The exhaustion of fossil-fuel resources and the decision not to construct new nuclear power plants introduces an even more challenging situation for Italy with respect to other industrialized countries.

There is thus an urgent and growing need for energy produced with components that will not wear out over time.

Photovoltaic energy

Current photovoltaic technology will certainly not fully meet our planet’s current demand for energy, however it represents and will increasingly represent an indispensable factor provided it is used in the best possible manner, adopting high-level designs and manufacturing methods. An element that has contributed towards the spread of photovoltaic technology is an exchange with the distribution network.

This ingenious solution allows us to eliminate the enormous problem of the accumulation of energy needed for periods in which solar radiation or wind intensity are not sufficient to generate enough energy for the users’ needs.
An equally important advantage is that the surplus of energy produced is not wasted and is recovered in the very large ‘lung’ provided by the distribution network. 

Photovoltaic transformers 

Electrical current generated by photovoltaic cells does not have the characteristics that will allow it to interconnect with the network.

From the form of DC voltage, through appropriate devices (inverters) it is therefore converted into alternating voltage with a network frequency at 50-60 Hz.

Sometimes, however, between the network and the inverter outlet it is appropriate to insert an isolation transformer that will block any elements of disturbance for the network and will be able to galvanically isolate the network itself from the entire system.
