Vietnam is currently the leading country in the Association of Southeast Asian Nations (ASEAN) in terms of installed solar and wind power generation capacity (Figure 1). This is largely due to its rapid photovoltaic (PV) solar uptake, which resulted in total solar and wind power capacity reaching over 17,000 megawatts (MW) by the end of 2020 [1]. More than 100,000 rooftop solar PV systems were installed in Vietnam in 2019 and 2020. In per capita terms, Vietnam’s cumulative solar and wind power capacity reached 176 W by the end of 2020, the highest in ASEAN [1].
