Photovoltaic – Trainingsystem for vocational and advanced training

plus module stand. Using a dimmable spotlightwhich is vertically as well as horizontally movablefixed to an outrigger, seasonal daily curves caneasily be simulated.

Additional options are the change of slope angleand the simulation of the influence of irradiation andtemperature on the characteristic curve of a PV-module.

To ensure a reproducibility of measurements andnot to depend on the weather, a PV-modulesimulator was developed, which exactly simulatesthe behaviour of a PV-module. The short circuitcurrent can be adjusted.

What a pupil ortrainee can workout on his own inpractice orientedlabscale experim-ents, is trans-ferable to realsystems withoutproblems.

The Solar branchis one of theimportant growthmarket of thef u r t u r e .

Development

Application

Construction

In cooperation with the ISET - Institut für SolareEnergieversorgungstechnik e. V. (now: Frauen-hofer Institut für Windenergie und Energiesystem-technik IWES) in Kassel the company IKS Photo-voltaik developed the Photovoltaic-TrainingsystemSolartrainer profi.

The PV-Trainingsystem is suited for the instructionschools, vocational training Schools, training

centres, evening classes and universities.Supported learning objectives can be electrical andsystem engineering , construction, mode ofoperation, connecting and installation of PV-plants.It can be used both to the supplementarydemonstration of lessons and courses as well as forthe use in practical training

The system consists of individual plugin units eachwith components for different experimentalarrangements. The plugin units are put in therackside and connected according to the demand.The conception of the system allows indoor andoutdoor experimentsIndoor experiments are easily possible amongothers because of the system included PV-module

Experiments

The basic principles of photovoltaics considering the influence ofdifferent parameters can also be imparted as the application of directconnected small systems, the mains behaviour of stand alonesystems and the especially for craftsmen very important line poweredoperation mode:

Characteristic curve of a diode, respectively adiode series

Characteristic curve of a solar module (I/U)and (U/P), MPP

Characteristic curve of a solar module (I/U)depending on irradiation

Characteristic curve of a solar module (I/U)depending on temperature

Power output of a solar module dependingOn the angle of incidence of the light

Simulation: Power output of a solar moduldepending on the position of the sun (morningto evening / winter- and summertime)
