Abstract

A solar panel roof surface effectively uses solar panels supported by an open roof support substructure having a series of parallel hollow support beams. These hollow beams support the solar panels on a top surface and accommodate drainage along the beams. The solar panels are secured to an upper surface of the hollow support beams and in combination therewith define a closed sloped roof surface. The series of solar panels are positioned on the beams to define elongate segments of abutting panels. The abutting panels include a sealing arrangement between panels to allow flow of water along the length of the elongate segments. The hollow support beams include a top surface with a central securing slot positioned between panel segments and panel segment support surfaces either side of said securing slot for supporting edges of the solar panels. Fasteners engage the securing slot and the upper edge of the panels to secure the panels to the upper surface of the support beams.

Claims

1. A solar panel roof surface comprising

a roof support substructure having a series of parallel hollow support beams extending downwardly from a roof peak to a roof edge;

a series of solar panels secured to and cooperating with said series of parallel hollow support beams to collectively define a closed sloped roof surface;

said series of solar panels being positioned and supported to define elongate segments of abutting panels where each elongate segment includes a plurality of abutting panels with said elongate segment being one panel wide and supported by adjacent hollow support beams; and

wherein said abutting panels include a water resistant sealing arrangement between panels whereby water on said panels flows along the length of said elongate segments and across abutting panels to said roof edge; and

wherein

said series of hollow support beams include a top surface including a central upwardly opening securing slot positioned between said elongate segments and panel segment support surfaces on said top surface either side of said securing slot supporting edges of said solar panels and at least one drainage channel in said top surface and extending the length of the support beam for draining of water received in said channel to said roof edge; and

a series of fasteners received in said upwardly opening securing slot that engage said slot and cooperate with an upper flanged member to draw said upper flanged member downward pressing said panels against said top surface of said elongate support beams with sufficient pressure to secure said panels to said support beams.

2. A solar panel roof surface as claimed in claim 1 wherein said top surface of each hollow support beam includes two shallow elongate drainage channels positioned either side of said securing slot with each drainage channel being located beneath an edge of the panels forming the elongate segment supported by the respective hollow support beam.

3. A solar panel roof surface as claimed in claim 2 wherein each drainage channel is of a depth less than half the depth of said central securing slot.

4. A solar panel roof surface as claimed in claim 3 wherein each hollow support beam includes two elongate gasket receiving slots parallel to and either side of said central receiving slot and located between said two shallow elongate drainage channels;

and wherein each elongate gasket receiving slot includes a gasket that engages and forms a seal with the panels supported by the respective hollow support beam.

5. A solar panel roof surface as claimed in claim 2 wherein each panel includes a frame having an inwardly directed lower flange that engages and forms said seal with the respective gasket with each lower flange overlapping with one of said drainage channels and extending partially into said securing channels of said respective hollow support beams.

6. A solar panel roof surface as claimed in claim 5 wherein each panel frame and the lower flanges thereof define an inwardly extending bottom peripheral flange and drain holes are provided in said bottom peripheral flange adjacent corners of said panels;

and wherein said drainage holes are located above said drainage channels.

7. A solar panel roof surface as claimed in claim 6 providing a roof structure above an interior space of a building wherein said solar panels each include a light transmitting bottom surface and said panels allow transmission of approximately 5% of available light through said panels to illuminate said interior space of said building.
