Transcription

1 Cost effective The technology eployed in the production of P Standard has been carefully selected to achieve the optiu balance between functionality and reasonable price. Solar flat-plate collectors Standard Standard collectors are an ecological and cost effective solution for doestic hot water supply during the war season. The collector absorbs solar heat and eits it to the heat carrier circulating in the pipe harp. igh grade aterials Copper is irreplaceable when it coes to heat transfer. The liquid tight harp of copper tubing ensures high efficiency and reliability. Solar-grade heat tepered glass Durasolar P+. The glass used in flat-plate collectors is distinguished by decreased iron content providing for better transparency to the sun rays. Durasolar P+ has pris textured surface, which directs even the rays reaching the glass in unfavorable angle straight to the absorber. Insulation of rock wool keeps the heat fro leaving the collector body. Durable construction The collector case is ade of robust aluinu frae, and the botto is ade of ebossed aluinu sheet. This way the collector body has the necessary constructive strength to withstand the year-round whis of weather not sacrificing on light-weight Versatile ounting options Portrait and landscape odifications are available; two types of sleeves; options for installation on flat or inclined roof. 6 7

The inner tube surface is covered with selective coating allowing axiu absorption of sunlight and high perforance efficiency. Through the center of the heat pipe runs a hollow copper tube, inside which begins the process of evaporation of non-toxic fluid that transfers the heat to the tube top and then releases it to the collector pipe to heat up the heat-carrier inside. Then the process repeats over and over again. VTC VTC 0 VTC 0 Overall surface,6,, Aperture surface...

13 Polycrystalline coating Solar cells convert sunlight directly into electricity. This process of converting light (photons) to electricity (voltage) is called the photovoltaic (PV) effect. Solar cells are typically cobined into odules and a nuber of these odules can be ounted in PV arrays. Polycrystalline (or ulti-crystalline) cell based solar odules are now the ost popular choice in residential installs. Recent iproveents in polycrystalline odule technology have resulted in the developent in ters of size, efficiency and heat tolerance. ybrid collector PVT 0 The hybrid solar collector PVT is a cobination of a photovoltaic odule and a solar theral collector. This copact device converts solar radiation to electricity and heat siultaneously. igh energy yield, sall footprint and reduced installation costs are just soe of the benefits. igh grade aterials Copper is irreplaceable when it coes to heat transfer. The liquid tight harp of copper tubing ensures high efficiency and reliability. Solar-grade heat tepered glass is distinguished by decreased iron content providing for better transparency to the sun rays. The collector case is ade of robust aluinu frae. This way the collector body has the necessary constructive strength to withstand the year-round whis of weather not sacrificing on light-weight Two in one PV cells need solar energy to generate electricity at their axiu capacity, however, they deand low abient teperature to operate efficiently. As there are seldo such conditions in nature, regular PV odules can hardly be found to operate at their axiu capacity: igh solar activity is norally available in the war seasons when the surface of the regular PV odules heats up in result of being exposed to direct sunlight. Only -0% of the radiation that falls upon the surface of the odule is utilized to produce electricity, and the reaining energy is wasted as eitted heat. The PVT works around this issue as its cells are constantly cooled own by the theral absorber passing behind the cell layer. The excess heat fro the cells is utilized for production of doestic hot water. Versatile ounting options Options for installation on flat or inclined roof. ) 0
