stand-alone systems


These systems are mainly used for rural homes, houses in the country, relay stations, water pumps, etc, that are not on the conventional grid or where connection is not economically viable. The most specific element in a stand-alone system is the batteries which make it possible to achieve supply parameters similar to those of the conventional grid.

Systems are correctly sized to ensure they work satisfactorily for the user regardless of the season of the year or the weather conditions in the area where they are to be installed. To achieve this balance, the right technical combination of photovoltaic energy and mini wind turbines, generator and thermal power is sometimes necessary.

You must tell us your actual requirements and we will meet your needs by providing the right equipment, applying for subsidies, and installing and maintaining the equipment.


These facilities consist basically of solar panels, a solar regulator, batteries specially designed for use in solar facilities, plus a converter able to supply electricity in the same conditions as the grid, i.e. 220 V. These systems, correctly sized by a specialised company, guarantee a totally autonomous electricity supply.

The solar field produces the electricity required to make the stand-alone solar system work. It consists of an array of photovoltaic solar modules conveniently interconnected to adapt to the rated voltage.

If on-site wind conditions are suitable, they can be combined with a wind turbine.

The battery charge controller is an electronic device designed to prevent batteries from overcharging or discharging in order to extend their useful life. Depending on their quality, the performance of solar panels can be increased by 30%.

The battery stores the electricity generated by the engine/wind/solar field for use when necessary.

The inverter is the electronic device that converts the DC electricity stored in the batteries (12, 24 or 48 V) into AC (220 V), making it possible to run both the electrical appliances of a conventional home and any other AC appliances.


Power supply for places that have no access to the grid.
