Nelskamp’s "SolarPowerPack" (SPP) is a visually inconspicuous power pack for heating and hot water. The solar collectors are identical in shape and colour to Finkenberg tiles, making them practically invisible on the roof. Thanks to their highly efficient technology, they supply the house with heating energy and hot water all year round.
The principle is simple: The collector was matched exactly to the profile of the Finkenberg roof tile. It is a double-walled, aluminium full-surface absorber with a powder-coated surface that is ready-mounted on the Finkenberg roof tile. A special solar fluid flows through the collectors and absorbs the thermal energy from the direct solar radiation and ambient heat.
This combination makes it possible to achieve a high collector temperature after only a short exposure time, and thus an extremely high degree of efficiency.
The bottom part of the roof absorber and the solar fluid circulating inside it always run at approx. 6 - 10 Kelvin below the ambient temperature of the roof. The solar fluid absorbs energy on account of the difference in temperature between the roof and the air in the throughflow. In many cases, this results in a significantly higher temperature than the outdoor temperature.
