Solar ideas

Sun is the closest star to Earth and energy from it which reaches the ground, should be used maximum!Why should we pay bills for electricity, gas or coal, once we can install solar collectors on the roof or in the yard and take infinite energy from the sun?

The amount of solar energy reaching the Earth for one year is more than twice the amount of energy that we get from burning all terrestrial stocks of traditional non-renewable energy sources such as coal, oil, gas and uranium!
Solar architecture, construction and planning are known to the ancient Greeks and Chinese, but in the modern era of high technology using solar energy is becoming more efficient equipment is more accessible and so the systems reach the ordinary home.
Solar collectors for "collection" of solar energy are two types - thermal / direct heat water for domestic use / and photovoltaic - to generate electricity from silicon cells that comprise the panel. Photovoltaic principle is that the penetration of light photons in the structure of the silicon plate, they are converted to electrons, electrical current flows, which could be used directly / lighting, water heating, for various appliances, motors, pumps and etc. /. and also be stored in storage batteries for later use.

How much energy or power we need and whether it can obtain it from the sun? Are sense installations of photovoltaic solar elements in the houses and buildings? How much is this equipment? These are questions that involved many people in recent times as interest is fueled by rising electricity prices and energy carriers, but also for environmental reasons for reducing greenhouse gas emissions and less use of traditional fossil energy sources and the desire for energy independence.

Generally it is considered that one occupant of the house is required about 1 kW - for lighting, appliances, home appliances and other things.
This means that a family house with a normal family needs about 2,5 kW installed capacity. The systems usually consist of a solar roof modules mounted with a southerly orientation / depending on the implementation example for 2,5 kW, it takes about 16 pcs. panels of 150 W which with standard size around 140h80 cm or about 20 sq.m. /, control electronics, battery energy storage for night or cloudy days, inverters device that converts electricity into a 220 V voltage, suitable for standard use. The cost of such a system is around € 8,000 at today's prices of components. Must take into account the fact that it is well a solar house is designed in advance such as electrical and it is thought through and designed so as to work optimally with the solar power! Of course, this does not mean that an existing building can not be installed solar system - will simply have more complications and need for new cables and organization.

As an ideology until there are several categories of solar houses:completely energy-independent house in which they provided more modules and equipment, ie power, so as not to rely on external power to "serious" momentsnormal solar houses with an average amount of installed power panels and equipment / as the example above, / who used the aid of external power supplier elekroenergiya. In Western Europe and the U.S. is becoming increasingly popular scheme to reward the use of solar electricity in their homes - when operating system and generates energy house consumes necessary and what is more, is redeemed by elektrodostavchika. It is very simple - a round trip meter. In practice, when the house needs energy / eg night / meter rotates and generates the consumer ... When the house is more than necessary energy / on a sunny day /, she attaches to the network and the meter is spinning in the opposite direction - ie, elektrodostavchikat pay the owner for purchased energy.solar houses with a few small panels that use solar energy for lighting, for example, to power the computer and TV .

Moreover, as the electricity price is still relatively low and the incentive to invest in green energy / which is more expensive as the equipment for producing it / is not there!
Nevertheless, the future is clear - namely the use of renewable solar energy, environmental protection and planning of buildings so as to gain their necessary energy. A matter of time only installation and integration of solar panels in buildings to become standard and we can not imagine how we lived without this source of green, clean, infinite energy and free!
