Summary
The International Energy Agency's Small Solar Power Systems (IEA/SSPS) thermo-electric power plant in Almeria, Spain, consists of a distributed collector system (DCS) with three fields and a central receiver system (CRS). During the period of September 1983 to August 1984, the DCS-ACUREX field produced a daily average of 1.13 kWh/m2 thermal energy from an average direct irradiation onto a field aperture of 4.48 kWh/m2 and the DCS-MAN field 1.04 kWh/m2 from 5.91 kWh/m2 irradiated energy. In the Spring of 1984, an improved MAN field was put into operation and showed a considerable improvement compared to the original field. It produced 1.88 kWh/m2 thermal energy from 6.96 kWh/m2 daily mean beam irradiation. The CRS plant was proved to be capable of producing twice as much thermal energy per m2 reflector area as the ACUREX field, and it is pointed out that for further development of high temperature applications it has greater opportunities than DCS fields. For solar thermo-electrical power generation, it is necessary to develop more compact thermo-electrical power conversion systems. Of existing engines, Stirling units show potential for adaptation to CRS plants.
