The Price of a Solar Power System
The price for grid connect solar power system is now less than 1/4 of what it was seven years ago. Because of the massive drop in solar power prices, systems are more affordable for New Zealanders and it can be thought of as a really good investment.
A standard 3kW system size seven years ago cost $40,000, now in 2016 it averages at around $10,000 to $13,000 (completely installed).
The cost of a solar power system varies depending mainly on the system size you select and the type of roof you have.
Below is a small sample of residential system sizes and the rough price of each:
1.5kW - six 250W panels - on a metal roof - *$6,000 inc GST, fully installed.
3kW - twelve 250W panels - on a metal roof - *$10,000 inc GST, fully installed.
5kW - twenty 250W panels - on a metal roof - *$16,000 inc GST, fully installed.
*Please only use these prices as a starting point if you are thinking about going solar. Prices can vary based on a number of factors.

Should I Hold Off From Buying a Solar Power System?
Because the price of solar power has plummeted dramatically over the last decade, we don't expect the same drastic price drops in the future. I would recommend that you can expect to see a 3kW solar power system drop no more than $1,000 in price every year (based on current trends). You might be able to buy a solar power system cheaper in a few years time, but the opportunity cost is not saving on power bills over those two years.
There is a possibility that solar power system prices could go up. If there is ever going to be an increase in price, it will likely be due to exchange rates.
The technology for solar power has not had a revolutionary change over the last 10 years, the energy collection concepts are the same, but the technology does tend to get a bit smarter and a bit more efficient over time. Technologist are improving the efficiency of solar panels every year. This is the efficiency at which the panels convert sunlight into power. According to GTM research conventional panels are likely to improve by approximately 0.3% annually, which isn't fast by any means.
Are There Subsidies For Solar in NZ?
There are no subsidies or incentives in New Zealand for homeowners to install solar power systems. The Government did provide subsidies for solar hot water systems for a few years, but that never applied to solar power.
