PV

Planning and installation of Eolic and Solar Photovoltaic systems grid-connected.

Our business includes the design, supply and installation of photovoltaic systems on land, on emissions and on roofs including connection to the national grid.
 


WHAT THE SOLAR :
The term photovoltaic is self-explanatory: it is made from the Greek word phos (= light) and V (= unit of measurement of electromotive force). It is therefore of the transformation of light energy into electrical energy.

 
PHOTOVOLTAIC SOLUTIONS, THE TYPE OF PLANT:

All PV systems can be classified into the following categories:

• POWER DIRECT:
the powered equipment is connected directly to the PV module. The great disadvantage of this type of plant is that the connected device does not work in the absence of sunlight (at night).
Applications: small appliances such as radios, small pumps, hand-held calculators, etc.
 

• OPERATION ALONE:
The photovoltaic module feeds one or more electrical devices.
The 'energy provided by the module, but currently not used, it is used to charge the batteries. When demand increases or when the PV module does not work (at night), it uses the energy stored in the batteries.
Applications: areas not served by the electricity grid and where to install it would not be cost-effective. Example applications include telecommunications as well as the domestic supply of shelters and country cottages.

 

• OPERATION FOR PLACING ON THE WEB:
As the plant-grid solar module powers the electrical equipment connected. The energy not used at the moment is fed into the public grid. For the input of electricity into the grid, as determined by the new net metering, the GSE is to pay the private citizen rimborsandolo economically. In the evening and at night the current can again be taken from the public.
Of course, the manager of a photovoltaic system of this type will be paid by the local power for energy fed into the grid. The energy is environmentally friendly and thanks to the Energy Bill can cover the investment in a relatively short time.
Applications: anywhere that has a standard connection to the public network, such as homes, offices, factories, banks, schools, public buildings, and so on
