Improved in situ performance testing of line-concentrating solar collectors: Comprehensive uncertainty analysis for the selection of measurement instrumentation

One year of high-precision operational data including measurement uncertainties from a large-scale solar thermal collector array with flat plate collectors, located in Graz, Austria

“…The uncertainty of the data logger is not included in the sensor uncertainties. If data logger uncertainties were to be added by users of this dataset, it is recommended to set them in the range of ±0.10% - 0.15% of the measured value (uniform distribution), as these values have been used for similar setups [19] .…”

Efficient Gathering, Storing, Distributing and Validation of Data

“…Zirkel-Hofer et al [6] An article discussing the selection and installation of measurement devices based on uncertainty examination of different sensors (focusing on concentrating collectors).…”

“…The ambient temperature is also a crucial measurement, as it allows for estimating heat losses of collectors [4][5][6], storages [16], and pipes [16]. Please note that multiple sensors might be needed if the temperature is different at different places of interest (e.g., collector arrays in the field versus pipes inside the control room).…”

On-site parabolic-trough collector characterization in solar district heating plant under quasi-dynamic conditions

“…The efficiency testing conditions for thermal performance test under quasi-dynamic conditions are referred to the international standard ISO 9806 [4] new revision, made in 2018, which consider the large-size PTC. In some references from Fraunhoher [5,6] the in-situ methodology was presented, using dynamic method (DT). In a previous study [7], a large-size PTC array has been tested at the Plataforma Solar de Almeria (PSA) using a collector installed in East-West orientation and studying particularly the goodness of the quasi-dynamic (QDT) methodology.…”
