Abstract: Method of forecasting heat output of a solar collector. First, heat output for a plurality of solar collectors is simulated, located at respectively different geographic locations but having the same solar collector settings as the solar collector to be forecasted. The simulation is performed by calculating a dataset of theoretical heat outputs for the plurality of solar collectors, based on acquired related weather data. From the calculated dataset a function is adjusted, the function defining the theoretical heat output of any solar collector related to its geographic location, e.g. latitude, solar Direct Normal Irradiation, DNI, and collector settings, e.g. operation temperature, and forecasting the heat output of the solar collector based on the adjusted function. When traditional methods for estimating heat output require substantial amounts of measurements and processing capacity, the proposed method may instead enable an efficient and appropriate method of producing precise estimations of heat output.

Abstract: The logistics arrangement comprises an arm adapted to be pivotably attached to a logistics stand. The arm comprises a support member adapted to carry an object, when the arm is substantially horizontally directed in a storage position, and a pivoting means adapted to pivotably attach the arm to the logistics stand, such that the arm is enabled to pivot between the storage position and a standby position where the arm is substantially vertically directed. The arm also comprises a stop member adapted to together with the logistics stand hold the arm in a storage position. The support member is connected with the stop member and the pivoting means, and the arm is configured to be forced into the standby position by an upwardly directed lift-movement of the another located object, during unload of the lower located object form the logistics stand. The invention also relates to a logistics stand comprising a plurality of logistics arrangements, a logistics system comprising a freight container and at least one logistics stand, and a method for unloading objects from a logistics stand.

Abstract: An arrangement for manufacturing a reflector for a PTC from a rectangular reflective structure. The arrangement comprises a tensioning device configured to tension a reflector portion of the rectangular reflective structure, such that a surface of the tensioned reflector portion acquires a curvature perpendicular to the tensioned reflector portion's longitudinal propagation, along the tensioned reflector portion's longitudinal propagation. The arrangement further comprises a fixating device configured to fixate the surface's curvature, such that the tensioned reflector portion remains tensioned. The tensioning device is configured to tension the reflector portion of the rectangular reflective structure by pre-forming the reflector portion to a pre-curvature, and adjusting the pre-curvature by applying a torque at a longitudinal borderline of the pre-formed portion. Because the reflector will be maintained tensioned by torques only, it will adapt a curvature of a high precision parabola.

Abstract: A method of determining a reflector parameter of a concentrating solar collector's reflector surface. An image is captured of the reflected receiver tube in the reflector surface, with an image capturing device, e.g. a camera, and processed to put together image data related to the reflected receiver tube. Further, the method comprises determining a location of the image capturing device at a capturing time of the captured image, and determining a position on the reflector surface based on the determined location of the image capturing device and the image data. The method comprises also calculating the reflector parameter at the determined position based on the image data. By numeric calculation of reflector parameters, such as slope, defects, e.g. caused by impacts or material imperfections, may be identified at an early stage before installing the solar collectors, which may reduce service needs.
