- solar modules and solar generators (series and parallel-connection of modules , the occurrence of HOT-SPOTS, protection equipment, characteristic curves of the ideal an real solar modules, cells types)
- structure of photovoltaic-supplied energy systems, power coupling (pulsed and clocked inverter , dimensioning of the coupling elements between the inverter and power-supply, choice of pulse frequency)
- measurement- and counter-arrangement for solar systems,
- economic aspects in the use of solar systems tax and legal issues in solar systems, requirements of network operators, content and objectives of the german Renewable Energies Act, photovoltaic from the perspective of the network operator
3. Wind energy
- Construction of wind turbines (efficiency, rotor blade adjustment, optimum operating point, mechanical transmission system, mechanical and electrical oscillations)
- generator and inverter concepts (direct network connection, line-commutated converters coupling, pulse voltage inverter high-pole synchronous generators)
4. Hydraulic energy
