Hey Blue what type of a pier or what is the hexagon concrete thing the solar panel is up against ?
(my curiosity is at me now!)

Battery is an old car battery, we use 2, keep one on charge and swop them around every few days.

Yes m8, thats definitely bordering on defeating the purpose of the solar panel.

although I suppose you could argue you would have to change it every day without.

That panel looks like 20 watts might be optimistic too.

Nice fence though, but using approx 600 ma I guess, so would need a decent battery and a decent panel too.

Would go with a 50W panel and a 130Ah battery, then you can relax for the summer.

Cast concrete pier T, been there a long time, has a style on the left.

I have a B20 strip grazer (0.2 joules) along a river for about 150 meters it is the one where you replace the battery (can't be charged) but it uses 2/3 batteries a year so this year I connected it to a car battery and working fine I was thinking of connecting a small solar panel to it and maybe someone more tech savvy than me could tell me what wattage would I need.

I think you would not need much to run that size fence probably a 10 or 20w panel from Amazon would be plenty
The concern I would have is might you need a charge controller to prevent over charging the battery

Thanks for reply. Would a lower than 10W panel do or are they a waste of money.

djmc · 14-06-2020 10:33PM

I would think that it would be fine for that size all you need is enough to keep the battery topped up. Once you are not using it over winter when days are short

A bit of topic here. I want to pump water from a river to a field about 150 meters away there is no power on the farm. Would it be possibly to run a pump of a battery connected to a solar panel?

Yes absolutely. It's becoming a common option there are ready to go commercial products available and plenty of diy solutions too.

in the same boat here ( river fenced off for glas on out farm) pumping water up to IBC tank with petrol powered water pump and gravity fed to couple troughs. would like to automate it without spending big money. What type of pump should i be looking for?

Look up solar pump solutions.ie

They are a great solution to provide water to a large area. If you want something simple to replace the petrol pump that's filling an existing IBC then there are much cheaper options. A 12v pump, float switch, solar panel, charge controller and battery would cost a few hundred.

Something like that would suit me could not justify the cost of the ready made solution. Would the float switch be placed in the river?

No, float switch in IBC so pump starts when level in IBC drops and stops when it's full.

Could you pump directly from river to drinking trough with battery and solar panel

It's possible, you need a pump with a pressure switch to work with your troughs ball valve. But the IBC can add a bit of a backup in case of breakdown on a DIY solution.

emaherx · 05-07-2020 02:49PM

You said you need to pump 150m is there much of a difference in height between the location you intend on placing the drinker and the river?

Would a 12V pump and 12V battery do the job.

Do you mean without solar? Just charging the battery regularly?

was thinking of two float switches so pump will come on when ibc nearly empty and stop when nearly full. with 1 switch pump would be on/off every time cattle drank even a small amount of water. what is a charge controller?

Charge controller controls the state of battery charge, ie it'll stop the battery from over charging when full.

From water level in river to the drinker I would say a height difference of 8 meters

No, one should do. The float switch won't activate or deactivate until it has traveled up or down a considerable amount, so won't cycle everytime a cow drinks. Use the same type you'd find in a modern septic tank.

8 meters of a rise plus 150 meters of pipe.
Not a hope in hell that a 12v solar/battery pump will generate enough head pressure.

This is your main concern when buying a pump. make sure it can pump to this height and @ that distance.

Thanks for the replies
Any idea where to get the solar pump?

emaherx · 06-07-2020 10:06AM

For your case I'm not sure.

I normally by cheap 12V pumps from Amazon. But your requirment to lift water 8M and push along 150M of pipe is beyond anything I have experiance with.

From what I've seen on-line 12V pumps can range upto pumps capable of about 40M Head height, not sure how one would perform lifting only 8M but through 150M of pipe. 24V pumps can be capable of 100M+ Head but are obviosly more expensive. And there are 36V/48V and higher available. Generally googling for these types of pumps leads to the usual Chineese websites or E-Bay from China and Aus/NZ.

I'd be interested to see what pump is in the https://www.solarpumpsolutions.ie/. AFAIK their product is well capable of this senario. My Brother in law has one so I might just go have a little look.

I have looked at the ready made option from solarpumpsolutions and waiting on a price from them would say that it will be out side my price range.Would be interested to know what pump they use in their unit.
