Wind screen for one or more photovoltaic arrays and method thereof. For example, a wind screen for one or more photovoltaic arrays includes a screen foundation including a concrete block, and one or more perforation blocks on the concrete block. In another example, the wind screen is configured to cover at least a first side of each array of the one or more photovoltaic arrays.

The invention relates to a method for operating a linearly concentrating solar power plant (1), in which a heat transfer medium flows through a pipeline loop (47) having at least one receiver, the heat transfer medium having a flow velocity which is such that the flow in the pipeline loop (47) is turbulent, at least part of the heat transfer medium, upon exit from the pipeline loop (47), being extracted and recirculated into the pipeline loop (47). Furthermore, the invention relates to a linearly concentrating solar power plant with at least one pipeline loop (47) having at least one receiver in which a heat transfer medium flowing through the pipeline loop (47) is heated by irradiating solar energy, a mixing device (27) being comprised, in which at least part of the heat transfer medium flowing through the pipeline loop (47) is mixed with heat transfer medium to be delivered.
