The fundamentals of building home solar power systems

Alternative energy is a really hot topic these days. People are trying to find methods to decrease their ecological footprint by discovering alternate ways of creating energy. One of these methods is to use solar panels to convert direct sunlight into usable energy. These solar panels could be affixed to the roof of your current house, absorbing as much sunlight as feasible. Other configurations such as on the floor mountings are also possible. These panels usually come in an array of 8 or much more, to ensure that sufficient energy is supplied to your home.

The real fascinating concept behind these solar panels is the solar cell that powers them. Solar cells are devices that are built entirely from solid material and in which the electrons or charge carriers are confined entirely inside the solid material. They convert the energy given by direct sunlight into electricity by a process known as the photovoltaic effect.

Photovoltaics is really a widely utilized technique of creating power by converting sunlight into direct current electricity, using semiconductors which can exhibit the photovoltaic effect. As mentioned above, photovoltaic power generation is only possible via solar panels, which are basically composed of a number of solar cells, which contain this photovoltaic material. You will find numerous materials that are presently used for photovoltaics, which include monocrystalline silicon, copper indium selenide, cadmium telluride or amorphous silicon.

The photovoltaic effect was really first discovered in 1839 by French physicist A. E. Becquerel. It was as early as 1883 when the first working solar cell was built by Charles Fritts, who accomplished this by coating the semiconductor material selenium having a very thin layer of gold to make junctions. The device was merely 1% efficient in converting sunlight to usable energy. The growing demand of renewable energy sources has increased the manufacturing of solar cells and photovoltaic arrays. Because of this, technologies of photovoltaic arrays and solar cells has advanced substantially in recent times.

A collection of cells are used to produce solar modules, which are known as solar panels to most people. These solar cells are grouped together on a grid to absorb as much sunlight as possible. When these solar cells begin collecting solar energy, they begin making energy, known as solar power. When solar cells are electrically linked together, they are referred to as a module. These photovoltaic modules most often have a sheet of glass on the front side, which permits light to pass through while protecting the semiconductor wafers from sharp abrasion or impact from wind-driven debris, rain or natural elements. The cells could be connected in series or parallel, permitting the generation of direct current. It's known that when these cells are connected in parallel, they usually yield greater current.

To actually use the energy produced by these solar panels, the electricity is injected into the electricity grid utilizing inverters or stored in a battery to be utilized when required. Solar panels have several applications, from charging your automobile battery to your phone. If you wish to reduce your energy bill and assist the earth, one factor is definite; solar panels are the way to go.
