Re 1: Doesn’t the solar add value to the home though? That makes it viable even if selling as you can sell for more.

Re 2: The incentive is potentially on the landlord in these cases, to rent out a solar powered home for more. 35% of Australian homes have rooftop solar, many of those are rentals, because people will pay $10 more rent knowing they will save $20 on their bills.

AFAIK most of the small scale solar systems designed for balconies and rentals aren’t intended to connect to the grid. They are designed to deliver power downstream only to a few DC appliances, falling back to a mains power adapter when there isn’t enough sunlight or battery power.
