When the containerized PV and RO water treatment systems are integrated, they create a self - sustainable solution. The electricity generated by the PV system powers the RO water treatment equipment, eliminating the need for an external power source in many cases. This not only reduces operating costs but also makes the system ideal for remote areas where grid connection may be difficult or unreliable. The combined system can be customized to meet different water production requirements, from small - scale applications for a local community or a construction site to large - scale industrial use.
