Abstract :

[en] The present work investigates the solar field performance of a pilot system installed at the University of Liège in Belgium. The system includes eight parabolic trough collectors connected in series (66m² in total) and is aimed for small-scale power generation (2kWe) at low-temperature operation (150°C max.). The paper describes the test facility and presents experimental data gathered under various operating conditions. After posttreatment, the measurements are used to calibrate a deterministic model of the solar collectors. This model is used to better estimate the various sources of losses during the solar energy conversion and to investigate potential means of performance improvements. While the collection efficiency recorded experimentally does not exceed 30%, it is shown that an improvement of the tracking could raise this value to 65% and thus meet the design expectations.
