Summary: Water scarcity is a global issue. The Solar-powered Atmospheric Water Collector (SPAWC) is an innovative solution that extracts moisture from the air to provide drinkable water, supplementing other methods like rainwater harvesting and desalination. The SPAWC system, powered by solar energy, provides a decentralized and reliable source of tap water, reducing dependence on traditional method of water extraction that are often insufficient, or contaminated water source. However, collection of atmospheric water is not possible in urban locations, it works more efficiently with the climate and location that has higher humidity, ideal temperature that is less than 20oC, higher fog frequency and higher fog intensity. The prototype’s components include solar panel, mesh net, gutter for collection system and a water storage. The prototype has undergone series of tests to prove its functionality which includes solar panel efficiency test, battery charging and discharging, weather monitoring, and water collector monitoring. Also, it has been evaluated by 30 respondents and the overall average score is 4.45 with a descriptive rating of Very Good which means that the SPAWC has met the requirements for the developed prototype. The solar energy harvesting efficiency peaks at noon. Over 5 hours of battery charging results in a full charge, with the initial voltage at 10:00 AM being 12.43V (indicating a 60% charge) and reaching 12.96V later, indicating a full charge. In a highly humid environment, the device was able to collect 25ml of water.

Water scarcity is a global issue. The Solar-powered Atmospheric Water Collector (SPAWC)
is an innovative solution that extracts moisture from the air to provide drinkable water,
supplementing other methods like rainwater harvesting and desalination. The SPAWC system,
powered by solar energy, provides a decentralized and reliable source of tap water, reducing
dependence on traditional method of water extraction that are often insufficient, or
contaminated water source. However, collection of atmospheric water is not possible in urban
locations, it works more efficiently with the climate and location that has higher humidity,
ideal temperature that is less than 20oC, higher fog frequency and higher fog intensity. The
prototype’s components include solar panel, mesh net, gutter for collection system and a water
storage. The prototype has undergone series of tests to prove its functionality which includes
solar panel efficiency test, battery charging and discharging, weather monitoring, and water
collector monitoring. Also, it has been evaluated by 30 respondents and the overall average
score is 4.45 with a descriptive rating of Very Good which means that the SPAWC has met the
requirements for the developed prototype. The solar energy harvesting efficiency peaks at
noon. Over 5 hours of battery charging results in a full charge, with the initial voltage at 10:00
AM being 12.43V (indicating a 60% charge) and reaching 12.96V later, indicating a full
charge. In a highly humid environment, the device was able to collect 25ml of water.
