g'day jim,

dunno surely there has to be wiring to get power from solar collector to
pump and soemwhere in the middle a battery or 2 to store the generated power
needed?

would mean buying a 12 volt (if that is the voltage of choice) pump easily
bought from most pond suppliers or a boat shop, you won't need huge pump, as
you don't want say more than trickling water for effect.

will solar itself work? that depend on whether you can face the pv cells
south in your case up there in the north, then how much sun the collector
can actually recieve through those sunny days? target at least 8 hours i
would guess. storing the power is an issue to look at but that is what will
be needed, it would be a miniature stand alone solar system surely or how
else would the pump have continual aon your demand power ie.,. in the app'
12 hours of each day that is dark, then deduct those cloudy and rainy days
over hee app' 1/3 of the days of the year, not to mention your long winter,
but i guess winter need not count. then pump may come with built in
battery?? always the week point of any system. might do better with little
wind generator?

anyhow keep us informed, i would simply us ac power it will be such little
draw to make negligable effect on power usage, yes more involved to set up
but once done you can turn your pump on any time night or day and know it
will work. still only need small pump.

we pump rain water for wash machine through 1/2" boat bilge pump through
1/2" hose at around 700 lt/hour can get pump to around 1k/lt+ per hour
capacity, that pump been going for 3 years now cost around $50AUD.
