A survey was conducted to collect information on faults, failures and poor performance from large PV plants a well as residential system like the ones of the »1000-Roofs-Programme«. The reason for a low energy yield in some systems was analysed. Modern modules built for a high voltage show very few failures. In one plant electrical faults affected 0.1 % of(More)
This paper provides an overview of a Spectrum Monitoring Pilot Program within the U.S. Department of Commerce. It provides background, motivation, goals, accomplishments, and plans for future work. We describe the development of a federated Measured Spectrum Occupancy Database (MSOD) architecture that allows organizations to host MSOD instances and(More)
