Tree-shaped ground area efficient device for preparation of large areas for photovoltaic-, solar-, and solar thermal collectors, has slim columns with cast-in steel pipe which forms base frame for stability
摘要
<p>The tree-shaped ground area efficient device has a slim column (1) with cast-in steel pipe which forms the base frame for the stability. A structure of a frame is formed lying outside at the upper end part of the column. A steel plate is mounted on the frame. A rotating assembly is mounted on the steel plate for the function of the solar tracking.</p>
