Pumping water using solar

Gman1987

Hi all, is anyone pumping water using solar? If so would ye be able to advise what set ups ye have? Make + size of pump, solar panel etc?

I'm thinking of setting one up if I can. I'm on a scheme that runs on gravity flow but I have no water in three fields that are circa 80 foot above the nearest water trough. Dont know how to put the system together but thinking of purchasing the following:
https://northstarsprayers.ie/12v-diaphram-pumps/northstar-nsq-series-12v-on-demand-diaphragm-pump-7-0-gpm-60-psi-max.html

Plan to run this off a deep cycle battery and 100watt solar panel (I have this and a charge controller already). Questions I would have if anyone could help:
1. Will this pump be suitable? Idea would be that this pulls the water either directly from the Gravity flow water pipe or alternatively from a water trough
2. Should I be using a pressurised cylinder also or would this work pumping direct to trough's and cut in and out even when the lift is 80ft?

If anyone has suggestions on how I can set this up please share.

How far are the fields from the water source?

You could look at a series or solar Archimedes screws to raise the water into a series of canal type structures and then pump from these into the fields on demand.

I believe this is what is used in some third world countries

I am in a similar situation myself except from a deep well. Out farm with no ESB & only used for summer grazing. Solar would be very handy but from research the setup costs seem quite high & the uncertainty of there reliability I am hesitant to go down this root so I am pricing an ESB connection. If it is not too costly then I will go this root.

Its not that far at all, its just 120 metres but about 80ft uphill. The other two fields that dont have water would be about 60ft uphill so I could use the trough at the top field as a reserve to feed the other two fields if needed. Hoping the pump would work.

Not a farmer, and Not sure what your water source is, but if it's a stream you have access to, in certain scenarios an hydraulic ram pump can be an option, powered by the water hammer effect so no need for electricity.

Do you need to run a fencer as well?

I know they had to increase the size of the solar panel on a farm near me, there was about 100 yearlings being watered on it last summer.

I'm on a group scheme that's gravity fed, 3/4 inch pipe down through the farm so no option to install a ram pump.

Any idea what pumps and internal components they use in this set up? Effectively this is what I'm looking to put together but hoping to do it on the cheap.

Sorry I don't know, what is your budget like? I think the basic one is 1200, incl the box.

Will that pump even lift the water 80ft? If it's designed for a sprayer then I'd doubt it.

The issue with all of these on demand 12v pumps are meant for sprayers or camper Vans and are unlikely to pump the water as far or as high as you want.

Maybe if you had an IBC with ball valve located beside lower drinker and used a submersible well pump to pump the water. Most of these don't have built in pressure switches so you would need a separate pressure switch or other means of controlling it.

Would it not be simpler to stick with know technology? A diesel/petrol pump, stick it in a trailer and with big water troughs run it twice a week?
Solar, will it work after a few winters? It could be nicked as easily as a petrol pump and there is a fair bit unknown about them.

Its quoted at 60 PSI so it should lift 80ft, I would be more worried about weather it would cut back in to start pumping again when you have 80 foot height of water in the outlet pipe. Anyways, dropped the company an email so I'll let you know what they say. Here is a similar pump equipped with a pressurised tank. https://www.amazon.com/SEAFLO-Water-Pump-Accumulator-System/dp/B076JHCCBH

If these dont work then I'll look into a 12 volt version of submersible water pump and pressurised tank setup.

Anyone running solar setups on their farms?

Might be an option but I would have around 50 one to two year olds in the paddock at a time so I would want fairly big water troughs!!

If you are sure it will lift the water that high over that distance then you could always use it without the pressure switch (if pressure switch dosen't work)and use a big tank or IBC buffer tank then let it run manually while checking cattle daily.

I'm giving water to 12 weanlings using a 12v submersible pump and an IBC, I fill it once a week and run it off the tractor power outlet it fills the IBC in less than 10 min. Obviously you've more cattle but if you have a solar panel / battery there you could just switch on daily while walking up to check them and turn off when leaving.

