Flat Panel collector
The flat panel collectors are mounted on the roof, in areas exposed to the sun. It is taken into account that in that place there should be sun for as long as possible during the day, not to be shaded by vegetation or buildings. The method of mounting the solar panels depends on the construction conditions on site and the customer's desire. From an aesthetic and architectural point of view, there are other mounting options, on a flat roof or terrace type, on metal supports, warehouses, garages, etc.
The advantages of solar flat panel collectors.
The solar flat panel collectors are distinguished by the long life, the high flow of recirculated thermal agent, respectively the fast heating capacity of the boiler. Also, in case of frost or ice, in cold periods, flat solar panels give off some of the heat, so the ice will be completely removed on the entire surface of the collector.
Flat panel collectors require solid fastening systems, usually made of aluminum. Roof fixing accessories can be ordered depending on the construction of the roof, flat or inclined.
The main component of the solar flat panel collector is the copper absorber (absorber) covered with a selective layer. It ensures efficient capture of solar radiation and reduced losses through thermal radiation. Under the absorber covered with a selective layer, there is a heat exchanger made of copper or aluminum, in the shape of a harp or serpentine, through which circulates the solar fluid, which takes the heat from the absorber. The solar collector is covered with safety glass, resistant to hail. Also, glass has a low iron content, which leads to increased transmission properties. Well insulated sealed housing.
