ABSTRACT: T-Solar Global is the biggest PV electricity producer in Spain. At the end of 2008 T-Solar has an installed power of 143 MW in 28 large ground mounted systems all over Spain. The module technology of these plants is crystalline silicon from different suppliers. The majority of the systems are static devices and only 2.4 % of the power is installed with trackers. The grid connected systems are permanently remote monitored in a centralized control center located in Madrid. This monitoring provides a continuous follow up of the system performance and a real time failure control. The operation results of the 28 systems during one full year will be presented. PV Trackers will be compared with the results obtained on static systems of similar technology and location. Also the superior behavior of an a-Si plant against c-Si plants is shown. T-Solar’s experience proves that ground mounted PV systems can be efficiently planned and executed in a short time and demonstrates that additional investment on real time monitoring systems can be recovered in a short period of time. The operation experience also provides clues for further improvement of large ground mounted PV systems.
Keywords: Large grid-connected PV system, Performance, a-Si.
