Abstract
Abstract A solar panel comprising at least one solar energy transducer laminated between a transparent vitreous sheet and a second sheet in which the transducer is imbedded in a layer of transparent polymeric material which bonds the sheets together. The polymeric material comprises an acrylic compound. A method of making the aforesaid solar panel in which the acrylic compound is allowed to set in situ is described.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
100 words
A method of manufacturing a solar panel including at least one solar energy transducer laminated between a transparent vitreous sheet and a second sheet, which comprises the steps of effecting said lamination with a fluid medium which comprises an acrylic compound which polymerizes at low temperature without substantial change in volume and polymerizing said fluid medium in situ at a temperature below 60° C. to form a transparent polymeric layer in which said transducer is imbedded and which serves to bond said sheets together, said fluid medium comprising a mixture of methyl methacrylate resin and polyurethane prepolymer as main constituent.
Claim 2
Independent Claim
100 words
A method of manufacturing a solar panel including at least one solar energy transducer laminated between a transparent vitreous sheet and a second sheet, which comprises the steps of effecting said lamination with a fluid medium which comprises an acrylic compound which polymerizes at low temperature without substantial change in volume and polymerizing said fluid medium in situ at a temperature below 60° C. to form a transparent polymeric layer in which said transducer is imbedded and which serves to bond said sheets together, said fluid medium comprising a mixture of methyl methacrylate resin and polyurethane prepolymer as main constituent.
Claim 3
Dependent Claim
27 words
A method as defined in claim 1 wherein the total amount of acrylic compound in said fluid medium is at least 30% by weight of such medium.
Claim 4
Dependent Claim
27 words
A method as defined in claim 1 wherein the total amount of acrylic compound in said fluid medium is at least 90% by weight of such medium.
Claim 5
Dependent Claim
20 words
A method as defined in claim 1 wherein said transducer is held in position between said sheets by spacer means.
Claim 6
Dependent Claim
45 words
A method as defined in claim 1 wherein prior to the utilization of said fluid medium a desired number of transducers is positioned on one of said sheets, the other sheet is assembled thereto, and the margins of the assembly are sealed, leaving a gap.
Claim 7
Dependent Claim
23 words
A method as defined in claim 5 wherein said fluid medium is introduced between said sheets through said gap after tilting the assembly.
Claim 8
Dependent Claim
39 words
A method as defined in claim 6 wherein after the assembly is tilted as aforesaid the sheets are inclined at an angle measured with respect to the horizontal of less than 30° during the introduction of said fluid medium.
Claim 9
Dependent Claim
17 words
A method as defined in claim 1 wherein said transducer is totally encapsulated by said polymeric layer.
Claim 10
Dependent Claim
20 words
A method as defined in claim 1 wherein said vitreous sheet has a primer applied to the bonded surface thereof.
Claim 11
Dependent Claim
66 words
A method as defined in claim 1 wherein said transparent vitreous sheet is made from a soda lime glass having a composition such that its total energy transmittance for solar radiation is greater than that of a similarly dimensioned ordinary soda lime glass which contains ferrous oxide, said glass having a composition which contains iron oxide with substantially all of said iron oxide being ferric oxide.
Claim 12
Dependent Claim
19 words
A method as defined in claim 1 wherein said polymerizing is at a temperature between 20° and 40° C.
Claim 13
Independent Claim
103 words
A method of manufacturing a solar panel including at least one solar energy transducer laminated between a transparent vitreous sheet and a second sheet, which comprises the steps of effecting said lamination with a fluid medium which comprises an acrylic compound which polymerizes at low temperature without substantial change in volume and polymerizing said fluid medium in situ at a temperature below 60° C. to form a transparent polymeric layer in which said transducer is imbedded and which serves to bond said sheets together, said fluid medium being mixed and/or poured in situ in a low pressure environment of 20 to 50 torr.
Claim 14
Independent Claim
