Very cool idea. Few potential issues come to mind: - I bet dust would muck up the MOF - Dust would need to be swept off to allow sunlight energy to reach the solar chamber. - Ambient temperature on mars in below the freezing point of water. May not get enough sun to warm the MOF enough to drive off the moisture. EDIT: Found a source saying that water vaporizes during the day because of the reduced pressure - interesting.
