Skills to be acquired in this module

After successful completion of the module students should be able to:

·         categorize and feature different PV systems

o    PV on-grid,

o    PV off-grid / stand alone,

o    PV-pumping,

o    PV-hybrid
by their setup and by standard quality indicators.

·         explain the operation principles of the listed PV systems

·         explain concepts behind PV system design

·         design a photovoltaic system by Fermi Estimate

·         design a photovoltaic system by a simulation software

·         be aware of the limitation of both design methods

·         discuss energy flow diagrams of PV systems

·         describe in depth involved balance of system components e.g.

o    inverter,

o    charge controllers

o    cabling

o    generator stand

storage battery with a focus on housing (ventilation)
Module contents

This specialization module covers more in-depth topics concerning photovoltaics systems.


The module consists of:


Photovoltaic Systems Lecture (90h workload)

Description and operation of PV System’s balance of system components

o    inverter,

o    charge controllers

o    cabling

o    generator stand

o    storage battery with a focus on housing (ventilation)

Quality indicators for PV Systems and their regional differences

o    PV on-grid,

o    PV off-grid / stand alone,

o    PV-pumping,

o    PV-hybrid

Sizing of PV systems – back of the envelope approach as well as by a simulation software


Photovoltaic Systems Seminar (90h workload)

Within the seminar groups of up to five students select a PV system related research question, work on the solution and present their findings.

In addition, external PV experts are invited to present from their work experience.

An excursion to a PV power plant concludes the lessons learned in the field.
