Lightweight ventilated BIPV system for low-load rooftop applications

Scientists in China have designed a ventilated building-integrated photovoltaic system that relies on flexible solar modules with a weight of 6 kg/m2. The system also uses an airflow channel under the PV panels to reduce their operating temperature and increase their power yield. Researchers at the Nanjing University of Science and Technology in China have designed a ventilated building-integrated photovoltaic system (VL-BIPV) that they claim may represent an optimal solution for rooftops with limited load capacity of less than 15 kg/m2. "The VL-BIPV system adds only 6 kg/m² of load when applied ...
