Water collection profile of 2 days from prototype P3 showing (a) 1900 mL/panel (After 1:30 the measurement system could not measure since the water collector was full) and (b) 700 mL/panel water generation with their respective recorded surface temperature, TS, and dew point temperature, DP. It is observed that the temperature difference between the PV module surface (TS) and the dew point temperature (DP) should be above 5 °C to achieve higher water collection.
