Solar 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...
