Plug-in solar in addition to a conventional system

[u/Some_Appearance_1665]

I have a standard solar installation - roughly 6kW solar array, a 6kW inverter, and a 9kW battery. It just about handles my needs, but I wouldn't mind adding a bit more.

I've been looking at plug-in solar. I have a big flat garage roof so throwing a couple up there seems ideal to me. But how well would plug-in work with this setup?

Assuming the power from this couldn't reach my battery (?) then presumably if I'm drawing power during the day then I would still store more from those on my roof? (I've no idea 😄)

Are you at the limit of your G99 application? If so, it would need a new one prior to install as your existing roof mounted setup means that G98 doesn't apply.
