| Flat solar collectors  Flat plate solar collectors have a large glass surface and a large absorber. In full sunshine, their power output is high. They utilize most of the solar energy that reaches their surface. The materials used guarantee a long service life and stable parameters of the collectors. All models are equipped with an anodized aluminum frame and a copper absorber with a long-life absorption layer (carried out by vacuum deposition). The absorption layer of these collectors has a highly selective surface. Its ability to absorb solar radiation is high but its heat dissipation (heat loss by dissipation) is very low. Solar tempered glass in all models is highly shatterresistant and permeable for solar radiation. KPW1 model uses solar antireflection glass that represents the best in solar glasses. A special coating on both sides of the glass eliminates reflections of solar radiation and the absorber receives more solar radiation. Thermal insulation limits the collector's thermal loss and increases its efficiency. The thickness of the mineral wool insulation is between 2 and 6 cm depending on the model. Regulus solar collectors are certified by an independent Test Lab according to the latest European standard EN 12975-2. This standard involves among others also measurement of the output and efficiency, of mechanical resistance including hail resistance and long-term weather resistance. write your comments about the article :: © 2011 Construction News :: home page |
