There are two basic tracking types: uniaxial tracking-the solar module is movable on one axle only. This type
of tracking is performed in two versions: seasonable tracking and the daily tracking.
In case of the biaxial tracking the modules are pivoted horizontally and vertically. They track the sun with the
help of a sophisticated mechanical system so that the solar module is always perpendicular to the incident light.
By the use of tracking the energy balance of a solar module is significantly enhanced, for example, daily
uniaxial tracking can generate approximately 20% more energy. In contrast, the energy expenditure for the
tracking motors is just about 0.2% of the total generated energy of the system.
(1) Dependence of the solar cell power on the illuminance.
(2) Dependence of the short-circuit current and the open-circuit voltage on the illuminance.
(3) Dependence of the power on the illuminance with a given load.
(4) Determination of the efficiency of a energy conversion (This experiment uses the solar motor to convert
electrical energy into mechanical energy. This is carried out by rolling up a weight on the drive shaft and therefore
performing lifting work).
