The project involved the installation of three interconnected, ground-mounted solar arrays in western Tongatapu – the country’s main island. Each has a capacity of 2.3 MWp and was built with the help of local civil, mechanical and electrical sub-contractors. It is backed by a power purchase agreement (PPA) between Sunergise New Zealand Ltd and Tonga Power Ltd.
The completion of the project was first delayed by the COVID-19 pandemic and then the eruption of a submarine volcano in the Tongan archipelago that caused tsunamis.
