good morning or good evening.
my project I have a river 40 m from our shed water height minus 1 m from the ground + 20 m flat
I would like to pump water to the tan shed that there is sun 9 am to 18 pm we are in the south I have retained a pump and a solar panel

is this panel sufficient to run the pump non-stop during the day.
thank you in advance for your advice.
Pumping over sun
Re: Pumping over the sun
In my opinion, no ...
The power of the pump is approximately equal to the power maximale of the panel, but this maximum power is reached only a few tens of minutes during the day.
One might hope that the pump runs with a reduced flow, but it is rather to fear that it does not even start.
For safer operation (even with a few clouds), a 20W panel seems to me a minimum.
PS
Be careful with this pump: depending on the model chosen, some do not support more than 30 minutes of continuous operation ...

Hello again
thank you for your quick answers for the ram pump I read your posts a lot but complicate my home too weak water current.
I will therefore provide a 20w panel for the pump, it specifies the site ... Our model BWV 04 (article code 53 90 90) allows permanent operation on 6 to 9 V thanks to the water cooling of the engine.
do you have addresses of other pump because at 14euro90 it seems fragile to me.

Please note: this pump is therefore designed for 6 to 9 V whereas the well exposed panel can easily exceed 15 Vgerald222 wrote:Hello again

I think that is indeed the risk.gerald222 wrote:do you have addresses of other pump because at 14euro90 it seems fragile to me.
Perhaps here ?

pumping over the sun
hi gerald222
you can always pump with your little pump, in a reserve very close to the river and then by gravity do the 40m flat to your shed.
I think the ram will be good in this case, with less than 1m20 you can do largely what you want, even with a very low flow, but 24/24 and 7/7
or another idea, a small paddle wheel which drives a mechanical pump to send the water 24/24 to your reserve.

it means that the pump will receive too much voltage ???? are there 6a9v panels or a regulator ????
The small panel of 10 watts will never go up to 14 volts with this pump and I doubt as gaston which starts well otherwise it will not rotate fast enough to raise the water enough, I would include a battery and intermittent operation using a little timer that you can find at Conrad!

The 10W, no, but the 20W probably.Alain G wrote:The small 10 watt panel will never go up to 14 volts with this pump
Personally, I would not put a battery in such a system.Alain G wrote:I would include a battery and intermittent operation using a small timer
The water tank is there to ensure storage, no need to also store energy.
In addition, a battery will necessarily age.
The "over the sun" pumping system is a good idea.
You just need to size the pump and the panel correctly (there are "kits" in which the elements are sized to work together as this one for example)
