PV inverter up/downsizing

Annoying as it may be to see that chimney shadow creep across the panels every day, it doesn't make economic or any other type of sense to solve it.  When the inverter dies I might consider doing something.

an alternative would be to fit an SMA Tigo optimiser to the panel(s) in shade. They work with any inverter and prevent one panel that is in shade bringing down the whole string

Now isn't it best to look for an inverter with export limiting?

Yes, had thought about that too, though not researched in detail.  I have SMA inverters (2 of them for the 2 systems) so would be attracted to this option but either way I would probably need to scaffold one or both elevations and presumably get someone in to add the Tigos.  Might bring the costs down to a more acceptable level but still £500 to £800 I would imagine for parts, labour and scaffold etc...
