Abstract

The objective of the present work is to conduct a comparative analysis of fixed and moving flat-plate solar collectors’ performance. An experimental set-up installed on a location in Shtip (Republic of Macedonia), latitude 41o 45’ and longitude 22o 12’, consists of two flat plate solar collectors, the first one with a fixed surface tilted at 30о towards the South, and the other one equipped with dual-axis rotation system. An experimental programme is performed to investigate the effect of the sun tracking system implementation on the collector efficiency. The study also includes development of a 3-D mathematical model of the collectors system and extensive numerical simulation, based on the computational fluid dynamics (CFD) approach. The efficiency of the implemented system was confirmed by experimental verification, showing significant energy efficiency increase, compared to the immobile collector unit. The comparative analysis shows that there is a good agreement between the experimental and numerically predicted results for different running conditions, and the presented modelling approach can be used for further investigations, including more complex problems.
