What is an Off-Grid System?
It is an electric power system that is not connected to the public power grid. The main source of power could be supplied by a fossil or a renewable energy and produce electricity for autonomous energy consumers.
Benefits of the Off-Grid System
This system provides the necessary electrical power in remote areas where it isnot possible to establish connection to a public grid or it is a very costly option.
Thus, allows access to electrical power enables the satisfaction of basic needs such as:
  • Water pumping and purification
  • Food refrigeration
  • Lighting
  • Rural electrification
  • Another advantage of this system relies on non-existent costs of raw materials needed for energy production,in this case, the sun.
    Despite an initial higher investment, when compared to conventional fossil-fueled generators, the off-grid system becomes more economical in long term, as fossil fuel prices have been growing in recent decades, with the promise of an irreversible continuous escalation.
    Another benefit of the off-grid photovoltaic systems is related to the increasing demand for such equipment on a global level, leading to a decrease in its price.
    These advantages will be even more noticeable in places where solar radiation is higher, such as Africa and Latin America.
    Where is the real value of the PV Off-Grid Systems?
    This kind of systems has a big potential in remote areas, because it enables the supply of energy to some equipment directly connected to basic needs, such as:
  • Isolated lighting (indoor / outdoor)
  • Water purification (electrolysis)
  • Food refrigeration
  • Street lighting
  • Water pumping (for drinking, irrigation, sanitation, etc.)
  • Telecommunications (towers)
