Solar panels and battery - any real world reccomendations?

I am torn between a few solar panels, inverters, and storage batteries. I tried looking through quite a few threads if anyone has covered the topic but here are the choices i have but every installer comes with different jargons :
_______________________________________________________________________________________________
Solar Panels: Canadian Solar CS6R 410 Watts
Inverter: Sunsync Hybrid 8 KW
Battery Storage: Sunsync 5.2 Kw
_______________________________________________________________________________________________
Solar Panels: Perlight Delta 415W (1617 x 1140 x 30 mm) 30 years material and lenear power warranty - 21.2% efficiency
Inverter: G2 GivEnergy 5kW hybrid inverter
Battery Storage: Gen2 GivEnergy 9.5kWh LiFePO4 Battery

Advantage: GiveEnergy connects to Octopus energy well but the
Disadvantage: GiveEnergy storage battery voltage is 51 volts which is low for charging and discharging to the grid
_______________________________________________________________________________________________
Solar Panels: Sharp 400 Watts
Inverter: Sunsync Hybrid 8 KW
Battery Storage: Sunsync 5.2 Kw
_______________________________________________________________________________________________
Solar Panels: Renesola 400 Watts
Inverter: Hypontech Hybrid 6kw
Battery Storage: Soluna Battery
_______________________________________________________________________________________________

Solar Panels: Leapton 400 Watts
Inverter: Fox Inverter
Battery Storage: Fox Battery

https://www.theecoexperts.co.uk/solar-panels/best-solar-panels.. i'm thinking the same so many to choose from ..
 
So the rest of my install has been cancelled today, no panels going up, G99 application has expired apparently - Nobody contacted me, I had to call them to find out why, E.ON are really in a mess right now. So I have scaffolding that's got to come down and be put back up in ~40days. At then end of this fiasco I'll have used up 7 days of my holiday allowance for 2023.

So done some research, last part is the worrying part :

Connection offers are valid for 90 days after which they automatically expire.
There are circumstances we may enable a single extension to the validity of the acceptance for a further 90 day period, provided there is no detrimental impact to other customers in the connection queue. To request an extension the Customer must submit a request, in writing, no more than 10days prior to the original connection offer validity expiry date. Upon receipt, we will confirm the revised expiry date or issue a letter outlining the reasons for refusal of the request.
We may withdraw a connection offer if the project is not progressing at a reasonable rate.

I don't understand this negative point. What's battery voltage got to do with charging / discharging from grid?
 
Givenergy rates are actually limited by the inverter. 2.6kW for G1 hybrid, and 3.6kW for G2 (there is talk of an update coming to increase the G2 one a bit).

Both of these are fine for most folk, though admittedly G1 is a little weak, and it's one of my only gripes.

Put in a complaint and ask for a reduction to match your value of you holiday.
They will probably say no but push for a while and you may secure some discount.

Twitter is probably a good place to start.

Which DNO is it?

I'm with UKPN and got 6 months to 'accept' the 'acceptance', I nearly missed the fact that I had to accept it, and accepted it on the final day, then I had 12 months to install the system, once commissioned its 30 days to notify them.
 
I found this on the GE community but it does appear that there may well be an Octopus/GE tariff still in the works, which I'd be very interested to know more about.

Yes, I was pondering whether we jointly build an official OCUK excel model that could cover all the common questions that constantly come up in this space, eg:

- Octopus Flux vs Go vs Agile vs etc
- Best battery/inverter split
- Best Ron-ski excuse generator for why he's lower than Katie....

Still worth a poke around above!
 
Does anyone see their solar PV generate much more than the system rating? I've a 5.3Kw system (Canadian solar 415W panels x 13 ) currently producing 5.4Kw (Fair enough, lunchtime, no shade SSE facing ) On Tuesday at 10am the growatt app shows it as producing 6.12Kw dropping to 5.45 by 10:35, not the sunniest day but wondering if this is normal.

End of week 5 Feb 16 - Mar 23rd , 395Kwh produced from a 5.3Kw system in Fife, boosted by a few 20Kw+ days, lowered by more than a few <2kw days. I'm pretty happy so far ( Currently hoping EST get their finger out and pay for it before my credit card bill is due :D )

There's going to be some error margins and tolerances in all panels and inverters, that said that's over 10% difference but it's probably just temporary peaks.

Just be happy that your system is functioning well! :D
