Claim 8:
9. A method for producing water from air comprising:
receiving, by a controller of a water generation system, an operational parameter, the operational parameter comprising: a water production amount, solar radiation received by the water generation system, a power state of the water generation system, a relative humidity input to the water generation system, a relative humidity output from the water generation system, or a combination thereof;
determining a loading operational setpoint based on the operational parameter;
flowing a process gas through the solar thermal unit in a process flow path through a first hygroscopic composite during a loading cycle at the loading operational setpoint; wherein the first hygroscopic composite captures water vapor from the process gas upon flowing therethrough;
determining an equilibrated water content of the first hygroscopic composite based on the operational parameter;
transitioning from the loading cycle to an unloading cycle if the equilibrated water content of the first hygroscopic composite is above a predetermined threshold;
flowing a working gas through the first hygroscopic composite during the unloading cycle; wherein the working gas accumulates heat and water vapor from the first hygroscopic composite upon flowing therethrough; and
condensing water vapor from the working gas to produce water during the unloading cycle.
