Photovoltaic plants can be grid-connected or supply a single load (stand alone plant). In this last case an accumu-lator battery is present to provide power in case of a lack of solar radiation. The following figure shows a block diagram of a stand alone photovoltaic plant. Photovoltaic array Single module String Charge regulator DC load AC ...
