Solar power water pump.

I wish to build a solar powered water pump. I have in my junk pile a
working 12volt twin shaft motor onto which I will add the pumps,
modified from those you can get as a drill attachment. This will be
connected to a battery, like those from a motorbike (small and
compact). This is so I can make it portable, because where I plan to
use it is lacking in electricty. Now my only concern is he draining of
the battery before the job is completed, so I plan to add a solar
panel to charge the battery while its at rest or in use. Do I need any
circuitry, if so what and where can I find plans or products.

Thanks for any help given.

We need some specs first. How much current will the motor draw under load?
What size battery will you have?
The solar panel needs a power output that can charge the battery in your
required time, and of course provide the proper voltage.
The 'portable' aspect of you setup may suffer a little when the panels start
to get large.

BTW: Those drill attachment pumps are not designed for drinking water just
in case you had that in mind.

Tom

I saw a neat one at the centre for alternative technology in wales (uk) -
it had a couple of large capacitors which stored just enough energy to
drive one stroke of the pump, so that if the sun was low it would sit
there accumulating charge, then do a single stroke, then go back to
waiting. So you could ask them how they built it maybe? (www.cat.org.uk)
It was a push-pull type pump though, not a rotary one.

I was at Wal-Mart the other day, and noticed several different sized solar
panels used to charge car batteries. They were sealed, water, and impact
proof in a frame, and varied in size form about 12 inches by 4 inches, to
about 12 inches by 12 inches. They seemed VERY RUGGED, and were VERY CHEAP,
the most expensive being around $30.00. They also had a led, that turned on
when charging. I really don't know if this will fit the bill, as they seem
to be for Long-Term trickle charging, so someone else more skilled here will
have to tell you if they will be useful for you.
I use one of the smaller panels to trickle charge a small motorcycle
battery between uses on a hovercraft that I own. For that, it keeps the
battery fresh, and ready to use ALL THE TIME.

Not moving potable water, just filling water tanks at an allotment.
Lot easier than a bucket. Will get specs later as my junk has buried
the motor again. But I know it's there. :eek:)

Right heres the specs I know that comes off the motor housing. It was
made in the UK by a company called Smiths Industries. It has a code on
it which is marked as "Code FHM 582/109" And it runs from 12 Volts.
Thats all I can tell you. When I find more I'll let you know. The
battery will be a standard motorbike battery, if that tells you
anything.
