PV Systems: brief description
Nextel Service offers leader solutions in PV systems with or without stockage. On grid and off grid solutions, from few kWs to hundred kWs systems thanks to all made in Italy technologies
On grid systems
In the PV systems photo-voltaic modules produce energy as direct current when they are hit by sunlight.
The inverter transforms the direct current from PV modules into alternate current which can be used in your home or in your company, reducing or eliminating the demand of energy from Public Network.
In some countries it is possible to sell the energy produced by PV modules but not used in his own home.
Off grid systems
Off grid PV systems are always made by PV modules which, during the day, produce energy transformed in alternate current by the inverter.
But in this case, PV system is not connected to Public Network. The user’s energy needs can therefore be met by the PV system itself and with the help, for example, of a Gen Set or of a energy storage system.
Energy storage sytems are convenient?
Energy Storage System
The storage batteries allow you to store energy to be reused later (usually the excess energy produced by the PV system during the day) for example during the evening.
The storage system can be convenient but a careful analysis of consumption is needed

Which PV System?
Which is the right size for my PV system? Better monocristalline or polycristalline modules? Energy storage system is needed? Can I be totally free from energy Public Network?
There are not standard answers, every situation must be analyzed and studied: it is necessary to know the available surface for PV modules, which is the type of surface. It is necessary to know user’s consumptions and future needs.
