BIO-SOLAR PUMPING SYSTEM
Please have a look at the PDF.

Solution

This system is a hybrid of biogas production system and solar system to harness energy. 

Here, the solar array is a panel of solar cells which uses SOLAR ENERGY to run the motor which in turn pumps the water from deep down the well.

The biogas plant uses the bio-waste to produce methane which is fed to internal combustion engine, and is then connected to motor to pump water to field.

The solar array will work fine during bright sunny day, and the methane will act as a BACK UP power supply to it, basically a hybrid system to meet the farmers needs at low cost.
