I’m paid 24p for my export, my system has only been in 2 weeks and have already generated £26 of grid export

Sounds like one of those incentive rates to get you to have your solar installed in conjunction with an energy company. You have to remember 99+% of people cannot access those rates and its usually all baked into the purchase price.
I've no idea. It's what the MCS person said, and also the IET guy - spoke to the latter for quite some time.
I've also got cables touching the roof tiles - not sure if that's a problem too?
The potential issue with cables touching tiles is they could eventually rub through the insulation, nowadays there is an assortment of clips and accessories available to secure them, but I'm sure it would take twice as long to install if they did.
My original install has cables touching the tiles (installed 10 years ago), my WNW roof also, even though I put quite a bit of effort in to tidy up after the electricians on that roof has a few as well, its almost unavoidable unless you take a lot of time to do it.
The cables in the picture above I'm pretty sure will be the ones going to the panel, the hardest ones to secure away, as when you put the panel in place there will be some slack in the cables.

Thanks - I think for those smaller lengths of cable I'll not worry too much. Thank you!

Looks like there are now at least 3 cars sold in UK that support V2H/V2G - Renault 5, BYD Seal and Model Y Performance. Sigenergy SigenStor bidirectional 25kW DC charger is very expensive, like 3500 quid. The Tesla charger, if I understand correctly, will require a future software update and a compatible inverter, like Powerwall 3 for the full functionality.
The Octopus BYD Seal offer is very interesting, but currently the wait list is only for people who don't have solar.
The use of EV as home battery will make running heat pumps cheaper, as it will let people completely power the home heating on cheap night tariff.

Which is what I already do, with the only caveat that the very coldest days will likely eat through my 29 kWh battery, mine being a house battery it can still power my heating/house when my cars at work or anywhere else other than at home

Renualt 4 as well (admitedly underneath it's practically the same as the 5)
I regret not getting a bigger battery (5kw with my 5kw fox inverter and 12 panels split either side of building due to position) but give it a couple of years and I'll likely end up with a 4/5/Surf anyway...
I haven't seen yet a single video by YouTube influencers of bidirectional charging working in UK - outside of old Nissan Chademo bidirectional chargers.
It can be a game changer for a lot of people. Something like 20% of the new cars in UK are purchased by Motability - a person on say disability benefits can get an EV from them (up to 100% funded by the government), that comes with a free charger - can then go on Intelligent Go tariff, and power the home during the day from the car. This will save them a lot of money.
