SHC high-performance tube collector with 10 tubes

Our SHC high-performance collectors are equipped with special tubes with a high-quality mirror on the back. This mirror differs from cheap mirrors on the one hand by its size and on the other hand by its material. This mirror reflects the sun's rays onto the back of the tube, even when the sun's angle of incidence is low. This significantly increases the operating area and the vacuum tube supplies considerably more energy to the collector.

Our mirrors

Our mirrors are not made of conventional aluminium or cheap reflector material, but of a special aluminium composite. As a result, the efficiency of the aperture area is significantly higher than that of our competitors' products. These mirrors have an energy efficiency of 0.4 to approx. 0.5. The CPC mirrors used in our high performance collector achieve a value of 0.66. In addition, the aperture area is increased by the special shape, which offers an optimal reflection area even with unfavorable solar radiation angle.

Our Tubes

Copper coating (ALN/AIN-SS/CU) evaporated: This layer makes it possible that much energy can be absorbed, our tubes are characterized by a high stability and withstand even larger hailstones.

Functionality of the vacuum tubes:

The vacuum tube consists of two glass tubes with different diameters. This is a special glass made from borosilicate. Between the glass tubes there is a vacuum which is necessary to insulate the inner tube (the so-called "heat pipe principle"). In the inner tube there is a copper tube, which in turn is filled with a special liquid that absorbs heat.

The heat of the sun's rays heats the liquid and rises as hot steam to the tip of the copper heating tube. The heat generated in this way is then released in the collector and used to heat the hot water. The collector itself is made of aluminium and is insulated inside with rock wool at high temperatures, so there is hardly any loss of energy. Each vacuum tube is individually connected to the collector as a dry connection. This means that the pipes can be replaced individually without having to drain the liquid out of the system.

Difference between our solar system with ALN/SS/CU coating, systems with AL/N/AL coating and flat collectors.

ALN/AIN-SS/CU - 360° degree copper plating inside the tube

AL/N/AL - 360° aluminium coating inside the tube
