Also if these are not load bearing beams ( they have been almost cut throughto allow the pipe going through), make the gap wider and put some isolation around the pipe. But only if the pipe is the case of the water problem

Ah I see now there is double thread 😶‍🌫️

Nice to see another project of you. I'll post my chicken coop project in near future as well

Good question on the low power of motors. Most of the low cost pumps have often DC brushed motors which do not need a controller to steer but uses a brush. Once there is not enough power (in the morning and evening) I think there will be a point where the power will be too low to overcome the torque and the motor stops. The centrifugal pump can still rotate easily compared to other types so I would expect the startup current will be low as well. Panels will deliver a constant voltage while the current will drop when light conditions are dropping. I think the simplest is to search for these aQuarium pumps (24/7 performance) on 12v but I doubt many cars/trucks have built in fishtanks ^^)

Glad to be of help. I think you can get away with a 12v pump as most panels of this power range are made for 12/24v. I suggest very simple centrifugal submergable pump with a bit of filtering around it and direct connection to panel. No inverter or battery, that would be way overkill in my opinion.

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
