.......What make of panel is it, think I might buy a couple
It is a Sunshine Solar 120watt monocrystalline panel with the Dual Battery Controller and remote monitor.
Don't forget the current is dependant on the battery state as well as the sun and location - currently in Bideford The 4.5 A this morning was, I think, about 11.00 and yesterday the 11A was about 15.30 - maybe a bit before This morning the batteries we well charged and I put all the load on that I could to give some space in the battery.
I am so amazed that I'm contacting Sunshine Solar for their comments
Keep us posted if you will?
Take onboard your comment about the state of batteries etc.
Although I thought the maximum amount of Amps through the panel is fixed by the panel itself?
When it's sunny, my panel is capable of 8 Amp per hour, but if the batteries are only wanting a small 'top up' then the system will only drip feed the necessary ampage, this could be a little as 1 amp, even if the panel is capable of producing 8.
Location: Bideford - a good place to test juddering Fiats and electric bikes.

....Will be interesting to see Sunshine's comments.
Cheers..w
Have just got this from them - not very satisfactory so have gone back to them to see if they can/will say more
Dear Tim
Glad you are happy with the panel we have had other customers with different solar panels saying the same recently the weather conditions have been very good long may it continue.
Thanks for the email

It is also interesting to note the very large range of panel efficiencies - from 9% to 15% for the best. That's a 66% better than the lowest

It's all to do with the test conditions, if the reality is that the weather is better than the test conditions it is possible to get better results.

I don't think so I'm afraid. The manufacturers quote the maximum output of a panel at a sun power of 1000 watts per square metre. I refer to our resident expert's guide on this forum (Frank - Sallytraffic) whose profession before retirement included the installation of large industrial solar systems.
In the guide he states:
"So this 1,000 Watts per square meter how much sunlight is that? Its about as bright as it gets at the earth's surface. You don’t really have to worry about that though."
So, referring to my own recently installed Kyocera 135W specification. The max output at 1000 W/Sq Mtr is 7.63 amps.
Sorry to draw a cloud over your apparently magical 120W panel. I would suspect the guage.
hi, i have a 130w and an 80w with a mppt charge controller and the maximum i have seen is 11.5 amps and the 130w panel tilts face on to the sun as well. all the best sean
My 80w panel rated at 4.7 has in the past registered 5.3 on a Fox-D1 gauge.
I have noticed that I almost always get higher readings if there is a decent discharge due to low batteries or something else (laptop?) being charged.
