  • the invention relates to a scaffold for solar collectors, with which a plurality of solar collectors can be combined to form a planar unit.
  • Solar collectors are usually manufactured in small dimensions (up to approx. I x 2m) for production and transport reasons. Since the solar collectors are often not designed for mechanical loads, they need an additional scaffold, the corresponding stability in mechanical actions, such as. from wind, lends.
  • solar collectors can be tracked, so that the solar radiation always impinges as vertically as possible on the solar panels.
  • the cost of the tracking mechanics can be significantly reduced since several solar collectors require only one common mechanism instead of one individual unit.
