Abstract
Abstract The invention concerns a photovoltaic generating panel easily adaptable to a roof. The panel is equipped with a peripheral frame formed by the assembly of straight light alloy shapes. The particular form of these shapes makes possible the laying of adjacent panels with overlapping of the edges of the latter.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
280 words
A photovoltaic generating panel of generally quadrangular shape having a multiple number of semiconductor solar cells inside a laminate for immobilizing and protecting said cells and connecting means on the periphery of said laminate partially overlapping several identical panels to assure waterproofing by direct laying of said panels on the frame of a sloping roof, said connecting means comprising: first and second frame pieces fastened on opposite edges of said laminate pointed in the direction of the pitch of the roof and having identical sections including a U-shaped portion fitted side ways on opposite edges of a said laminate, an extension of one side of the branches of said U, and at least one wing perpendicular to said extension having a height less than the thickness of said U-shaped portion, said extension and wing forming at least one sealing groove, said sealing grooves of said first and second pieces pointing in opposite directions; a third frame piece fastened on the bottom edge of said laminate pointed level with the roof and having a section identical to that of said first and second frame pieces, the sealing groove of said third frame piece directed to emerge opposite the exposed face of said panel; and a fourth frame piece fastened on the top edge of said laminate pointed level with the roof and having a section including a U-shaped portion similar to that of said first three framed pieces and at least one sealing wing having a height which is greater than the thickness of said U-shaped portion and less than double the thickness of said U-shaped portion, and said wing being directed to emerge toward the exposed face of the panel.
Claim 2
Dependent Claim
280 words
A photovoltaic generating panel of generally quadrangular shape having a multiple number of semiconductor solar cells inside a laminate for immobilizing and protecting said cells and connecting means on the periphery of said laminate partially overlapping several identical panels to assure waterproofing by direct laying of said panels on the frame of a sloping roof, said connecting means comprising: first and second frame pieces fastened on opposite edges of said laminate pointed in the direction of the pitch of the roof and having identical sections including a U-shaped portion fitted side ways on opposite edges of a said laminate, an extension of one side of the branches of said U, and at least one wing perpendicular to said extension having a height less than the thickness of said U-shaped portion, said extension and wing forming at least one sealing groove, said sealing grooves of said first and second pieces pointing in opposite directions; a third frame piece fastened on the bottom edge of said laminate pointed level with the roof and having a section identical to that of said first and second frame pieces, the sealing groove of said third frame piece directed to emerge opposite the exposed face of said panel; and a fourth frame piece fastened on the top edge of said laminate pointed level with the roof and having a section including a U-shaped portion similar to that of said first three framed pieces and at least one sealing wing having a height which is greater than the thickness of said U-shaped portion and less than double the thickness of said U-shaped portion, and said wing being directed to emerge toward the exposed face of the panel.
Claim 3
Dependent Claim
52 words
The generating panel of claim 1, wherein said four framing pieces are finished at their ends by oblique sections partially intersecting said U-shaped portions and also by straight sections, said third and fourth frame pieces having their straight ends resting on the straight longitudinal section of said first and second frame pieces.
Claim 4
Dependent Claim
70 words
The generating panel according to claim 1, wherein said first, second and third pieces have a section, the shaped portion of which contains two wings thus delimiting two sealing grooves, and in that said fourth piece has a section, the shaped portion of which contains two sealing wings delimiting a fitting recess which is adapted to be coupled with the sealing grooves of said third piece of an adjacent panel.
Claim 5
Dependent Claim
40 words
The generating panel according to claim 1, wherein said fourth piece has a section which also contains an extra wing pointing in the opposite direction of said sealing wing, making possible the fastening of the panel of the roof frame.
Claim 6
Dependent Claim
25 words
The generating panel according to claim 1, wherein each of said four straight pieces forming said frame consists of an aluminum alloy shaped by extrusion.
Claim 7
Dependent Claim
18 words
The generating panel according to claim 1 including a sealing gasket between said U-shaped portions and said laminate.
