An avoidable dispute is interfering with the progress of residential solar power in Australia.

Here's an idea: the Australian government should arrange to finance solar power systems and batteries for rental housing, and get the money back over time by charging through the electric bill.

Massachusetts used a similar system decades ago to replace old, inefficient hot water heaters. The tenants saved money, because they payments for the new heater were less than the savings due to its increased efficiency. The landlord lost nothing so did not object.
