Photos: These kinetic solar crown clusters could generate 210,000 kWh of energy annually

The Fiji Solar Crown, developed by MASK Architects in collaboration with TesserianTech, is an innovative solar-integrated living system designed to address energy and water challenges in island nations like Fiji. This system features a Dual-Axis Concave Mirror Crown that transforms residential units into self-sustaining power plants, combining cultural respect with advanced engineering. Inspired by traditional Fijian bure architecture, the design replaces the roof apex with a parabolic solar mirror that tracks the sun with dual-axis rotation, optimizing solar energy capture while also harvesting rainwater and providing shading to create a cooled microclimate. The system is modular, available in three sizes—3, 5, and 7 meters in diameter—each tailored to different community needs, from localized agricultural power to residential use in floating villas or hilltop homes. The flagship 7-meter module, arranged vertically over three levels, supports residential living with communal, domestic, and observation spaces. Clusters of these units can generate substantial energy, with ten
