Two approaches to solar install. Thoughts appreciated!

Re reading it, I see where I've gone wrong! The oversizing helps the inverter start up earlier, run at max capacity for longer and therefore improve efficiency.

Thank you everyone

Cheers. Glad to help you get the best option for you and not whatever suits the installer best.

Tariffs will change but generating all your own energy will always be useful and I'm sure you'll end up with a system that will be flexible to work with whatever tariffs end up being in place.
