A mounting device (10) is disclosed having a one-piece body (11). A slot (20) extends into this body (11), and is defined by a slot base (22) and a pair of spaced slot sidewalls (24a, 24b) that each extend from the slot base (22). The slot sidewalls (24a, 24b) are disposed in non-parallel relation to each other.

A panel for installing a solar battery module according to an embodiment of the present invention comprises: a first connection portion, which protrudes upwards from one widthwise end of a panel; a second connection portion, which protrudes upwards from the other widthwise end of the panel, and which is fitted to a first connection portion of an adjacent panel in the upward/downward direction; a pair of coupling protrusions bent upwards inside the first connection portion and inside the second connection portion; and a seating portion formed between the coupling protrusions, solar battery modules being installed on the seating portion, wherein the coupling protrusions are bent in the direction in which the solar battery modules are provided, such that the solar battery modules can be pressurized and fixed.

Building integrated photovoltaic (BIPV) systems provide for solar panel arrays that can be aesthetically pleasing and appear seamless to an observer. BIPV systems can be incorporated as part of roof surfaces as built into the structure of the roof, flush or forming a substantively uniform plane with roof panels or other panels mimicking a solar panel appearance. Pans supporting BIPV solar panels can be coupled by standing seams, in both lateral and longitudinal directions, to other photovoltaic-supporting pans or pans supporting non-photovoltaic structures, having both functional and aesthetic advantages. In some configurations, the appearance of BIPV systems can be particularly aesthetically pleasing and generally seamless to an observer.
