a design is described for solar panel that allows for modular installation and efficient removal of panels irrespective of the panel &# 39 ; s relative location in an array arrangement . a system is provided that includes a plurality of modular panels . these panels are rimmed by frames featuring one or more exterior - facing , grooved channels . a first channel — which may be used to mount the panel , and which replaces traditional railing installation systems — and a second channel that is configured to allow movement of one or more panel splices used to secure the panels together . integrated electrical connection interfaces are provided on opposite side surfaces of the frames to couple with the electrical connection interfaces of adjacent panels to establish an electrical path between them . a spacer component may be inserted between panels to provide access to the electrical connection interfaces ; support and rigidity to the joined panels ; a grounding path between the panels ; and , when combined with the panel splices , to align the panels to prevent damage to the electrical connection interfaces .
