The solar system is the best generator that can extract energy sources anywhere that has sunlight without the need for any input of materials. With the initial investments, users can benefit from the zero costs of not getting charge for the utility taxes. Which make the solar system is the best cost-efficient asset to fund for charity purposes or to develop the wellbeing of the unfortunate communities. Especially for places such as the Middle East or Africa has a region with the best solar radiance but their societies face water shortages. According to United Nations, more than 40 per cent of the world's population don't have enough supply of freshwater.
The DC motor that is powered by this solar system, which rotated the cylinder at a certain rotational speed inside the rectangular basin, will act as a distiller. This cylinder accelerates water evaporation in the vessel by forming a thin film of water on its outer and inner surface. In further explanation, the machines use electricity to cool the surrounding air in the housing until the air condenses into water that will be collected at the bottom.
