Okay this in in OZ and maybe they get more sunshine.

Kind of messing up the business model for the home owner of being able ti
get some money back for your excess power.

There are some good examples of the benefits of installing solar
panels, but the following article shows that New Zealand has been very
slow to take up solar power.

Solar certainly provides a good investment return as well as helping
our country. It is also possible to fairly cheaply store some power. I
know one family that is using a couple of old electric vehicle
batteries - they have linked them to solar panels, but also linked a
computer to control when they charge their electric vehicle and when
they allow transmissions to the grid to minimise costs.
There has also been talk of using large roofs on school buildings to
generate electricity for use by the school, or for loading to the grid
when the school is closed. That is effectively what has been done in
Germany - it reduces costs in the local area, and would be a lot
cheaper than importing coal or other fuel.
