NOVELTY - The system has a rail clamp assembly (30) to clamp a panel rail (10) to a surface. The panel rail is positioned in an opening of sidewalls and clamp portions made to contact the panel rail. A panel clamp assembly (100) that clamps a solar panel (110) to the panel rail, comprises a fastener e.g. nut, extending through apertures of a rail clamp and a base such that flexible tabs contact a head of the fastener and a clamping arm extends in tab opposite direction. The fastener head and the tabs are positioned within a channel of the rail. The arm clamping end secures an edge of the solar panel.    USE - Mounting system e.g. ground and roof mounting system, for mounting a solar panel to a surface of a racking system i.e. ground-mounted solar panel racking system, in residential and commercial applications.    ADVANTAGE - The system includes a deformable portion inserted between the rail clamp portion and the panel clamp and configured to support the clamping arms in a position ready to accept the edge of the solar panel, so that the solar panel can be installed in an easier and efficient manner. The rail clamp assembly allows efficient installation of panel mounting rails without the need for a drill, as the pre-fabricated holes are not required to attach the rails to the mounting systems, so that the versatility of rail configurations can be increased and the rail clamp assembly can be located anywhere along the rail. The rail clamp assembly can be made of stainless steel to prevent corrosion of the assembly. The system includes a base beam tube and the panel rail that are simply slid into place and held securely with the no-drill connector, so that the solar panel angle can be adjusted to desired value to maximize efficiency, thus reducing cost of the mounting system.
