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.
