TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Components: The base portion comprises: integral wire clips for accommodating at least one wire of the photovoltaic modules; a bottom surface with at least one groove for accommodating at least one respective gasket or piece of a cord stock; and one or drainage channels and at least one weep hole for draining water from the base portion. The body portion further comprises at least one upright support member coupled to the base portion, where the upright support member comprises an integrally formed slot in its one side for receiving an edge of a wind deflector, so as to enable the edge of the wind deflector to be coupled to the support assembly without a fastener. The support assembly further comprises at least one clamp subassembly that is coupled to the body portion, and configured to be coupled to the photovoltaic modules. The clamp subassembly comprises: a pivotal base member with a curved bottom surface; a base member and an upper clamp member coupled to the base member by a fastener; an L-shaped flange portion comprising a flange base portion and an upright portion attached to the flange base portion, where the upright portion comprises an aperture for receiving a fastener for securing one edge of a wind deflector to the support assembly; and at least one component formed from a conductive material, where the components form the integrated grounding means. The clamp subassembly is: rotatably coupled to the body portion of the support assembly; configured to accommodate many different tilt angles of the photovoltaic modules; and detachably coupled to the body portion by a removable pin member, so that the upright portion of the L-shaped flange portion is capable of being disposed near a selected one of opposite sides of a component of the body portion. The clamp subassembly further comprises a bonding clamp member, where a portion of the bonding clamp member is configured to accept the photovoltaic modules to form at least a portion of the integrated grounding means. The bonding clamp member has a structural configuration and a material composition that enables the bonding clamp member to accommodate thermal expansion and contraction of the photovoltaic modules. The upper clamp member comprises spaced apart protrusions extending from its lower surface, where: a gap is formed between the spaced apart protrusions of the upper clamp member; the spaced apart protrusions are configured to prevent the photovoltaic modules from becoming disengaged from the upper clamp member; and the gap between the spaced apart protrusions is configured to accommodate thermal expansion and contraction of photovoltaic modules. The support assembly is in the form of a non-penetrating support device that does not penetrate the support surface. In the mounting system, the clamp subassembly is coupled to a respective body portion of a respective support assembly.
