    Abstract: A method for operating a photovoltaic system provides, with the turning off of the otherwise adjusted regulation to the maximum power point MPP, to make a selective mismatching at the inverter, in order to cause a battery current, which is added to the system current. As a result, an additional energy source to maintain a minimum feed power is achieved during a rapidly changing cloud pattern.

    Abstract: In a method for forecasting shadowing of a photovoltaic (PV) system due to cloud formation or movement, part of the firmament is imaged with fisheye optics onto the input optics of a digital camera. Pixel groups associated with luminous intensity ranges are formed. The spatial arrangement of the groups is analyzed to forecast shadowing of a photovoltaic system. A line extending from the PV system to the sun is formed and is continuously tracked. A reference line located inside a region around the line is formed. Passage of clouds across a reference line is analyzed. The result of the analysis is used to increase the electric power from the PV system to a minimum value through supply of additional backup energy or to reduce the electric power consumption by disconnecting users to ensure that key users do not experience a drop in supplied power below a minimum value.

    Abstract: A photovoltaic system includes an inverter, a photovoltaic generator with a plurality of serially connected photovoltaic modules, said photovoltaic generator connected to the inverter by an electrical supply line, a controllable fuse interconnected in the electrical supply line between the inverter and the photovoltaic generator and having a signal input, and a voltage-dependent resistor connected between the signal input of the controllable fuse and the electrical supply line and generating a control signal which triggers the controllable fuse responsive to the control signal and interrupts the electrical supply line. The controllable fuse can be used to disconnect the electrical connection of the photovoltaic system to the inverter when a switch short-circuiting one or more modules of the photovoltaic generator malfunctions. The arrangement permits operation of photovoltaic system at an operating voltage of close to 1000 V, thereby allowing use of thinner cables.

    Abstract: A photovoltaic system having a plurality of photovoltaic modules producing electric energy and method for operating such photovoltaic system are disclosed. With the method, the photovoltaic modules are connected to a first DC motor having a motor shaft, and a generator shaft of a three-phase generator is coupled to the motor shaft. The three-phase generator can be connected to a power grid. The motor shaft of a second DC motor can be connected to the generator shaft, with only one of the two DC motors being initially driven with the electric energy produced by the photovoltaic modules. The electric energy is subsequently divided among both the first and the second DC motor. This process significantly shortens the startup process of the photovoltaic system compared to conventional systems.
