FOCUSING SOLAR ENERGY COLLECTOR

FOCUSING SOLAR ENERGY COLLECTOR

A focusing solar energy collector on a mobile frame. Specially designed for educational use, the apparatus shows the principles, advantages and limits of this method of capturing solar energy.

It is a highly-polished stainless steel parabolic reflector, supported on trunnion bearings on a turntable. By adjusting the horizontal and vertical position of the reflector, students focus solar energy onto an energy collector. The energy collector is a copper cylinder with an embedded thermocouple that measures the cylinder temperature.

To enable students to compare different concentration ratios, IMPACT supply four different sizes of energy collector. Also supplied is a removable transparent cover for the collector, so students can study the properties of shielded and unshielded collectors.

Attached to the reflector carrier is a solarimeter (pyranometer) that measures the incident solar radiation. An extra thermocouple measures ambient temperature for reference.

The cylinder thermocouple, the solarimeter and the ambient temperature thermocouple connect to a Display Unit. The Instrumentation Unit shows ambient temperature, collector temperature and solar intensity from the solarimeter. It also has a socket for connection to IMPACT’s optional VDAS®.

The equipment works with IMPACT’s Versatile Data Acquisition System (VDAS-B, not included). IMPACT’s VDAS® allows accurate real-time data capture, monitoring, display, calculation and charting of all the important readings on a computer.
