Curious,
For some time now I've been a bit of an anti-PV solar person. In my mind I
just don't see the math working as a net gain.
It gets a bit messier when you start adding in various governments tax
manipulations, but based on this alone...
$2NZ / W ~ $1.70 USD / W and $0.15 kWh electricity...

1kW of panel =3D $1700
Avg sunny 12 hrs / day
Panel offsets 12 * $0.15 of electrical cost per day =3D $1.80
$1700/$1.80 =3D 944 days

So basically three years for payback, not including mounting, wiring,
battery systems, chargers, maintenance, lost interest on the invested
capital, etc.
I would guess actual installed cost of complete system to run 3 to 5 times
the cost of panels alone (please correct me if you have better information)=
,
So effective payoff in 10-15 years - assuming nothing
interrupts their functional life span. (baseball playing neighbor kids come
to mind)

This is considerably better than the last time I did the math a few years
ago. At that time I was seeing 50 year plus payoff time making widely
optimistic
assumptions about maintenance costs. I may need to change my opinion...
