An instrumentation and water circulating console is attached to the panel under test via flexible hoses and this displays all of the relevant measured parameters.
Flat Plate Solar Collector unit is designed for internal or external operation. A Flat Plate Solar Collector similar to those used for heating swimming pools or domestic hot water is mounted on an adjustable frame. For internal operation an artificial solar source is available on application as an optional extra.
Experimental Capabilities:
Measuring the efficiency of a Flat Plate Solar Collector
Study of the variation of incident energy on the collector and collector inclination.
Analysis of the efficiency and heat losses of the collector in use.
With the addition of optional computerised data acquisition the daily variation of incident energy and system performance.
With the optional focussing collector, comparison of the efficiency with a flat plate collector.

The circular plate rotates rapidly, showing that the plate is white, indicating that daylight is synthesized by the above seven colored lights. This is the first attempt to find the law of color synthesis. also called "seven color plate"". Newton's instrument for the description of daylight. The round plate is divided into seven sections, and each of them is painted with seven colors: red, orange, yellow, green, cyan, indigo and violet.
