Photovoltaic roof and method of making same
First Claim
1. A method of installing a photovoltaic panel structure, said method characterized by the steps of:
- providing a laminate including a photovoltaic device disposed on a front surface of a structural substrate material, said substrate material and photovoltaic device each having a preselected length and width such that the width of the device is less than the width of the substrate material, said device disposed on said substrate so as to define side edges of said substrate which are free of said device, said laminate further including a transparent polymeric layer disposed upon the front surface of said substrate so as to cover said photovoltaic device and at least a portion of said side edges, said laminate being semi-flexible and rolled up into a coil;
cutting strips of laminate off said coil;
reinforcing said strips by bending the side edges thereof to form flanges disposed at an angle to said front surface so as to form a plurality of substantially rigid photovoltaic panels, each panel including a photovoltaic device for providing electrical output in response to incident radiation;
electrically interconnecting said photovoltaic devices on said plurality of panels proximate the rear surface of the substrate material of said panels; and
fastening said panels onto a support substructure such that a sealed panel structure is formed on said support substructure.

Abstract
A roof structure 10 comprises panels 14 and 16 of desired length each having a galvanized steel supportive layer which has side supporting flanges 22 interconnected together to form the roof assembly 10. The mid portion 20 of each panel has a photovoltaic surface made from amorphous semiconductor material which is laminated onto the galvanized steel with a protective plastic transparent polymer coating laminated above the photovoltaic material. The laminated galvanized steel and the photovoltaic layers are rolled into a coil and transported on site where it is unrolled, cut to size having the flanges formed to construct the rigid panels and having the panels assembled together via clips 26 and weather-proof battens 32. The photovoltaic surfaces are connected together via electrical conduit 34 coupled through couplings 88 under the panels and between the frame members 30.

7. A photovoltaic panel assembly characterized by:
-
a plurality of panels, each panel having a thin film photovoltaic material laminated on a front surface of a planar, semi-flexible substrate material that has side edges extending widthwise beyond said photovoltaic material, said photovoltaic material including an electrically conductive lead in electrical communication therewith, said lead passing through an aperture in said substrate and terminating with a connector proximate a rear surface thereof; and each side edge of substrate material being bent to form reinforcing flanges extending substantially perpendicular with respect to said photovoltaic material. - View Dependent Claims (8, 9, 10, 11)
