I would recommend using a Grundfos SQ 120 or 240 volt AC pump on a timer.
Because you mention using a conventional pump, I assume that there's AC
power available?
The SQ line is very efficient and has no surge at start up. And it's a
lot less expensive than the
SQF line of pumps.

Hi Jeremy,
PV-direct pumps operate at variable speeds depending on the amount of sunlight
and time of day, so a GPM figure is not very helpful in sizing the pump. It's
useful info if the water source will not produce more GPM, since you don't want
to over-pump the source, but it's not enough info to do proper design.
What are you pumping out of? Well, pond, spring box?
How many gallons per day (GPD) do you need delivered, on average? GPD is a much
more useful figure for sizing PV-direct pumps.
Is that "600 ft" of head measured from the standing water level to the top of
the storage tank, as just elevation change and not distance?
A 600 foot-deep well might actually have a standing water level at 300-400 ft.
Even if the pump is set at 600 ft, it only takes energy to lift water from its
standing level, so your head figure would be inaccurate if that is the case.
If it's a well, what is the diameter of the well casing?
What are the peak sun-hours at the site during the darkest time of year that
the water is needed?
There are lots of other questions to ask, but these should help a lot.

Hi all,
Any recommendations for a low flow, high lift pump, PV direct pump.
1 GPM @ 600 ft of head. Maybe a conventional pump on a timer?
