The universal atmospheric pollution increase is caused by the burning of coal, oil and gas. Pollution and diminishing resources have brought about the search for ecological and inexhaustible energy. It has been shown that this problem may be solved by ready natural energy in the form of wind, water and sun. The only difficulty is the ability to convert natural energy into usable energy.
The energy source with the greatest predictability, which is accessible everywhere is the Sun. In order to convert it into usable energy, various types of solar panels have been constructed. One of the elements applied in practically all types of panel is the sheet, primarily intended to protect the internal elements of the panel, while ensuring the highest penetration of sunlight heat energy to photovoltaic cells.
Product range
The Press-Glas product range contains EcoGuard ExtraClear™ Plus, glass designated for solar collectors of thickness 3; 3.2 or 4mm, which is approved for use in solar collectors by the Instytut für Solartechnik SPF in Switzerland according to Standard EN 9500.
Perfectly selected raw materials, in particular the use of sand with low iron and silicon values, enables the achievement in ExtraClear™ Plus of a typical neutral appearance, but its specification far exceeds the requirements of Standard EN 572-2.
