I just bought the suunydaze pump from amazon and couldn’t be happier. I got the one with the battery backup so I’ll let it charge all day when I’m at work and run it in the evening. The solar panel is pretty small, maybe 8x10, and so is the battery and control center. I mounted the panel on top of my fence and buried the wires leading to the pond. It also has a light that turns on at night mounted under the fountain. I added a finer filter surrounding the pump in the casing. My pond is only 150-200 gallons. I’ve only had it about two weeks so I can’t speak to durability. Edit with link:https://www.amazon.com/gp/product/B01MZ8H9UE/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1
