NOVELTY - Support assembly (112) for supporting at least one photovoltaic module (102) on a support surface, comprises: a body portion including a base portion for accommodating at least one ballast (114), and comprising a polymer; and integrated grounding means configured to provide integrated grounding between adjacent photovoltaic modules. The support assembly is configured to bridge multiple rows of photovoltaic modules without being directly secured to any other support assembly, and is structurally configured to accommodate photovoltaic modules in both portrait and landscape orientations.    USE - The support assembly is useful in a mounting system for supporting photovoltaic modules on a support surface (claimed) including building rooftops or roofing membrane.    ADVANTAGE - The support assembly: is capable of supporting a wide variety of different sizes of photovoltaic modules; exhibits improved weatherability; does not require the electrical grounding, and eliminates the use of a cotter pin, hence saves installation time and money; utilizes the integral wire clips, which obviate the need for separate wire clips; prevents the roof membrane from being damaged or punctured; can be easily removed at the end of its life cycle for recycling purpose; is environmentally friendly, universal and rustproof; and is efficient in withstanding wind loads.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a mounting system (110) for supporting photovoltaic modules on a support surface, comprising: many photovoltaic modules disposed in an array that includes many rows of the photovoltaic modules; and many separate support assemblies supporting and orienting the photovoltaic modules in the array, where each of the support assemblies comprises the body portion, and the integrated grounding means, and the support assemblies are configured to bridge two of the rows of the photovoltaic modules without being directly secured to any other of the support assemblies.    DESCRIPTION OF DRAWING(S) - The figure shows a perspective view of an array.
