Abstract
En 中文
• A PVT–heat pump system stably maintained 28–30 °C rearing temperatures during winter, preventing ambient-driven drops below 14.5 °C. • The system improved biological performance, increasing annual yield by 37.33% and shortening the rearing cycle. • The hybrid configuration achieved stable PVT electrical–thermal efficiencies (≈19% and ≈18%) and an average heat-pump EER of 3.15 kWth/kWe. • Annual energy and carbon footprints were reduced to 5.76 MJ/kg and 3.45 kgCO₂eq/kg, confirming enhanced renewable-assisted efficiency. • Economic evaluation demonstrated strong feasibility, with an NPV of 38,514.36 USD, IRR of 21.56%, and a 4.54-year payback period
