How many panels ? ( to run 230 volt sprinkler pump 30 minutes a day?)

    Has anyone worked it out yet ?

    I'm dying to hear the answer ! With or without battery storage and how
    the 2 methods compare in cost.

    Ron wrote the single best post in this thread, answering the OP's
    question directly and properly mentioned better solutions. If you
    could learn to think and write half as well then you might not be the
    butt of so many jokes.
    George has said a *lot*, beginning with a display of his confusion
    about the difference between watts and amps, and his resultant
    ludicrous recommendation of 154 panels. Only after everybody made fun
    of him did he eventually settle on 10.3 panels, almost matching Ron's
    estimate... many days and dozens of posts later. If George were
    selling deeezines, he'd need to post his calculations on Usenet every
    time to see if they were correct, or even in the ballpark.
    Fortunately, nobody with an Internet connection would be dumb enough
    to hire him.

    ....only for those who don't have the experience to know about readily
    available alternatives. For example, I'll be installing a 10gpm setup
    for a friend soon. Array will be ~350W (depends on what modules are
    available at best price) See curves for 11SQF-2 here Daily output will
    be in the 3000 to 4500 gallon range (some 15 times the OP's volume
    needs). So while you're busying yourself hilariously trying to fit
    every application into your GIGO spreadsheet no matter how
    inappropriately, normal people choose the best and most cost-effective
    hardware to suit their application.
    Only a true ghinius could start off with such a mind-bogglingly
    moronic assumption. The rest of your calculations are equally idiotic.
    Oh I see, this exercise was a transparent attempt to excuse your
    original 154 panel recommendation. Lame. I hope you wasted lots of
    time on it.

    Your first and only response to embarrassment is always to try to
    distract attention from your mistakes by writing ever more ridiculous
    BS. Since your preference is to pretend that you're something you're
    not, why not pretend to be a normal person, and simply own up to your

    "The first rule of holes: When you're in one, stop digging."

    Just the usual GIGO resulting from spreadsheet abuse.

    Classic ghinius self-busting expirteeze.
    Ron quoted you correctly - "There is no speculation involved. If you
    know the daily load, which we do (122.55Ah), the battery is sized to
    meet this load."

    So how can there be a "Different number of Ahs"?

    Yes, but only for those who are doing the calculations for some
    purpose other than trying to cover up blunders.
    True, your lack of experience shines more brightly with every post.

    That does not explain your making multiple battery-size
    recommendations. Which one do you believe is correct? Or is this like
    your "20 liters per week/fortnight" fuel consumption, or your
    "150/200A, 150/8.5 Ohm" rheostat, or your "7/15" year-old system,
    where readers are supposed to imagine that all versions of your
    stories must somehow be correct?

    Who is "we"? Do you imagine that your cargo cult has more than a
    single member?
