摘要 |
The invention relates to a method of optimisation of a sun panel of the single-axis-concentrating type of the kind exhibiting a trough-shaped, asymmetrical reflector (1) with a reflecting interior surface serving to reflect incident solar radiation onto an elongate absorber (3) located in the trough, which absorber is arranged between a front (4) and a rear (6) reflector portion. In a first step, with respect to both shape and positioning in relation to a horizontal plane, a cross-sectional profile (7) of the reflector (1) is determined with a longer extent in both the forward and the backward direction in relation to the final reflector. In a second step, a reflector member of a given width is displaced in the forward and the backward direction, respectively, in relation to the reflector profile (7) to a position providing the maximum amount of annual solar irradiation for an intended place of installation.
