Abstract
A photovoltaic module includes at least one solar cell, an encapsulant encapsulating the at least one solar cell, a frontsheet juxtaposed with the encapsulant, and backsheet juxtaposed with the encapsulant. The frontsheet includes a glass layer, a polymer layer attached to the glass layer, and an adhesive layer attaching the polymer layer to the glass layer. The backsheet includes a single-layer, moisture-resistant, fire-retardant membrane.
Claims20
A photovoltaic module, comprising:
- at least one solar cell;
- an encapsulant encapsulating the at least one solar cell,
- wherein a thickness of the encapsulant is 0.5 mm to 1.8 mm;
- and
- a frontsheet adjacent to the encapsulant,
- wherein the frontsheet includes
- a glass layer,
- wherein a thickness of the glass layer is 2.5 mm to 4 mm,
- a fluoropolymer layer,
- wherein a thickness of the fluoropolymer layer is 0.01 mm to 0.5 mm,
- an adhesive layer adhering the glass layer directly to the fluoropolymer layer,
- wherein a thickness of the adhesive layer is 50 micrometers to 700 micrometers, and
- wherein the glass layer of the frontsheet is adjacent to the encapsulant encapsulating the at least one solar cell,
- wherein the photovoltaic module is configured to be installed on a roof deck, and wherein, when the photovoltaic module is installed on the roof deck, the fluoropolymer layer is an outermost layer opposite the roof deck.
