SOLAR POWERED WATER PURIFICATION SYSTEM

This ingenious system functions without the support of any external energy source. It is composed of a battery bench or a photovoltaic field, a bi-directional, inverters system and finally a diesel generator which consumes gasoline economically. During the day, solar energy captured by the photo-voltaic panels, powers the purification installation and charges the batteries. When the sun disappears, the batteries continue to run the installation during the night. The batteries are designed for a 1 day period of autonomy. If the sky is over cast for more than 1 day, the system would eventually commute to the diesel generator.
