1. A system, comprising:
a plurality photovoltaic modules installed on a roof deck, wherein each of the plurality of photovoltaic modules includes
at least one solar cell, wherein the at least one solar cell includes a first side and a second side opposite the first side,
an encapsulant layer contacting the first side of the at least one solar cell,
a glass layer juxtaposed with the encapsulant layer,
and a encapsulant-backsheet layer contacting the second side of the at least one solar cell,
wherein the encapsulant layer and the encapsulant-backsheet layer encapsulate the at least one solar cell; and
an underlayment layer installed on the roof deck,
wherein the underlayment layer is separate from each of the plurality of photovoltaic modules,
wherein the plurality of photovoltaic modules are over the underlayment layer, and
wherein the system does not include an intervening layer between the encapsulant-backsheet layer and the underlayment layer.
