Every island deserves Power it can count on
Cyclones, fuel shortages, rising costs, Pacific communities have faced them all. Solar and battery storage are changing that story, island by island, giving governments, businesses and families power they can rely on.
Why solar benefits the Pacific
Diesel Independence
Fuel imports can cost Pacific nations up to 25% of GDP. Solar cuts that exposure directly.
Energy Resilience
On remote islands, cyclones can cut fuel supplies. Solar and battery storage keeps power flowing.
Sustainability
Every solar project brings Pacific nations closer to their renewable energy targets.
Community Development
We prioritise local employment, procurement and training to strengthen the Pacific economy.
Pacific Solar Cases - Niue
Grid Connected Solar
Niue's 2.79 MWp solar and 8.19 MWh battery system saves NZD 4 million a year in diesel costs, money that can now be reinvested in healthcare, education and community wellbeing.
Pacific Solar Cases - Fiji
Off Grid Solar
Vatuvara Private Islands Resort in Fiji's remote Northern Lau Group runs entirely on solar and battery power with no grid connection and no fuel deliveries, just reliable power around the clock.
Building the Pacific's Solar Future since 1998
Long before solar was a growth story in the Pacific, Clay Energy was already installing it. Established in Suva, Fiji in 1998, Clay Energy has spent more than 25 years delivering renewable energy, engineering and maintenance services to some of the region’s most remote communities.
Since joining the Sunergise Group in 2026, Clay Energy now operates as Sunergise’s engineering arm on the ground in Fiji and the wider Pacific. The combination of deep local roots, regional experience, and renewable energy excellence makes Sunergise and Clay Energy strong partners for the Pacific’s most challenging projects.

FAQs
Understanding Pacific Solar
Largely, yes, often with a backup generator for rare periods of low sun. On Niue, a 2.79 MWp solar and 8.19 MWh battery system saves around NZD 4 million a year in diesel costs and has cut generator runtime from 24 hours to approx. 2–3 hours a day. Vatuvara Private Islands Resort in Fiji runs off-grid on a 396 kWp solar system with 680 kWh/400 kW of battery storage.
Yes, when they are engineered for these conditions from day one. Pacific sites combine salt mist corrosion, cyclone-strength winds, high humidity and intense UV radiation, so our equipment and foundations are specified for them from the start, backed by more than 25 years of experience in the Pacific.
Long-term operations and maintenance is planned into every project from the start. Clay Energy (based in Fiji) has installed and maintained solar systems across the Pacific since 1998. We also build local skills through each project, ensuring that knowledge and understanding of renewable energy remain within the local community.
Cost depends on system size (kWp), whether the system is grid-connected, hybrid or off-grid, and how much battery storage is needed. Contact our solar experts to arrange an initial site assessment or find more information here.
Timelines depend on project size, approvals, shipping schedules to the island and the utility’s grid connection process. We map these steps during planning and use our experience across several Pacific countries to spot delays early.
The Sustainable Energy Industry Association of the Pacific Islands (SEIAPI) and the Pacific Power Association publish technical guidelines for grid-connected and off-grid solar PV. Many countries also refer to Australian, New Zealand or US standards, and each utility sets its own grid connection requirements. Praneel Kumar, our General Manager of Clay Energy, serves as Vice Chair of SEIAPI, and we design and install to the standards that apply in each country.
