Abstract
A deflection pad may include a body including two peaks, and a recess in the body between the two peaks, the recess may be sized to accommodate a fastener such that when deployed, the fastener is below a height of the two peaks within the recess. The deflection pad may include arms projecting in a direction generally opposite the two peaks, the arms biased inward towards the recess. The deflection pad may be included in a system that includes a torsion beam and one or more support racks to which multiple PV modules may be attached, where the support are racks attached to the torsion beam. One or more deflection pads may be positioned on the support racks to be below the PV modules.
Claims12
A system comprising:
- a torsion beam;
- a rack to which multiple PV modules may be attached, the rack attached to the torsion beam;
- a first end bracket at a first end of the rack and a second end bracket at a second end of the rack opposite the first end;
- one or more mid brackets spaced along the rack such that the first end bracket, the second end bracket, and the one or more mid brackets cooperatively fixedly couple the multiple PV modules to the rack;
- a first deflection pad on the rack positioned at least between the first end bracket and a first given mid bracket of the one or more mid brackets so as to be underneath a first given PV module of the multiple PV modules held between the first end bracket and the first given mid bracket, the first deflection pad comprising a spring leaf;
- and
- a second deflection pad on the rack positioned at least between the second end bracket and a second given mid bracket of the one or more mid brackets so as to be underneath a second given PV module of the multiple PV modules held between the second end bracket and the second given mid bracket.
A system comprising:
- a torsion beam;
- a first rack to which a PV module may be attached, the first rack attached to the torsion beam;
- a second rack to which the PV module may be attached such that the first and the second rack together fixedly couple the PV module to the torsion beam, the second rack attached to the torsion beam;
- a deflection system coupled to the torsion beam between the first rack and the second rack such that rotation of the torsion beam corresponds to rotation of the deflection system and such that the deflection system is positioned beneath the PV module when the PV module is attached to the first and the second racks, the deflection system comprising:
- a deflection pad;
- and
- a strap coupled to the deflection pad, the strap securing the deflection pad to the torsion beam.
