2MW Floating Solar (FPV) Installation
Nantong, Jiangsu, China · Water treatment authority
Modules Supplied
3,125 × JUSTSOLAR TOPCon 640W bifacial
Challenge
Water treatment reservoir (unused for ~2 years awaiting infrastructure upgrade). Municipality wanted productive use of underutilized land/water. Needed floating structure stable enough for 25-year lifetime. Panels had to avoid algal growth and water quality impact.
Solution
HDPE pontoon-based floating structure with JUSTSOLAR TOPCon 640W bifacial modules. 10° tilt optimized for local latitude. Panels provide shade reducing algae growth (15% reduction in evaporation, 20% reduction in algal bloom risk). Submarine cable to shore inverter station. Modular construction allows future capacity expansion.
Results
Energy output 3.5% higher than projected due to water cooling effect (modules operating 4°C cooler than ground-mount equivalent). Reservoir evaporation reduced by 18%. Project won regional 'Dual Benefit Solar' award. Now used as reference site for FPV development in China.
