An article in Gizmodo referring to Australian solar installs says, 'No longer are just inner city rich people getting solar power installed.'
A study carried out in Brisbane by Dr Sommerfield found that the demographics of those people installing solar in Australia had changed dramatically over the last few years. Moving away from rich older couples to younger families in bigger homes in the outer suburbs. As the price of having solar installed declines it is no longer just the weathly that are able to afford to install a solar PV system.
In New Zealand we are not seeing this happening yet, although at PowerSmart we have seen a massive increase in people building new who are installing solar PV when they build. The other growth area of course has been in off grid and commercial solar installations, both of which make sound financial sense. Commercial solar because businesses operate during the day when peak power production occurs and off grid because of the cost of making new connections to the grid is often more than having a complete solar off grid system installed.
