear glass window panes incorporated into the design of the house.
It should first be noted that “solar powered pump” is actually a description of a two phase process. You have 1: the actual pump and 2: an energy source being powered by the sun, with a cable or wire connecting the two devices. Solar powered pumps can be used to pump water for humans, livestock or plants. Since the need for water is greatest on sunny hot days the technology is an obvious choice for this application.
