Note:
In this paper a new experimental apparatus for the measurement of the performance of solar collectors is presented. The test rig and the instrumentation are described. Two types of heating liquid collectors are installed: a flat-plate and an evacuated tube collector. Measurements of efficiency and pressure drop can be performed for both the collectors. The method of calculation indicated by the standard EN 12975-2 is adopted to perform tests and to determine the efficiency curve. Much attention is paid to the experimental uncertainty of the measurements, being a decisive aspect in the comparison of the performance of different collectors. The present experimental setup allows to perform measurements of the global and diffuse solar radiation on the horizontal plane and on the collector.
