OFF - GRID PV SYSTEMS

Installation process of an off-grid photovoltaic system

To proceed with the installation of an off-grid system you need to download and fill out the Log File of energy consumption of your site and send it to us for evaluation. We will determine your energy consumption footprint / profile based on which your system will be sized. The economic analysis and the economic benefits of the system will follow, and if the final specifications are agreed, we proceed with the installation of the system.

What is the off-grid photovoltaic system

Off-grid photovoltaic system is the system whose output is not fed into the PPC electricity network and therefore there is no financial transaction with the provider. The energy generated is stored in batteries, through which the electricity needs are served.

The off-grid photovoltaic systems are indicated for installation in remote areas that are not connected to the PPC network or are outside the urban plan, but also in cases where the interface with PPC is considered cost unadvisable.

Depending on the site usage (permanent or holiday residence, commercial building) they can fully supply the electricity needed or may need to be combined with a backup power generator when power needs exceed power production. Their compatibility with the PPC network is also not excluded in order to reduce the cost of electricity consumption.

 

The off-grid photovoltaic systems consist of

  • Photovoltaic panels, which absorb solar energy and convert it into electricity.
  • Batteries, which store the generated electricity.
  • A power inverter, which converts the generated direct current into alternating current consumed by electrical appliances.
  • A charge controller, which regulates the voltage and the operating frequency of the system.
  • Net Metering - Go Solar
  • COMMERCIAL SECTOR
  • Enefsys - Save your energy
