Description:
The training laboratory system should be designed as an educational equipment for studying photoelectric energy conversion.
The construction of the bench consists of a control unit, two solar modules (with single-crystal and multi-crystal solar panels) and a lighthead.

The control unit consists of a housing with the following equipment installed:

• Power supply units, electronic circuit boards, load resistors, front panel and an integrated desktop tabletop

The schemes of the solar panel, load connection and measurement means are depicted on the control unit front panel.
The following equipment should also be located on the front panel:

•  mains switch
•  functional switches
•  lighters with halogen lamps (4 pcs.)
•  digital indicators

The solar modules should be movable frames made of steel section. Each unit has two solar panels mounted on it. The angulation of the panels could be adjusted from 0 to 90 degrees at fixed 5 degree intervals. The temperature of each panel is controlled by a digital thermometer.
The lighthead is a movable frame made of steel section with 8 (2 groups of 4 pieces) halogen lamps, each 0.5 W power. Each group has it’s own power switch.
The laboratory system set should include software and methodical guidelines.

Experiments to be provided:

1.   The study of the laboratory bench.
2.   The study of the construction and operation principle of photoelectric converters.
3.   The study of the characteristics of the solar panels of different types.
4.   Parallel connection of solar panels.
5.   Series connection of solar panels, bypass diodes.
6.   The characteristics of solar panels depending on radiation intensity, incidence angle and temperature.
