Another solar pumping question

[Mike90250]

Don't know what SCS 18-45 pump is.

But a 1/2 hp brushed DC motor is going to be an electrically noisy thing. I'd contact the motor mfg and ask them if direct off PV is acceptable. I don't know if a LCB will be able to handle that power.

Forgot to say, my insolation is 5.3

Hey there,

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 pump would sit in the well at around 27 feet, the top of the reservoir would be at 12 feet from the ground level. I'm thinking of using a SCS 18-45 1/2 HP Submersible Pump. 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?

Thank you in advance for your responses!
