Project: Prototype construction of a solar heating system for rural regions
Planner: Michael Grausam
Completion: March 2011
Location: Ain Lkhil, Morocco
Project on behalf of GIZ and in cooperation with AUI (Al Akhawain University Ifrane) and HTW Berlin.
The aim of the project was to develop a low-tech solar collector for rural regions. The solar collector uses solar radiation to heat the indoor air to a comfortable level.
A first prototype was installed in an existing school in Ain Lkhil, in the middle Atlas Mountains at around 1200 m above sea level. In winter, the temperature drops to below freezing. Snow falls every year, covering the landscape with a white blanket for one to two weeks. At the same time, there is a high level of solar radiation.
The roof has been doubled. The interior air is ventilated in the air space of the roof construction, which is closed off at the top by a transparent protective layer, thus generating air temperatures of up to 40°C at the outlet of the collector with an outside air temperature of just 6-10°C. This makes it possible to heat even the most remote areas. This makes it possible to heat indoor spaces to a comfortable level even in remote regions.
