The present invention relates to a method for controlling a tracker control unit and, therefore, the tracker device of a solar module of a solar power plant, wherein the tracker device comprises a control unit, an actuator element and a support means for supporting the solar module, comprising the steps of detecting a particular event, interrupting power supply to the control unit of the tracker device for a predetermined time period in reaction to the detection of the particular event, resuming power supply after the predetermined time period and in reaction to the resumed power supply actuating the support means by the actuator element to move the support means into a predetermined position.

Control of solar tracker device

The invention relates to a photovoltaic concentrator module comprising at least one lens and at least one photovoltaic cell, further comprising a distance adjustment means configured to adjust the distance between the at least one lens and the at least one photovoltaic cell. Using the distance adjustment means, the cell and the lens can be kept at a desired distance, e.g., the focal distance. The distance adjustment means can be a pressure varying means. The invention further relates to a photovoltaic concentrator array comprising a plurality of photovoltaic concentrator modules and to a method for improving the energy conversion efficiency of a photovoltaic concentrator module.
