I didn't get your trampoline joke you can say I understand the poen.
I know it is funny but trust me I'm 90kg+ bloke and I was walking and jumping on it when it was ready and there was no any problem with it. So really no bending issue. Fence behind the panels is protecting the panles from uplift force. If the storm is so huge and ripping of the fence than possible the damage what my panels will cause that will be the smallest thing.

I'll stop now as it is far too early in the morning for my pigeon Hungarian
I understand what you are saying about the wind forces – it’s just that I have seen heavier structures than yours blow away and as a minimum I would like to see the frame ballasted or cemented in place. That size of array will be exerting much more than 90kg of pressure in storm conditions. Like I said I'm not concerned with your frame bending under the weight. If it folds up and collapses to the ground the only thing harmed is your wallet (and a little bit of pride). But what you have built is essentially a giant wing - you don't want it taking off! Uplift is caused by airflow and pressure differences - in such cases you are concerned with far more than the direct action of wind pushing against the panels.
Experience has shown that most panels are sucked off, not blown off!
Secretly I am quite impressed with the frame you have built - but building control may have other ideas.
My experience in Hungary is that you can do pretty much what you want unless you catch the eye of any one with a hint of power - then it's just a matter of how much you have to pay them to find someone else to annoy. That's why I don't even look at a rendorseg when I'm out and about.
The experience here is rather different - but probably just as expensive.
I certainly wouldn't throw away what you've built - just make damn sure it stays in place!
How you approach building control is up to you - and how tetchy your neighbours are.
Lets just say I have seen far worse installations carried out by accredited PV installers and building control have not been involved unless panels have ended up in somewhere other than their original location…
As I’ve said, as long as the AC side of the installation is certified you will not have any problems with your DNO or electricity supplier. All they need to know is that you have a G83/2 inverter, you won’t be exporting at more than 16 Amps, that your import meter doesn’t go backwards and the system is correctly labelled.
We could help you with that part, but not the connection and commissioning of the DC / Solar panels. That part is not rocket science and I did not mean to imply any lack of knowledge on your behalf – just make sure you fit the correct connectors (all the same make – do not believe anything that says MC4 compatible) etc and you’ll be fine.
If we can be of help to you for the AC side please message me - our electrical team is based in Chelsfield, Kent.
