Harnessing the Sun: RPC's Off-Grid Solar Revolution at Matanivusi Beach Eco Resort Fiji



Nestled along the serene and uncrowded south coast of Fiji's main island, Matanivusi Beach Eco Resort beckons travelers to experience the epitome of a sustainably run paradise. Formerly relying on an aging 60 kVA diesel generator, the resort sought to revolutionize its energy infrastructure to reduce operational costs and minimize its environmental footprint. Rainbow Power (RPC) was engaged to design and install a reliable off-grid power system, marking a new chapter in Matanivusi's commitment to eco-friendly luxury.
