Patent ID: 8643323

Claim:
A photovoltaic system for generating an output voltage that is uninfluenced by varying irradiation, the photovoltaic system comprising: an electrically rechargeable photovoltaic source having a first connector and a second connector; a voltage adding arrangement that includes a first connector, a second connector, a first route having a voltage source, and a second route as a voltage source bypass, wherein the first and second routes extend between said first connector and said second connector of the voltage adding arrangement; wherein the voltage adding arrangement is connected in series with the photovoltaic source and said first and second routes are alternately activateable, wherein the voltage adding arrangement includes a charger device connected to the voltage source of the first route, the charger device having a first input terminal and a second input terminal, and is connected to a charger switch for using output voltage from the photovoltaic source to electrically charge the voltage source.
