2 equipment for converting solar energy into electricity are still quite expensive. Only rich countries such as USA and Japan, to get to their widespread use. Curiosity Production of electricity derived from solar radiation takes place in two ways, first is to receive heating water and steam that drives turbine generators is used for the thermal while the second method uses a photoelectric solar panels inside the tensions arising in those barriers transform solar light energy into electricity

3 1. Transparent coverpreferably made of glass low content of these oxides iron. Probably not now apply coatings of plastic, because up relatively quickly deteriorate under the influence of high temperatures, UV radiation and can scratch them that lowers permeability Ä sun rays sunshine.

Probably not now apply coatings of plastic, because up relatively quickly deteriorate under the influence of high temperatures, UV radiation and can scratch them that lowers permeability Ä sun rays sunshine. The use of prismatic glass windows significantly to Improve Performance Ä collectors. 2. Absorber - Leading main element of the collector ordered words. It should be made of good conductive metal heat here, most often it is a world copper (preferably) or aluminum. The metal is coated with a substance by creating shell his eye. It dependents on the type of collector, coating of the eye is to be indiscriminate emit or selective Non-selective water-repellent coating performs now with black lacquer, now apply now so-called selective coatings coating TiNOX. Of course you shell coatings are much more selective. For flat plates are soldered absorber tubes, through which flow uses the working fluid.. 3. Isolation and housing - to the collector gave the heat to the environment, must be insulated. Used as an insulator is usually mineral wool or polyurethane. The whole is housed in a casing of the drain (usually aluminum), which should be tight.

4 For domestic water heating and heating support solar installations are used. They are a team matched each other devices such as solar panels, steering assemblies, suction and displacement water trays or trays buffer continuous flow heat exchangers. Properly selected and constructed solar installations allow you to save all year round about 65% of the energy needed to heat hot water and about 30% to heat the building. Seasonal installation can save up to 80% of the energy needed to heat hot water or water in the pool. Solar energy is converted into heat by the absorber, which by means of transmission factor is sent to the installation of hydraulic tray. Solar collectors are equipped with high-quality absorber which absorbs direct sunlight and diffuse. Special composition of the glass pane protects the absorber from damage, and significantly blocks the sunlight reflecting from the surface. The lower and lateral part of the collector is protected from loss with a layer of thermal insulation.

5 Once the investments in fixed e offset energy costs for a given object. Initially incurred expenditures bets very quickly compensates for now and allow lower Food costs average up to 70% savings enlarge those connected with the preparation of the annual cost of heat and hot water usable approximately 20% enlarge ning to heating. Economic calculation is so simple and became c e savings to you. The cost of installing sun sunny gold Olzon z flat plate collector is comparable to the cost of a traditional installation. If you, however, take into account Ä, lying further exploitation of collectors costs almost nothing, the investment quickly now points Italy reported actually designed to allow installation of tangible benefits to those who provide reduced operating costs to a minimum and sane Essential guarantees the fast depreciation. This makes lying sale solar systems significantly increases with each year and up main and approximately 40,000 m2 of active in 2005 Sun solar collectors successfully can be operated for at least 20-30 years with minimal maintenance for periodic (only solar fluid replacement fee)
