Hello. I have a well - just drilled & capped in S.E. AZ. The depth is 340', Static is 242', & the casing is 6". I also have 6 new Schott 240 watt PV modules. After hours of banging my head against the wall, I've decided to buy a Lorentz helical. My question is should I go with a larger pump for reliability? I've been told to just get enough pump, but I was wondering if a more robust pump would last longer. I was looking at the PS1200HR. Any thoughts would be really appreciated.
