Cleaning at lofty heights – this is the goal of the TG hyLIFT GmbH from Gronau. With their machines, they are already conquering the glass roofs and facades of the world: from Spandau station in Berlin to a modern shopping centre in Spain. The concept behind this is semi-automatic and easy-to-use cleaning machines. The company has developed the "hyCLEANER black SOLAR" specifically for the thorough cleaning of solar plants. Engineers rely on the light, lubrication-free and maintenance-free polymer plain bearings from igus in both the wheels and the brush mount.
Solar and photovoltaic systems ensure the worldwide production of clean energy. The solar plant surfaces must be clean so that they can work with optimum efficiency. Mainly used in agricultural areas, they are subject to regular dirt accumulation through environmental influences during harvesting and ammonia vapours due to livestock farming, which reduce the economic efficiency of the surfaces. The performance of solar plants of private operators are also affected in cities by fine dust and pollen, which cannot be washed off by a rain. Even local dirt accumulation of individual cells by bird droppings or lichens can reduce the efficiency of the entire system due to the series connection, since the weakest module determines the overall performance. This means a loss of 20 to 30 percent in numbers in the worst case. But the financial loss is not the only problem: dirt can even damage the coating and seals, which can lead to a total failure.
