leXsolar-PV Professional

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 for basic education of engineers.
