New Zealand's government has agreed to act on 15 recommendations from a sector review of small- and medium-sized solar installations, according to pv magazine. The package includes legalizing plug-in solar, next-working-day approval for systems under 10 kW, and sign-off by accredited installers, without an inspection, for installations below 100 kW.
The cost effect is the sharpest part of the reform. Analysis previously released by the Ministry for Regulation found that implementing the report's recommendations would cut average approval for a residential solar system from around NZD 640 and three months to NZD 200 and six days, pv magazine reported.
The ministry put the aggregate gain at between NZD 28 million and NZD 50 million in net benefits over ten years, attributing it to lower compliance costs, fewer delays and the use of plug-in solar.
The consenting changes land on a small installed base. Cumulative solar capacity in New Zealand reached 836 MW at the end of last year, according to figures from the International Renewable Energy Agency (IRENA) cited by pv magazine.
Grid-access rules for the same customer segment were reset earlier in the year. New Zealand's electricity authority introduced a 10 kW default export limit for residential solar and battery systems in April, a step intended to standardize grid access. That threshold matches the capacity ceiling now proposed for next-working-day approval.
Utility-scale build is moving in parallel. The country's largest solar farm to date, a 150 MW project on the north island, came online in July, pv magazine reported. That single site is equivalent to a substantial share of the 836 MW counted across the whole market at the end of last year.
