Solar power in New Zealand
We’re committed to increasing solar generation in New Zealand. There are roofs all over the country that could become renewable energy generators, and a huge opportunity for growing solar for our commercial customers. We’re excited to be leading the charge and partnering with Kiwi businesses to get there.
Solar for your home
We’re proud to support customers who generate their own 100% renewable energy. And if they generate more than they use, we’ll buy the electricity back at an agreed rate and credit their next bill.
Commercial scale solar
Meridian is making watts while the sun shines with our solar installations across New Zealand.
We’ve helped establish New Zealand’s largest commercial solar programme, installing solar across Kiwi Property shopping centres in Christchurch, Palmerston North, Auckland and Hamilton.
Through our innovative, flexible contract options, we’re empowering more New Zealand businesses to go solar and make choices that help them do better for the environment, as well as their customers, staff and communities.

Maama Mai solar farm
The Maama Mai (let there be light) Solar Farm in Tongatapu, Tonga is an alliance between Meridian, Tonga Power and the governments of New Zealand and The Kingdom of Tonga. The project is funded by the New Zealand Aid Programme.
The solar farm is made up of 5,760 photovoltaic solar panels and can generate up to 1.32 megawatts of electricity. The Maama Mai solar farm reduces the country’s use of diesel by approximately 470,000 litres and decreases carbon emissions by over 2,000 tonnes per annum.
This is the first solar farm we’ve built in the Pacific, and the first renewable energy generation facility connected to Tonga’s electricity grid.
Tonga Power is responsible for operating and maintaining the facility. In 2017, full legal ownership of the solar farm will transfer to Tonga Power.
We will continue to provide asset management support to Tonga Power until 2017.
Why build a solar farm here
Before the solar farm, electricity generation in the Kingdom of Tonga was solely dependent on the costly importation of diesel fuel.
Maama Mai will provide around 4% of Tongatapu’s total electricity demand, helping Tonga towards its renewable energy target.
The solar farm will reduce the country’s use of diesel by approximately 470,000 litres and decrease carbon emissions by over 2,000 tonnes per annum. It will also help reduce electricity prices.
Solar generation compares favourably to other forms of renewable energy generation available to Tonga. It has low maintenance costs and is relatively quick to implement.
Building Maama Mai
In 2009, Meridian presented a proposal to the New Zealand Aid Programme identifying Samoa, American Samoa and The Kingdom of Tonga as suitable places to build solar farms.
The proposal coincided with the Tongan Government’s Tonga Energy Road Map (TERM), which is focused on reducing the Kingdom’s reliance on fossil fuel.
In 2011 the New Zealand Government, through the New Zealand Aid Programme, offered full funding of NZD$7.9 million for the Tonga solar farm project.
Meridian was lead developer on the project, using our solar expertise gained during construction of the CalRENEW-1 solar farm in California.
