December for us, we are in the cool(ish) dry season so every day is a "work on the solar" day
I was lucky with my lady, started her off with a small system (4 x 300W panels and a couple of cheap micro-inverters).
Madam immediately spotted the potential for reducing our power bill (OK I showed her our conventional meter going backwards).
We are now at 10.6kWp of grid-tie hybrid with 10kWh of storage, plans for another 2.6kWp of panels and 20kWh of storage.
Solar is an addiction!
For our other addiction we have Madam's "pot plants"
