Ballast systems for securing photovoltaic modules

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.

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.
