ResumoDifferent small scale solar systems are useful devices in areas with a high amount of solar irradiation for providing hospitals with additional energy where the conventional energy supply is insufficient. Particularly for specialised devices like water pumps, medical sterilizers, water distillation and emergency lighting systems, the energy demand can be covered through solar energy. In the upper east district in Ghana, the district hospital in Bawku was renovated during a project between 1987 and 1990. The advantage of having between 4.7 to 6.4 kWh/m2 of solar irradiation per day in Bawku, meant that solar systems were able to be installed and tested during the project. A solar steam autoclave for sterilizing surgical instruments, two photovoltaic systems as emergency lighting systems and a solar flat plate collector with a 180 1 storage were installed and tested. The washing machine as a main hot water consumer was substituted by a solar washing system, where the water for the machine is heated by solar vacuum tube collectors. A recommendation was made for further substitution of solar energy plants.
