Another solar pumping question
I would like to use solar power to pump around 10.000 L of water/day from a well into a reservoir that I could use for gravity fed irrigation via a drip system. Please give me your thoughts on this, I would like to know if it’s doable. I’m a newbie so please bare with me if I ask something outrageous
The specs on the pump:
At 45 volts DC the peak efficiency point is 18 GPM at 45 feet of head..
Max Current: 8.5 Amps
Max Power: 380 Watts
My question is:
Is it possible to run this pump directly from solar panels with an LCB? Would 2 x 250W panels wired in series do the job?

Solar Water Pumping
You can certainly design a system that will do what you want. Just follow the sizing and equipment selection guidelines provided in the Home Power article.
How did you come to those numbers for head and GPM ?
Why does one want to pump from a well to a cistern for irrigation during a drought condition , do you own a producing farm ?
Using 2641 gallons of water a day and attempting to replace it into a cistern in 2.45 hours is wasteful . If you must perform this operation at least extend the amount of time in which you wish it to happen to lessen the power required to do it .
