Abstract

Abstract A solar cell shingle may be made of an array of solar cells on a lower portion of a substantially rectangular shingle substrate made of fiberglass cloth or the like. The solar cells may be encapsulated in flourinated ethylene propylene (FEP) or some other weatherproof translucent or transparent encapsulant to form a combined electrical module and a roof shingle. The interconnected solar cells are connected to connectors at the edge of the substrate through a connection to a common electrical bus or busses. An overlap area is arranged to receive the overlap of a cooperating similar shingle so that the cell portion of the cooperating shingle may overlie the overlap area of the roof shingle. Accordingly the same shingle serves the double function of an ordinary roof shingle which may be applied in the usual way and an array of cooperating solar cells from which electrical energy may be collected.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 53 words
A solar cell shingle comprising a substrate having a cell portion and an adjacent overlap portion, an array of electrically interconnected solar cells mounted on said cell portion and connected to connectors on said shingle, whereby a like shingle may be arranged in overlapping relation on said overlap portion leaving said cells exposed.
Claim 2
Dependent Claim 53 words
A solar cell shingle comprising a substrate having a cell portion and an adjacent overlap portion, an array of electrically interconnected solar cells mounted on said cell portion and connected to connectors on said shingle, whereby a like shingle may be arranged in overlapping relation on said overlap portion leaving said cells exposed.
Claim 3
Dependent Claim 17 words
A shingle as claimed in claim 1, said connectors comprising a male connector and a female connector.
Claim 4
Dependent Claim 37 words
A shingle as claimed in claim 1, said connectors comprising a male connector on one side edge of the shingle and a female connector on the other side edge of the shingle for interconnection to like shingles.
Claim 5
Dependent Claim 24 words
A shingle as claimed in claim 1, said connections leading to connector pads at the top edge of the overlap portion of said shingle.
Claim 6
Dependent Claim 24 words
The shingle as claimed in claim 4, and in combination therewith a connector strip having a channel and means for contacting said connector pads.
Claim 7
Dependent Claim 36 words
A solar cell shingle comprising a roofing material, an array of solar cells mounted on a first portion of said shingle, and a second portion of said shingle for receiving the overlap of a similar shingle.
Claim 8
Dependent Claim 36 words
A solar cell shingle comprising a roofing material, an array of solar cells mounted on a first portion of said shingle, and a second portion of said shingle for receiving the overlap of a similar shingle.
