Sorry but my statement is true. You do not even know the difference between AC and DC. The power level you are talking about is commercial and industrial size. You have no business even trying this yourself. In the USA it would take preofessional engineers and experienced electricians to pull this off.
So nor Sir I will not help you to kill yourself. You can do that all by yourself. I will not be responsible. I would also suggest the moderators pull the plug on this thread so they cannot be held responsible for any information you might receive here...
Here is what happens to people like you playing with electricity. It is not a pretty site.

You need to understand that some of the things discussed here can be dangerous to a Do It Yourselfer. There is a fine line between helping someone and giving someone that is not qualified enough information to hurt themself. Sunking is very knowledgeble, VERY knowledgeble, he just doesn't have a very good bedside manner. That comes from helping the shear number of noobs that stop by this forum. Don't take it personally, there are plenty of people here willing to help.

Thanks for reply. For solar based solution, sunlight hour would be sufficient with mentioned flow rate. I think no need to have a staorage in battery bank or overhead tank.Leave a comment:

Guys i suggest you quit trying to help this guy. He does not know the difference between AC and DC.Leave a comment:

will it be single phase? i wish to learn more about it..Leave a comment:

Does this pump run only during the irrigation hours?
Is it possible to utilize an overhead storage scheme to spread out the pump time a bit?Leave a comment:

I'd say DC direct is going to be your best bet. You will need a custom controller to match the VI curve of the panels to the motor and enable starting at low light levels; it will likely be expensive at those voltage/power ratings. 40kW is probably about right, so you'd be looking at around $80,000 worth of panels with mounting structure.Leave a comment:

I have a tube well installed on my land delivering approx 1.25 Cusec (101.94 cubic meters per hour). The water depth is 80 ft' and is lifted through KSB turbine that is driven by 25HP 3Phase motor. The diameter of delivery pipe is 6 Inches. The water is used to irrigate the crops spread over approx 50 acres.As far as 2nd option is considered, a gentleman doing a solar PV business in our area advised me 35KW Inverter (DC to AC) and 40KW of solar panel. To support his solution he gave the reason of this over sized setup as the conversion losses of inverter and starting toque of motor.Leave a comment:

Need to shift Agriculture Water Pump to Solar Power
I have a tube well installed on my land delivering approx 1.25 Cusec (101.94 cubic meters per hour). The water depth is 80 ft' and is lifted through KSB turbine that is driven by 25HP 3Phase motor. The diameter of delivery pipe is 6 Inches. The water is used to irrigate the crops spread over approx 50 acres.
From last few years, energy shortfall is growing and one of the biggest issues in our country. So finally we decided to go for alternate solution. I have made extensive research from local market, domain experts and obviously internet, my initial finding are
(1) Replace that motor with a 25HP DC motor and then connect it with a PV array
(2) Use solar panel array with a heavy inverter that may support and run the existing motor efficiently.
(3) Use 3 Phase submersible AC motor along with a heavy inverter and array of solar panel
(4) Buy off the shelf Solar Water Pump (Like Lorrentz) and install it.
(5) Is there any other option? Please advice.
I am unable to decide which solution will be suitable for me. The solution should be cost effective and long-lasting.
While working on point-1, I found 25 HP used DC motor from market. According to supplier, the motor takes 400V for Field and 310V for armature. Apart from this he does not know anything and unable to help me . I need to know what additional hardware and how many solar panels I need to run that motor. In which combination the solar panels will be installed and of what capacity.
As far as 2nd option is considered, a gentleman doing a solar PV business in our area advised me 35KW Inverter (DC to AC) and 40KW of solar panel. To support his solution he gave the reason of this over sized setup as the conversion losses of inverter and starting toque of motor.
Please advise which one of above is more suitable for me and why.
Option 3 and 4 is not viable for me so far because it will need another bore.
