The number of solar panel installations in New Zealand has trebled in 18 months, and most of them went onto homes.
From October 2013 to March this year the number of installations jumped from 1630 to 5367 - that's a 220 per cent increase, according to analysis released by the Electricity Networks Association.
Not surprisingly Auckland, as the biggest city, had the most solar installations but the top of the South Island had the highest concentration per person. Tasman had 41 installation per 10,000 people, much higher than the national average of 12 and the Auckland figure of 10. Wellington had the lowest uptake at 2.7 solar installations per 10,000 people.
Most of the new installations were in the major centres. Nearly a third during the 18 months were in Auckland with 16 per cent in Canterbury and 11 per cent in the Waikato.
