As an example case, if you need to pump from the pond nearby, 2m height difference and pump 0,25liter per second. ((0,25 *2 *9,81)/0,35)*1,33 = 18,6W ->20wp panel. I did not take into account the hose size butn0,25liter per second is not a lot. And every meter height difference added will add an extra 10W to the panel

I perhaps can help you with this. I'm working in a company that is helping smallholder farmers over the world to increase their crop yield. We used to start with a small hydropowered waterwheel but moved to solar due to the reach of the sun. I am the technical person that is sourcing pumps, solar panels, inverters etc for irrigation.

So far as I can read your question you don't need a lot of water and also not a lot of pressure. It is quite easy to calculate.

  • Hydraulic power need (W) / efficiencies = electric power requirement (W)-> *1.3 = solar panel (Wp)

  • Hydraulic power = 9,81 * height differencence of water (m) * liter per second you want to pump

  • Efficiencies = centrifugal pumps are approx 35% eff so (hydraulicp/0,35) *1,33= panelsize

  • halve a liter per second is sufficient for halve an acre (2020m2) of crops.

Please if you have more questions I would glad to be of help

Very interesting read. Time to make these sensory excursions open for public to understand the clouds physical existence.

Nice to see / read. The super glue trick is nice to know. I also wanted to mention that the collection of pictures on the bottom is broken when you open them on movim.slrpnk.net

Well, bad for you if it is a crappy option. The company doesn't care for quality as the consumer has no other option. Hurray for Amazon, our everyday feeder. And for those working at Amazon, only one toilet break per week, as there are no other options for work!

Good job @hamtron5000, you need to place the cats somewhere 😁. We also built a cat collector last month. The trick with us was the stovepipe that did not allow combustables nearby so the pathway is very small for the cats
