Nowadays, a comprehensive understanding of photovoltaics is necessary for a variety of professions in the fields of renewable energies. For the relevant studies and courses of education, leXsolar-PV Professional offers the optimal tools for practical courses. The spectrum of experiments reaches from the physical fundamentals of photovoltaics, to the analysis of the components of PV-Systems, up to the design of complex PV-Systems on a laboratory scale. The experiments are designed to be equally employed for training of sales representatives, for apprenticeship, in-service training of technicians and PV-installers, as well as form basic education of engineers. leXsolar-PV Professional offers experiments for both electrical engineering and photovoltaics. But the main focus is on laboratory experiments on photovoltaic systems. Due to the modular setup, the very detailed specific characteristics of single components can be analyzed, such as the switching threshold of series or shunt regulators. Because of the integrated manual mode, the included MPP tracker enables a descriptive understanding of the really important principle of the MPP tracking. With the help of the PWM regulator the principle of pulse width modulated charging can be demonstrated. In addition, an inverter displays the generation of alternating current out of a solar panel current. The product is completed through a variety of different electrical consumers such as a super bright LED or a light bulb, which can be used to compare their efficiency. A radio, which can be powered to the solar panel, helps to increase the attentiveness of students.
