Solar cell This high sensitivity, monocrystalline silicon device has a light sensitive area of 98 +/-2 cm2. The output under “one sun� conditions is 0.48 V at 3.1 A. The Solar Cell can be connected to motor no. 5005.00 or no. 5015.00, motors with different electrical impedance. In high irradiance situations (e.g. direct sunlight) motor 5005.00 will barely rotate, while 5015.00 will. If a spotlight is used instead the propeller of motor no. 5005.00 will rotate.

Solar measuring instruments Pyranometer 4890.00
This instrument is intended for the measurement of the direct solar irradiance. The output signal is temperature compensated, and each instrument is individually calibrated. The output signal is directly proportional to the global solar irradiance in watt per square meter. An output signal of about 160 millivolts corresponds to an irradiance of 1000 W/m2. All components are weather protected so that the instrument is suitable for mounting outdoors. Size: 10 x 10 x 2.5 cm. Output signal: 0 - 200 mV 4890.10 Pyranometer

Pyrheliometer with digital thermometer
4890.10
This instrument is designed to measure the direct solar irradiance. The detector at the bottom of the collimator tube is a black painted brass cylinder to which a digital thermometer probe has been mounted. Only the direct rays of the sun (and some circumsolar radiation) reaches the detector. The complete user’s guide which is provided explains the pyrheliometer equation. This permits calculation of the solar irradiance from the heating of the brass cylinder. Measurements throughout the day permit the solar constant to be determined. The technique was first used by Pouillet in France in the 1830's and later by John Ericsson in the USA who was able to determine the solar constant with remarkable accuracy. 4890.00 Pyrheliometer with digital thermometer
Hand pyranometer with display This instrument is designed for field measurements of global solar irradiance. It is supplied with a digital display for direct readout of the irradiance in watts per square meter. Two 4 mm safety jack terminals are provided so that the signal can, if required, be used by a remote unit like a datalogger. The device is powered by a 9 volt block battery (provided). 4890.20 Hand pyranometer with display

Heat energy Thermocouple This item can be used to illustrate the phenomenon of thermoelectricity. It consists of a piece of copper wire stretched between two pieces of constantan wire. The copper wire is wound and soldered securely to the constantan wire. If a temperature difference exists between the two junctions, an electrical potential (on the order of millivolts) can be measured between the two pieces of constantan wire. Supplied with 4 mm safety jack connectors and with a 10 mm diameter support rod.

Thermal generator The generator uses a Peltier element with 72 junctions connected in series and mounted on a cooling plates. If a temperature difference exists between the two sides of the element, then a potential difference will be generated (Seebeck effect). On the other hand, if a potential is supplied to the element, at temperature difference will appear between the two sides (Peltier effect). The exposed side of the Peltier element can be readily heated or cooled e.g. using a metal conta5015.00 iner with hot or cold water. An electrical current can then be observed. The presence of this current is easy to show to a group using a small lamp (e.g. 1.5 V, 0.09 A item no. 4250.05) or a low torque motor no. 5015.00. If a voltage is applied to the Peltier element to produce a temperature difference, then it must be no more than 8 V at 5 A.
