SOLAR DUAL PUMPS:- The solar dual pumps is an innovative pump designed to utilize the power of the sun during the day and act as a normal hand pump when the solar energy is not available, hence assuring uninterrupted water supply for drinking, sanitation, personal hygiene etc. The system consists of a submersible pump which runs on power generated from the photo-voltaic solar cells and is suitable for use on bore-wells with 100 mm (and above) diameter up to 80-90 meters depth. In practice a solar array is installed near the bore-well, a submersible pump powered with DC motor is installed below the hand pump cylinder. The pump is connected to a storage tank and the collected water is dispensed through a stand post. This system can also be used on other water sources such as open wells or tanks.