I'm on a water scheme (gravity fed) where i pay for the amount of water I use. Reading some of these they will only pump circa 20% of the water therefore wasting the other 80% so this unfortunately wont work for me. It might be an option for lads with a river running past their farm that they can dam up to create a feed into the ramp pump.

Just seen this today. Looking into my options here:

Hi all, Just to let you know I that I looked up the maps to see the height of the hill on my ground versus the intake point for the water for the water scheme I'm connected to, Both are at the same height although circa 3 miles apart). With this in mind I got a role of piping at the weekend to see how far up the hill I can get with the water without using any pump. I was presently surprised to find that the water was flowing up at the top of the hill although probably less than half the flow compared to where I connected in the pipe. In any case with big enough water troughs it looks like I will be able to install the water network without any solar pumps.

Thanks for the advise in any case.

Water John

The diameter of your pipe is important, to lessen drag.

Fine Day

I went down the solar root after for my well. Bought a 24volt submersible pump with controller & solar panels. Very impressed so far. Have it hocked up to a 60litre pressure vessel with pressure switch to control the pump. Plan to connect fencer up to it next.

Yes water John, unfortunately the water scheme only allows a 1/2" connection, this is stepped up to 3/4" currently. I used 1/2" to try it going up the hill but when I install it properly I'll use 3/4"

Theheff, fair play to you, would you mind putting photos up of your set up and where you bought the various parts, I'd say there would be a lot of people on here very interested in the setup.

Water John

The size of the connection allowed doesn't matter, it's only at half inch for a few feet. If you saw the little opening inside the meter, you'd be amazed.
Not sure of the length and the rise you have and what draw you'd have, but the investment in a larger diameter pipe is really worth considering, inch or inch and a quarter.

feartuath

I have just built a ram pump using 11/2" fittings,there is not much of a fall in the river but it is 2 to 3 feet deep with a good flow.
Not sure if it will work even with 4" pipe feeding it
Hope to install at the weekend.

Maybe I need a mill wheel!

Water John

Love to know how you get on with that.

There is 3/4 inch going through one side of the farm already, Originally I was thinking of T'ing into this with a run a circa. 530 meter's covering four new drinking troughs and looping it back into the 3/4 pipe that is there already further down the field, that way water could flow in either direction in order to fill the troughs. Would this be good enough? Its €0.20c/meter more for Inch pipe so I'm thinking of putting this into the new section in order to future proof it. I could put down another 150 meters of Inch and bring the connection direct from water meter, would it be worth the extra investment? Wont be Dairy cows drinking here, only about 70 1 to 2 year old cattle.

Put in the biggest concrete troughs you can get, let that be the reserve if you want to use 3/4 pipe. I would have mobs of sucklers of 70-80 together and some troughs did come under pressure last summer. I'm on a mains supply and pressure is good. All 3/4 pipe here to troughs off a 1 inch main.

I tested the ram pump on Saturday,I have 500mm of 4"pipe feeding an 11/2" ram pump.
There is no fall in this river but 2 to 3 feet deep with a fairly good flow.
Pump did not work as not enough pressure going to it.

I took it to another stream with a small waterfall and it worked fine
I had no pressure gauge but when I opened the valve water shot upwards from it.

Back to the drawing board with the first location to test what can he achieved

Sorry to hijack the thread OP but I'm looking at putting in some sort of rainwater harvesting system on a small bit of land -10 acres. Anyone any recommendations? I haven't much research done on it yet to be honest. Tanks. (See what I did there......)

Four 300 gallon troughs going in so their will be a good reserve there. That will get water to eight paddocks that didnt have water in them before.

Water John

Ger I wouldn't redo the 150M unless there comes a need. Remember a one inch pipe takes four times the water of a half inch pipe. So three quarters falls in between and could possibly double your water supply if you get stuck.

Great job , looks like spillanes concrete. Only problem I have with them is bulls smash off pipe fittings if not more protected than you have there

The picture with the troughs in the distance shows each trough is servicing two paddocks so their is an electric fence going out over them with one stake placed close to the connections at the back of the trough to prevent them being damaged. The picture of the trough close up doesn't have this done yet as I have these two paddocks burnt off for reseeding.

