A key feature of this Cloud Class was exploring the “Distributed PV (photovoltaic) Model”, a solar power generation setup situated on the rooftop of the Dazhai Nine-Year School about 1,700 kilometers away from Tianjin University. In 2022, the School of Electrical and Information Engineering conceived and implemented this system, which has since generated nearly 50,000 kWh, equating to an electricity savings of over 30,000 yuan. The proceeds have been donated directly to Dazhai Nine-Year School, enhancing its educational facilities and resources.
