New Zealand 2MW Photovoltaic Farm Project Purchases 2500kVA Photovoltaic Box Transformer

Successful Operation of a 2MW Solar Farm in New Zealand

New Zealand, widely recognized for its strong commitment to renewable energy development, has recently added another successful case to its growing solar power portfolio. A 2MW photovoltaic farm has now entered stable commercial operation, supported by a 2500kVA photovoltaic box-type substation supplied by ZTelec Electric Technology (Zhengzhou) Co., Ltd. The project highlights the importance of reliable power distribution equipment in ensuring efficient grid connection and long-term operational stability.

Project Overview

The solar farm is located in the Bay of Plenty region on New Zealand’s North Island. The project adopts an agrivoltaic design, where photovoltaic modules are installed at an elevated height to allow agricultural activities such as sheep grazing and crop cultivation beneath the panels. This dual-use land model improves land utilization efficiency while supporting New Zealand’s strategy of balancing clean energy expansion with sustainable agriculture.

2500kVA Photovoltaic Box-Type Substation Solution

The 2500kVA PV box-type substation provided by ZTelec Electric Technology is a core component of the project’s power system. Designed for a 10kV voltage level, the substation integrates transformer, switchgear, protection, and control systems into a compact enclosure. Its space-saving structure is particularly suitable for solar projects where land optimization is a priority.

Engineered for high reliability, the substation offers strong resistance to temperature variations, humidity, and electromagnetic interference. Full compatibility with New Zealand’s 50Hz power system ensures smooth grid integration and stable power transmission to the local distribution network.

Procurement and Technical Collaboration

ZTelec Electric Technology was selected after a comprehensive evaluation covering technical performance, international standards compliance, and overall project cost efficiency. The PV box-type substation complies with IEC standards and local grid requirements, enabling rapid approval and commissioning.

Thanks to its prefabricated and modular design, the substation significantly reduced on-site installation time and civil engineering workload. Compared with traditional transformer installations, the solution helped lower overall construction costs by approximately 15%, improving the project’s investment return.

Operational Performance and Benefits

Since commissioning, the 2MW photovoltaic farm has demonstrated excellent operational performance. The system achieves an energy conversion efficiency of approximately 98.5%, contributing to an annual electricity output of around 3,500 MWh. This clean energy production is sufficient to meet the annual power demand of roughly 500 households.

The box-type substation’s sealed structure and dust-proof design minimize maintenance requirements and reduce operational downtime. Its layout also supports the agrivoltaic concept by maintaining sufficient clearance under the solar panels for agricultural machinery and livestock movement.

The successful application of a 2500kVA photovoltaic box-type substation in this New Zealand 2MW solar farm demonstrates the critical role of high-quality, adaptable power distribution equipment in modern renewable energy projects. As New Zealand continues to expand its solar capacity, proven solutions from experienced manufacturers such as ZTelec Electric Technology will play a key role in supporting efficient grid integration, long-term reliability, and sustainable energy development.
