A solar energy collector arrangement is comprised of a plurality of parallely arranged strip-like mirrors, preferably made of aluminum with a silver layer on a concavely curved surface and solar cells being arranged on the rear convexly curved surface, upon which the mirror next to the first mentioned one concentrates solar radiation. These mirror strips are suspended by means of cable inbetween two bars so as to change the orientation of them vis-a-vis the sun; the bars, in turn, are preferably pivotably connected to a telescopic mast, there being additionally guide cable for gathering the individual mirrors. The entire arrangement can be pulled together by pulling all mirrors in juxtaposed position and pivoting the transverse bars against the telescopic mast.

Solar energy collector

A solar panel is constructed from plural parabolic-cylindrical mirrors arranged side by side, and each mirror has three functions. Its concave ground focusses solar energy, its convex rear carries a strip-like solar cell being thereby disposed close to the focal line of the adjacent mirror, while the rest of the rear surface and possibly also the ground surface dissipates thermal energy.
