DEE-53117 Solar Power Systems, 5 cr
Suitable for postgraduate studies.
Students having taken the course are able to provide a general overview on solar energy resources and on technologies to utilise solar energy in power production. Students will obtain a good general understanding on solar photovoltaic (PV) power production technologies. This will include various semiconducting PV materials, generator topologies, power grid interfacing, system installation and operation etc. Students will also achieve a basic knowledge on concentrating PV and solar thermal power production technologies. In particular, student having taken the course are able to explore solar PV power systems operating in various environmental conditions. Both the built environment of the solar PV system and the climatic conditions will be considered. Solar PV systems will include solar PV power plants within the power range from kW up to GW as well as building integrated PV power plants. Also basics understanding on solar PV power plants as electrical systems and their electrical safety and lightning protection will be obtained. Furthermore, students will be able to explain and argue plausibly on the present status and forthcoming development of solar PV market and its role in power production in the future.
