Renewable Energy - Systems & Lab

Solar panels use light energy from the sun to generate electricity through the photovoltaic effect. A typical photovoltaic installation includes an array of panels, an inverter, batteries and wiring.

Pilot plant for the production of bio-ethanol from sugar cane or, optionally, from tubers (sweet sorghum, manioc, potatos, rice or corn). The pilot plant for the production of bio-ethanol from de lorenzo reflects the experiencethat our company has  accumulated in the field of renewable energies.  the plant  allows producing approximately 150 liters of juice starting from 250 kg of sugar cane and then 10 to 15 liters  of alcohol 94/96%.  the production is in four steps  according to the following block diagram and specifications.
on request, it is possible to produce alcohol with tubers (sweet sorghum, manioc, potato, rice and corn) with additional grinders.

Bench top didactic system for the simulation and the theoretical and practical study of the main circuits and components that are used in lightweight electric vehicles: bicycle, scooter and car.

Bench-top educational system for the  simulation  and the theoretical and practical study of the main circuits and components that are used in lightweight electric vehicles.
The simulator  is divided in three sections, relevant, respectively,  to electric bicycles, scootersand cars and it allows learning their operation through light signaling.    By means of a selector it is possible to choose the vehicle that you want to analyze.
