The results demonstrate a practical, low-cost, and modular pathway to couple FPV with hybrid storage for coastal energy resilience, improving yield and maintaining safe operation during adverse weather, and enabling scalable deployment across cage-aquaculture facilities. Currently, the vast majority of east African aquaculture is open‐pond based. The adoption of modern and sustainable aquaculture technologies and practices—in this case study recirculating aquaculture systems (RAS)—will help the region increase food security and decrease its current reliance on. Photovoltaic (PV) aquaculture offers a promising solution for sustainable electricity generation for farm and grid utilization (SEG/FGU). The principle is straightforward: “solar above, fish below. Inspired by natural processes of nutrient cycles of the ecosystem, Sustainable Agriculture Tanzania (SAT) has developed an integrated aqua-agriculture system, fostering a harmonious.
