The system includes at least one module frame containing a module laminate, at least one support structure having support rails, and multiple boltless mounting components. The mounting components attach the module frame to the support rails. The present invention also provides a boltless module mounting system including at least one module having posts and at least one support structure with support rails. The support rails have receiving slots with a receiving hole and two or more slide slots. The posts interlock with the receiving slots.
