BALLAST SYSTEMS FOR SECURING PHOTOVOLTAIC MODULES
A ballast system includes a first ballast tray and a second ballast tray. The first ballast tray has a first side profile including a south leg connected to a north leg. The second ballast tray has a second side profile that is different than the first side profile. A length of the north leg of the second side profile is greater than a length of the south leg of the first side profile, and a height of the north leg of the second side profile is substantially equal to a height of the south leg of the first side profile. The north leg of the second side profile includes a curvature so as to partially curve toward the south leg of the second side profile.
1 . A system comprising:
a ballast tray including:
a base member,
a first leg member extending from a first end of the base member, the first leg member having a first length, and
a second leg member extending from a second end of the base member, the second leg member having a second length that is different than the first length; and
a clamp connectable to one of the first leg member or the second leg member, the clamp including:
a base,
a sidewall extending from the base,
a catch to engage a portion of a frame of a solar panel module that is disposable within the clamp, and
a fastener disposable through the sidewall, the fastener engageable with the solar panel module to secure the solar panel module within the clamp.
2 . The system of claim 1 , wherein at least a portion of the first leg member curves in a direction towards the second leg member.
3 . The system of claim 1 , wherein:
an end of the first leg member is disposed above the base member by a first distance; and
an end of the second leg member is disposed above the base member by a second distance, the second distance being substantially similar to the first distance.
4 . The system of claim 1 , wherein:
the clamp includes a receptacle;
the one of the first leg member or the second leg member includes a channel;
the receptacle is disposable at least partially within the channel; and
a second fastener is disposable through the one of the first leg member or the second leg member and into the receptacle.
5 . The system of claim 1 , wherein the clamp further includes a second catch to engage a second portion of the frame.
6 . The system of claim 1 , wherein the clamp is connectable to the first leg member, further comprising a second clamp connectable to the second leg member.
7 . The system of claim 1 , wherein a ballast is disposable at least partially between the first leg member and the second leg member.
8 . A system comprising:
a ballast tray including:
a base member,
a first leg member connected to a first end of the base member, and
a second leg member connected to a second end of the base member; and
a clamp connectable to the first leg member, the clamp including:
a base having a first side and a second side opposite the first side,
a first catch disposed on the first side, the first catch engageable with a first portion of a solar panel module,
a second catch disposed on the second side, the second catch engageable with a second portion of the solar panel module, and
a fastener engageable with the solar panel module.
9 . The system of claim 8 , further comprising a second clamp connected to the second leg member, the second clamp engageable with a second solar panel module.
10 . The system of claim 8 , further comprising a second ballast tray including a second clamp, wherein the second clamp is engageable with a second solar panel module.
11 . The system of claim 8 , wherein:
the first leg member includes a first profile; and
the second leg member includes a second profile different than the first profile.
12 . The system of claim 8 , wherein:
the first catch is disposed on a sidewall extending from the base; and
the fastener is disposable through the sidewall.
13 . The system of claim 8 , wherein:
the first leg member is disposed in a first direction that is transverse to a second direction of extension of the base member; and
at least a portion of the second leg member is disposed in the first direction.
14 . The system of claim 8 , further comprising a leg member extending from the base, the leg member engageable with the first leg member.
15 . A module clamp comprising:
a base;
a sidewall extending from the base in a first direction;
an aperture disposed through the sidewall;
a first fastener disposable within the aperture of the sidewall;
a catch extending from the base, the catch engageable with a surface of a solar panel module;
a leg extending from the base in a second direction, the leg including an aperture; and
a second fastener disposable within the aperture of the leg, the second fastener to secure the module clamp to a ballast tray.
16 . The module clamp of claim 15 , wherein the catch receives a portion of a frame of the solar panel module.
17 . The module clamp of claim 15 , further comprising a second catch extending from the base.
18 . The module clamp of claim 17 , further comprising a receptacle to receive a portion of the solar panel module, the receptacle disposed between the catch and the second catch.
19 . The module clamp of claim 15 , further comprising a support engageable with the ballast tray.
20 . The module clamp of claim 15 , wherein the second fastener is disposable at least partially through a leg of the ballast tray.
