Solar pumps might be cheap but the solar panels are not so cheap. I have my unit working on about 110 watts with two panels but one panel would work during the day light. I would dump about a gallon of Humic acids into the water to seal the pond just to keep it in the pond. If you are wanting to run a pump 24 hours then you better figure on two panels and a battery backup. Depending on where the water is coming from then you might want to consider a gas powered pump just to top it off every other day or so.
