Patent ID: 7677242

Claim:
A solar-panel unit comprising: a support structure having a bottom cross bar and a top cross bar, the top cross bar being parallel to and in a raised position with respect to the bottom cross bar; and a plurality of solar panels including at least a first solar panel and a second solar panel, each solar panel delimited by a plane surface of incidence of solar radiation and having a first end rotatably coupled to the bottom cross bar and a second end rotatably mounted to the top cross bar to be rotatable about an inclined rotation axis forming a substantially constant angle smaller than 90° with a respect to a horizontal plane, each of the plurality of solar panels positioned alongside at least one other laterally adjacent solar panel and having the plane surface parallel to each other, all of the rotation axes for the solar panels in the plurality being on substantially the same plane; and a first adjustment device and a second adjustment device for each solar panel wherein each solar panel includes first and second ends, the first adjustment device rotatably coupling the first end to the support structure, the second adjustment device rotatably coupling the second end to the support structure, at least one of said first and second adjustment devices having slidably coupled members, providing adjustment within a distance range, at least one of the first and second ends coupled to the corresponding one of the first and second adjustment devices and selectively fixable to the adjustment device within the distance range to form an angle of positioning different from zero between the corresponding inclined rotation axis and the surface of incidence.
