A solar panel clamp, comprising:

• first and second opposing clamp portions;
• the first clamp portion comprising a first end and a second end, the first end including a first projection and the second end including a first recess;

• a fastener engageable with the first and second clamp portions;
• the clamp having a loosened configuration in which the first projection is received within the second recess and the second projection is spaced apart from the first recess by a first distance, and
• the clamp further has a tightened configuration in which the first projection is received within the second recess and the second projection is positioned closer to the second recess than said first distance.

A clamp, comprising:

• first and second opposing clamp portions engageable with each other at first and second ends;
• and
• a fastener engaged with the first and second clamp portions;
• the clamp having a loosened configuration in which the first and second clamp portions are connected at the first end and are separated by a distance at the second end;
• the clamp having a tightened configuration in which, at the second end, the first and second clamp portions are positioned closer to each other than the first distance;
• the first and second clamp portions having corresponding projections and recesses disposed at the second end for deforming a captured portion of a roof seam as the clamp is moved from the loosened configuration to the tightened configuration.
