 Solar Energy is a renewable and unlimited source of energy which directly or indirectly delivers most of the other sources of energy to Earth. Solar energy in the narrow sense means the amount energy that is transmitted by solar radiation and is expressed in J. Solar energy in its original form is commonly used for conversion into heat energy for domestic hot systems water and heating (as additional energy source) and in solar power where for conversion of electricity is using photovoltaic systems. |

By: Mike Townsend  Many homeowners are turning towards alternative solutions to meeting their energy needs because of the rising energy costs sweeping the country and the world. Solar power for the home is one way a lot of people are saving money. Having solar power for the home installed may be a very expensive undertaking if performed by an expert. A lot of people, however are not aware that they can put in solar panels by themselves. If you 'do it yourself', you the homeowner, will enjoy all the benefits of solar power without paying installation fees.

 Passive solar design takes advantage of both summer and winter sun angles for free cooling in the summer and heating in the winter. How cool (or hot) is that?
Passive solar gain,... it's free and completley pollution free! It can be as simple as paying attention to the orientation of the house, placement of windows, the length of the overhang of your roof, and the kind of floor and walls chosen. One way of thinking about your house when it comes to the sunshine that falls upon it everday is like that of a battery. How efficient is your house as a battery, that is, how well does it charge up and save the free heat that the sun provides during the day and how well does it give back this heat during the night when needed?

 Photovoltaic cells - those black squares an array of which comprises a solar panel - are getting more efficient, and gradually less expensive, all the time, thanks to ever-better designs which all them to focus the gathered sunlight on a more and more concentrated point.

 Light (particularly sunlight) can be used to create heat or generate electrical power. This is referred to as solar energy. It is a clean form of energy production, which doesn't pollute the environment as some other forms of energy production do. There are two forms of solar energy. The first is solar thermal conversion, which uses sunlight to create heat and then electrical power. The second is photovoltaic conversion, which uses sheets of special materials to create electricity from the sun. "Photo-" means "light," and "voltaic" means "producing electricity."

 Solar power is the generation of electricity from sunlight. We use photovoltaics, or indirect with solar acumulators to concetrate solar power, sun's energy is focused to boil water which is then used to provide power. Photovoltaics directly convert light into electricity using photoelectric effect that causes to absorb photons of light and release electrons. When we are able to capture free electrons it creates the electricity.
