In recent years, the possibility to combine photovoltaics (PV) and solar thermal collectors into one hybrid module (PVT-module) has been increasingly investigated. PVT-modules produce thermal and electrical energy at the same time. As the efficiency of a photovoltaic module decreases with temperature, the temperature of the heat transfer media is often(More)

In this paper the different factors influencing the low light performance of solar cells and modules are analyzed and combined to simulate the low light performance of different solar module technologies. The parameters for the diverse technologies were extracted from module databases and the simulation was performed on the basis of high resolution weather(More)
This paper summarizes the climatic and national preconditions for photovoltaic energy production in Chile and Bolivia. Furthermore, design process, realization and monitoring of three different photovoltaic energy supply systems for professional schools in Chile and Bolivia are presented: Two 3-phase grid integrated systems and a 1-phase island system.
