Solar panels ans water pumps

[chilidog]

I have a few water pounds I want to use water pumps to circulate the water around and I was wanting to use solar to run them. The idea is to run panels
to operate a 50-100w pump. I don't care to use any batteries just to go from inverter to the pump and whatever the hours I get from it per day is what it is. So the
question is what watt panel do I need to run a 50-100 watt pump direct from the panel/inverter?

This has been done, but usually with DC pump motors and a properly matched set of
solar panels. Regular inverters need batteries to stabilize the power, and AC motors
are very intolerant of the varying nature of solar power. Bruce Roe

Simple you cannot do it that way. They do make pump motors to work directly from a panel, but not your motor. Besides it does not take electricity to do what you want, and no one will steal it.

Is the pump DC and what is the voltage range it can run on?

Not certain SE but he mentioned he does not want to use batteries on an Inverter. Sounds like AC pump to me.

Well as you know an AC load will not work directly from a solar panel without an inverter and batteries so I had hoped the OP was talking about a DC pump. If not then end of story.

I haven not purchased anything yet. I was just looking for some ideas with keeping the cost down because I have several water holes I was wanting to do this with.
So looking at an AC system and DC system prices. I did see awhile ago there was an inverter that hook right into the back of a panel and you could get AC power right away.
If i could get say a 50watt DC pump and have 1 panel for it and put in on a float for each pond or I could make and AC system with x amount of panel for x amount of 50-100watt AC
pumps. If there is not an option to stay away from the biggest cost, the batteries then so be it.
The only thing I have on hand is 2- 285w panels and a charge controller (not sure of the amp rating).

Just by reading my own post look like I might have answered my own question with a 50watt DC pump and a 100watt panel.
I'm simply trying to have water circulation in a pond using solar. Any other suggestions are appreciated.

Thanks

I will let you do your own searches and homework. You can do what you want, just not quite the way you thought of. They make DC Pumps to be ran directly from solar panels. Google is your friend in this case. Just search Solar Water Pumps.

They come in two flavors of Ground (surface) and Submersible (well).
