There has been a lot of misconceptions / myth created by various stakeholders on this issue

either due to lack of understanding or unknown about latest technological advancement . The

final product what a farmer needs is water irrespective of DC/AC motor in an efficient way

with low life cycle cost.

Understand A Danish company called Grundfos  with its innovative technology  have

submersible and surface pumps which can run on both Solar and Grid power ( single phase and

3 phase.) Infact the same pump can run on both AC grid power and Solar power by just

change of a switch. Regarding reliability one cannot discount nearly 5000 installations across

India since last 7 years with a failure rate of almost nill due to any technical issues. They also

have sales and service network across India and have found that these pumps are running in 9

Indian states.

On converting the  existing AC pumps is not a good viable  idea as the solar panel requirement

would increase drastically, thus making the investment unattractive.

 Sizing  the correct and optimum pumpset along with the control panel according to the crop

pattern , yield of the bore and the water requirement on a scientific basis would not only

reduce the initial cost of the equipment's ( pu
