I still can't see how any plug and play kits can be marketed in the UK when we don't as yet know what standards they need to comply to? How will any company be able to ensure the kits will conform to the rules, and they will be changed within the 90 days?
I look at my own solar, and how my bill is near enough zero
not quite zero, but getting close with £0.88 monthly payments.
So if someone fits balcony solar, and they see £16 reduction in their monthly bill, then seems likely they will buy another kit. Sunny side of my home is all on the same ring final. So what happens if I plug in three x 800 watt systems? Even as it is, I have not tripped the 32 amp RCBO in the 4 years fitted, so in real terms overload is unlikely, but nevertheless, adding 10 amps does not seem prudent.
This morning the news says "
" Come on, make your mind up, one minute wanting more, next wanting less solar.

This must be considered daft. On a slag tip where nothing will grow, OK, but not on good land.
