    How does a Photovoltaic System work?

    On the roof, solar panels transform sunlight into DC current.
    An Uninterruptible Power Supply (UPS) converts this DC energy into AC 230V/50Hz.
    It can be either totally used for domestic equipment, partially used and the rest sold to the Utility, or totally sold.
    Preventing this costly installation from damages due to lightning is strongly recommended.
