The main aim of the project is the testing and development of photovoltaic system technology to make it more reliable and to improve the costs, in southern European climatic conditions. One of the tasks in this project was the evaluation of the use of photovoltaic plants in conjunction with hydro-electric power stations in southern Europe. Due to the small quantities of water in the summer months, electricity generation is considerably less in this period. By combining hydro-electric and photo-electric powerstations, one could perhaps achieve a continuous output to the medium voltage network. The photovoltaic plant works directly connected to the 15 kV medium voltage network. Two solar fields orientated solidly to the south with laser grooved buried contact (LGBC) cells from BP solar and MISI cells from the firm of ASE have a total output of 855 KWp. A futher solar field with a rating of 95 KWp, which is also equipped with LGBC cells, follows the sun about one axis. The measurements during the quality control and the acceptance phase showed that the efficiency of the module is within the range stated by the manufacturer. The measurements of the first year of operation gave a total output for the photoelectric plant, including all losses due to high module temperatures, dirt and mismatching, of 888 kW. For a total of investment of 17 million DM, the electricity generation costs are between 0.81 DM/kWh and 1.08 DM/kWh, depending on the writing-off period. Energy amortisation times are about 4.5 years (at the Toledo site). (orig./AKF)
