Master thesis: Yield of Solar Modules under Outdoor Conditions

Advertising institute: IEK-5 - Photovoltaics
Reference number: D077/2014, Electrical engineering, nanostructural engineering


The announced master thesis deals with the analysis of solar module field data.

The capacity of worldwide installed photovoltaic systems exceeds 100GW. To estimate the achievable gain, the energy yield of these systems is predicted before their installation. During operation yield predictions are important to the grid operator and for maintenance of the systems.

Sets of outdoor data of several solar module technologies were provided to us within a cooperation. With these data sets we test a model that corrects the energy yield to standard conditions. Already in this early stage, the model attracts a lot of interest in the respective scientific community. After an irradiance and temperature correction, information is retrieved on performance-reducing degradation mechanisms. This information is difficult to extract under field operation. Besides the changing temperature and irradiance dependencies of the characteristic solar cell parameters, temporal changes in the diode ideality factor and in the resistances can be analyzed.
