A solar Water pump is a normal pump with an electric motor. To generate the electricity needed for the engine on site, a photo voltaic panel converts the sun’s energy into a continuous electric current (12 or 24V in general) that can be stored in a solar battery park. Since photo voltaic panels generate a continuous electric current, a solar water pumps equipped with a DC motor must be used.

Small-scale pumping irrigation is one of the most interesting uses of solar energy since the maximum intensity of solar radiation is generally the period of the most important pumping water requirements. On the other hand this energy is available just at the point of use.

A solar pump can also be used in a motor home or a house to put the water stored in a pressure tank and make it available for domestic use .

• A photo voltaic pump comes in two ways depending on whether it works with or without a battery
• The first uses a solar battery to store the electricity produced by the panels, it allows a night use or in bad sunlight conditions and eliminates the problems of adaptation between solar panels and solar water pumps.
• The pumping rate can be on demand, when users need it, or allow regular pumping throughout the day.
• The pump without battery, or “pump with the wire of the sun”, in general, sends the water towards a tank to store it until the moment of its use.
