Retail buy-back rates for solar power exported to the grid range from 7 to 17 cents, plus 15% if the system owner is GST-registered. Cost-effectiveness of a residential solar power occurs when system owners aim to use more of their solar power than what they export, by means of timed appliances, turning on appliances when the sun is out, energy management systems and battery storage. Commercial buildings that use power during the day can get a high return on th. [pdf]
We're working with the sector on New Zealand's renewable energy and low‑emissions transition. We're responsible for the governance and regulation of New Zealand's electricity industry. Solar power can help you become more self-sufficient, reduce your carbon footprint and reduce your energy costs.
Solar power in New Zealand is increasing in capacity, despite no government subsidies or interventions being available. As of the end of April 2024, New Zealand has 420 MW of grid-connected photovoltaic (PV) solar power installed, of which 146 MW (35%) was installed in the last 12 months.
In 2009, the average turnkey price for a standard PV system of three kilowatts (kW) was about NZ$40,000; by 2019 this had dropped to approx. NZ$8,500. As of the end of December 2023, 56,041 solar power systems had been installed in New Zealand.
For new installations added in December 2023, the average residential system size was 6.1 kW and the average commercial system was 46.9 kW. The largest solar power system on a school in New Zealand was officially opened in a ceremony in February 2019 at Kaitaia College.
The largest solar power system on a school in New Zealand was officially opened in a ceremony in February 2019 at Kaitaia College. Kelvin Davis, unveiled a plaque to acknowledge the installation of the 368 solar panel project which is spread across the rooftop of multiple buildings on the school campus.
Going solar helps the environment - it creates clean, green energy and is a great way to reduce your carbon footprint. Going solar demonstrates your commitment to sustainability and will help New Zealand achieve its target of net zero greenhouse gas emissions by 2050. Is your property suitable for solar?

Some dramatically different approaches to EV batteries could see progress in 2023, though they will likely take longer to make a commercial impact. One advance to keep an eye on this year is in so-called solid-state batteries. Lithium-ion batteries and related chemistries use a liquid electrolyte that shuttles charge around;. . Lithium-ion batteries keep getting better and cheaper, but researchers are tweaking the technology further to eke out greater performance and lower costs. Some of the motivation comes from the price volatility of battery. . The Inflation Reduction Act, which was passed in late 2022, sets aside nearly $370 billion in funding for climate and clean energy, including billions for EV and battery manufacturing.. [pdf]

There are over 24,000 NissanLeafs in NZ (and counting). The LEAF is one of the first mass-market EVs, and its batteries degrade more than those. . There are a few things to look for. 1. SOH – State of Health (%) This number shows the battery’s capacity compared to when it was new. 2. QC – Quick. . Battery health can be estimated by looking at the dashboard bars. This doesn’t provide much detail, so a tool called Leaf Spyis used. . Contact one of the companies above. They have better diagnostic tools (than LeafSpy) to ensure your battery replacement is in good condition. While you can buy a used battery. [pdf]
There is also at least one commercial operation in NZ: Counties Energy now has a functioning 240 kWh battery (made from 18 Nissan Leaf batteries). The battery charges during low-demand off-peak times and powers the two EV chargers at the site.
There are no large-scale systems exist for LEAF battery replacement in New Zealand. Enough vehicles are being scrapped (i.e. written off by insurers) to ensure a steady supply of batteries that can be installed into other vehicles. Contact one of the companies listed below that can do the installation. DIY?
We took the base model 2022 Nissan Leaf 40kW for a week to test it out as a daily commuter. What’s In The 2022 Nissan Leaf Range? New Zealand sees two models of the Nissan Leaf, separated only by battery size. The 40kW model has a WLTP range of 270km provided by a 110kW electric motor that pumps out 320Nm of torque.
Note: Newer 40 kWh Leafs (2018-) are not following the same degradation curve. Telematic data from FliptheFleet shows a flattening off of degradation (consistent with other modern NMC batteries). New battery in a Leaf with maximum range.
In saying that, we haven’t forgotten all of the e-NV200 owners out there and we are currently prototyping an awesome 40kWh battery design with enhanced thermal management specifically as an upgrade for e-NV200s that originally had a 24kWh battery. What does RED, BLUE, and GREEN mean? 16 Blade has three planned variants named RED, BLUE, and GREEN.
Perhaps coincidentally, in late 2019 Nissan USA released a 40kWh pack pre-programmed to be compatible with 2016-2017 Leafs which were originally fitted with 30kWh packs. This clearly goes against their earlier claims. At this point their official upgrades do not extend to earlier 24kWh Leafs. You can learn more about this over on our news page.
