A system for the selectable adjustment of an angle of elevation of groups of PV panels or panel arrays, relative to a roof to which the panels are attached, includes a platform, upon or thru the roof. The platform including horizontally secured rails. Also included are a parallel series of lower couplings, each member of the series provided upon the rails, and having a transverse distance between them sufficient to accommodate a PV panel array. Each of the couplings are provided with integral extensions or tabs, each having an aperture within a portion not in engagement with the platform. The system also includes linear support members secured to undersides of the panel arrays to be selectably elevated, each of the support members substantially co-planar with the rails of the parallel series of lower couplings. Struts of fixed lengths are selectably provided between alternates of the lower couplings within each of the series of couplings, in which alternate couplings, not associated with the struts, are rotationally or pivotally secured by extension tabs of each coupling and selectably secured to couplings upon the linear support members of the panel arrays. Also provided are equal length strut pairs of selectable lengths, each strut having an aperture at each end, detachably securable between corresponding lower and upper couplings of each of the series pairs of couplings between the rotational couplings. Selection of a pair of corresponding equal length struts, related to coupling pairs upon the parallel series of couplings and rails, effects an angle of elevation of a PV panel array as a function of the length of the co-equal lengths of the struts within the parallel series of couplings and rails.
