Anyone have any experience in solar water pumps? Am i getting garbage for ~4-600?

Definitely interested in this
Went into this rabbit hole.
Won’t work on my end but interesting
I actually didn't know these were sold as kits, and built my own. 1st thing, you likely don't need that much solar. 2nd you likely don't need that much pump. 3rd, you still need battery housing and housing for that controller. I'm not familiar with that brand tho.
I have a 100w panel, powering a pump that has 100ft head with a car battery in a case pumping water from my pond to anywhere I need it in the not freezing months. It runs for 5 minutes 5 times a day and I NEVER saw the 40 gallon tank less than a centimeter from the top. I should probably do a post on the setup in the spring but I can show you the specifics if you'd like. My setup cost like $300 total
Plan is to power on the barn roof. push is 200ft with 0 elevation gain. 2 ibc from rain out to secondary tanks then do drip off tanks that are infield. My biggest issue is the tower infield has 0 elevation and i would like to build something that wasn’t an eye sore.
How does the roof have 0 elevation gain? Or do you mean where the water is to where it's going is 0 elevatiom gain? If so this pump is way over kill.
I'm struggling to understand your setup based on this message, a simple drawing would help.
There's a picture attached. 2 IBCs stacked at the barn, I need to irrigate a 100ft W by 500ft L area.
You’ve got me thinking:
The barn is ~25ft tall. It will have eves. Why does my storage need to be at the barn? I need pressure more than anything. Why not put 4 ibcs 250ft out then irrigate from there?
The height from the barn will suffice to push the water to the ibcs then I can build my system from there.
1 manifold feeds the entire system. 
Is the horizontal what you need to irrigate? Is there any elevation drop there? If you just put your IBCs at the highest point, you will not need a pump with 275x4 gallons of pressure.
I would recommend putting the IBCs at the barn to top feed them straight from the gutter, otherwise you will need a pump to go from the ground to the ibc tote top. Bonus points if you put them on the north side to block the sun. More points if you both paint them black and wrap them to eliminate algae growth. Both are needed, I see systems with one or the other and the sun still leaks in.
windmills are great and have relatively high efficiency due to the pure mechanical coupling... a staple of dry land well pumps for - well... must be now getting towards centuries
you really need to make a design with up-hill reservoirs though, idk if you've lived with house water systems that rely on pumps instead of filling a cistern, fucking annoying, cannot get a reasonable stable pressure out of them, always flipping off when it's perfect and going back to a trickle, then turning into a jet when you wanted a trickle
Cool find. I built something similar out of industrial parts. Do you have a specific question or just looking for opinions?
Are they atleast the most efficient panels on the market?
