Renewable Energies and Smart Grid » Solar Photovoltaic

A solar photovoltaic system (PV system) is a power system designed to supply usable solar power by means of photovoltaics; it converts sunlight or solar radiation into direct current electricity by using semiconductors. To allow users of different preparation to study this system in its variants, De Lorenzo has developed a large number of trainers that deal with it for basic, medium and high levels. For the basic level, a case has been designed containing the necessary modules to learn the first steps of this technology. For the medium level, there are different types that can satisfy both the technicians (a kit based on sub-modules) and the installers (installation kit or compact mobile structure). For the high level, also here different configurations are proposed such as solar position tracker system, off-grid and on-grid with option a light simulator in order to irradiate the solar panel in indoor places; this latter category is also supplied complete with software for data acquisition and processing. For off-grid and on-grid systems, it is also possible to replace the standard solar panel with a solar tracking panel and monitor its meaningful parameters comparing them with the expected optimal setting according to the actual sun position. Who is more interested with a simulation of solar and thermal panels with the aid of a dedicated software, he can also find here what he needs such as a simulator module. They are dedicated to schools, high schools and first years of university according to the level.
