Claim Text:
1. A solar thermal collector comprising: a first layer comprising polymer and configured to allow sunlight to pass therethrough; a second layer comprising polymer and configured to absorb thermal energy from sunlight; a permeable core disposed between the first and second layers whereby a cavity is maintained between the first and second layers that allows fluid flow between the first and second layers; an inlet for allowing a heat transfer fluid to enter the solar thermal collector and flow through the permeable core within the cavity and in direct contact with the second layer, whereby thermal energy is transferrable from the permeable core and the second layer to the heat transfer fluid; and an outlet for allowing the heat transfer fluid to exit the solar thermal collector; wherein the second layer includes edges sealed to edges of the first layer to thereby form an impermeable and/or bag like structure that surrounds the permeable core.
