"The design and construction of an autonomous water potabilizer that only uses solar energy as an energy source were developed. Relying on engineering areas such as mechanics, mechatronics, and optics as the main areas for its development. The autonomy was performed through the assembly of an automated control stage for the whole system powered by photovoltaic modules operating; reverse osmosis, and photocatalytic reactor, among others. In addition, during the reactor construction, a method for the CPC collectors manufacture is proposed, which includes the utilization of a 3D printed mold based on a structural styrofoam molding."