Going back a bit. But would love to know how to feed water into the Ram Pump properly - like if it's on a stream how do you stop it being clogged with silt etc.

Is there a filter you can use for the 4" Pipe and how do you get a decent flow going through it?

You could try putting in a very basic stilling well, offline from the main stream flow channel so that your not getting much if any deposition on the pipe.

I gave up on the ram pump in one river but got it to work perfectly in another.
One case there was 3 foot of water in the river flowing slowly.
I used a meter of 4" pipe reduced to 3/4 to try and build up pressure to feed the pump but it was not enough.
You need pressure flowing into the ram pump first then this will in turn pump to a great distance across the field.

I was trying to make it extract from a slow flowing stream.
2nd time a few meters of 3/4 pipe primed with water flowing downhill was enough to get the pump to work.

Used home made wire mesh filter in plastic bottle attached in hydrodare pump work here in the past.

Have seen it done with three well liners, water fed on via a 2” stone drain.
Water was crystal clear and no sediment.

Was the 3/4 pipe normal guage black agricultural pipe?

The videos I've seen feed the water in with a galvinised pipe or a rigid sewer pipe - I was wondering if alkathene pipe would be OK to feed in water.

Bringing back an old thread here. Anyone successfully using solar to pump water? I’ve a small well that I could use for water for the cattle. No access to electricity. A solar pump would be ideal but paying thousands seems extreme for a small job.

Yes using few different pumps, can be put together for a few hundred depending on how many cattle you need to supply or how far/high you need to pump.

I am using this in a 24 volt version for the last 4 years. Have it connected up to a 60 litre pressure vessel and pressure switch (same as what you would have in a 230 volt system) works great. Have the fencer off it too. It's down around 120 foot in the well. Once I was happy with working I bought a spare pump and controller. Simple to hook up and run.

I think it's grant aided in TAMS.

I'm using the 12V version, I've had a pump fail this year, took it apart and the water had gotten in where it shouldn't, but that's a common problem for submersible pumps. It's still a cost effective solution though.

It does my job well anyways. Great pressure at the cattle drinker. I have it close to well. No problems yet apart from batteries, I normally use 2 old car batteries and I would get a year or 2 out of them. Granted the max amount of cattle that would be there at any one time would be 25 stores.

K.G.

Put in a solar pump last year and it has worked very well.the main advice I d give is put in a storage tankat the highest point in your system and let that be your battery.batteries only have a time in them whereas the tank is a lifetime job

Fine Day

If it's the same requirements as what I have (grazing march to November) Keep it simple. No storage tank needed. March to may & Oct to November cattle will need dam all water as the weather will normally be wetter. This time of the year there is plenty of sun light to keep the solar panels going. A 150 gal + drinker is all you need

I think we are all using solar pumping in slightly different ways and I'm sure they all have pros and cons. If I remember correctly @K.G. you have a much larger water requirement and your system suits the unique topography of your farm (there are no real high points on any of my farm blocks).

My setup is more like @Theheff but I'm using ICB tanks and float switches with a battery. The battery is important as it also keeps the electric fences going as these are remote farm blocks, I'm also using remote monitoring of the water supply so the battery is also needed for that too.

The ICB's give an extra 1000L of water as backup in case of failure which gave me a little extra piece of mind, which was more important when I was working away from home during the day, it's also a simpler plumbing setup and ICB's and the float switches are cheap.

@Sugarbowl we have no idea of your particular requirements, but a simple DIY solar water pump will cost €100's not €1000's to feed a couple of drinkers close to your well. The FIL has a pump from https://solarpumpsolutions.ie/ which was expensive but it provides water to a much larger area with many drinkers on it.

Sugarbowl

thanks for suggestions. I only need it to supply water to a few cattle so was thinking going direct from well to a water trough for a start. Something simple. The well is old. Good clean water though. Can’t say how deep. 20ft maybe. Something to get me out of a corner as currently drawing in water to those fields and it’s a dose.

K.G.

Just a general question.30 1-2 year olds how much water would they need in these kinda days
