Description

The RE10 Advanced Photovoltaic Energy system provides students with a self-contained modular system, covering the physical fundamentals of photovoltaics, the analysis of the components of PV-Systems, and the ability to design complex PV-Systems on a laboratory scale. 

The system includes experiments to allow students to determine the fundamental properties of solar cells; analysing electrical characteristics of solar cells; measuring and describing the influence of environmental conditions on solar cell parameters. 

Due to its modular design, very detailed specific characteristics of single components can be analysed, including switching threshold of series or shunt regulators, MPP tracking, PWM regulator and power generation.
