TRACKED MEGAWATT PV PLANTS: OPERATION RESULTS 2008 IN GERMANY AND SPAIN

摘要

The paper presents the operation results of 5 dual-axis tracked PV plants located in Germany and Spain for 2008. Different tracking principles are implemented in the both German plants. One plant exactly follows the astronomical sun path, whereas the other tries to find the maximum irradiance also at cloudy conditions. The Spanish plants generally follow the sun path. The annual irradiation in 2008 nearly corresponds to the long time average in both countries. There is no clear difference in the final yield of the German plants (approximately 1260 kWh/kW); some results indicate a larger influence of the used modules. The final yields of the Spanish PV plants exceed those of the German plants by nearly 78% which is in agreement with the different irradiance and temperature conditions.
