2.3. The definition of extreme low-light event. Generally, when the amount of solar radiation falls below 100 W/m 2, most photovoltaic facilities in China lose the ability to generate electricity stably [41].Consequently, the day with ground incident solar shortwave radiation below 100 W/m 2 is regarded as low light. However, to ensure uninterrupted …
