Solar photovoltaic array tracker having axially offset panel sections
A solar array row includes a first panel section including a first frame tube and a first photovoltaic panel connected to the first torque tube and a second panel section including a second frame tube and a second photovoltaic panel connected to the second torque tube. The row further includes a drive engaged with the first frame tube and a cabling system including a cable connecting the first panel section to the second panel section. The cable translates rotational force on the first frame tube to the second frame tube such that, when the drive is actuated, the first frame tube rotates about a first rotational axis and the second frame tube rotates about a second rotational axis offset from the first rotational axis.
1 . A solar array row comprising:
a first panel section including a first frame tube and a first photovoltaic panel connected to the first frame tube;
a second panel section including a second frame tube and a second photovoltaic panel connected to the second frame tube;
a drive engaged with the first frame tube; and
a cabling system including a cable connecting the first panel section to the second panel section, the cable translating rotational force on the first frame tube to the second frame tube such that, when the drive is actuated, the first frame tube rotates about a first rotational axis and the second frame tube rotates about a second rotational axis offset from the first rotational axis.
2 . The solar array row of claim 1 , wherein the first panel section further includes a table connected to the first frame tube, the first photovoltaic panel being attached to the table.
3 . The solar array row of claim 1 further comprising a support column and a purlin pivotably connected to the support column and attached to the first frame tube.
4 . The solar array row of claim 1 further comprising:
a joint assembly including a universal joint connecting the first panel section to the second panel section, the joint assembly translating rotational force on the first frame tube to the second frame tube such that, when the drive is actuated, the first frame tube rotates about the first rotational axis and the second frame tube rotates about the second rotational axis.
5 . A solar array row comprising:
a support column;
a solar panel;
a mounting arm pivotably connected to the support column and rotatable about a rotational axis of the solar array row, the mounting arm comprising:
a first section; and
a second section extending parallel to and offset from the first section, wherein the first section supports the solar panel and the rotational axis extends through the second section;
a first panel section including a first frame tube, wherein the solar panel is connected to the first frame tube;
a second panel section including a second frame tube and an additional solar panel connected to the second frame tube;
a drive engaged with the first frame tube; and
a cabling system including a cable connecting the first panel section to the second panel section, the cable translating rotational force on the first frame tube to the second frame tube such that, when the drive is actuated, the first frame tube rotates about the rotational axis and the second frame tube rotates about a different rotational axis offset from the rotational axis.
6 . The solar array row of claim 5 , wherein the mounting arm further comprises an oblique section connecting the first section to the second section, the oblique section being obliquely oriented to the first section and the second section.
7 . The solar array row of claim 5 , wherein the second section is positioned above the first section when the solar array row is in a flat orientation.
8 . The solar array row of claim 5 further comprising:
a joint assembly including a universal joint connecting the first panel section to the second panel section, the joint assembly translating rotational force on the first frame tube to the second frame tube such that, when the drive is actuated, the first frame tube rotates about the rotational axis and the second frame tube rotates about the different rotational axis.
9 . The solar array row of claim 8 , wherein the mounting arm comprises a purlin pivotably connected to the support column and attached to the first frame tube.
