Decision 11/2017/QD-TTg of the Prime Minister on the mechanism for encouragement of the development of solar power projects and Decision 13/2020/QD-TTg setting out a legal framework for the next generation of solar power projects
On 12 September 2017, the Ministry of Industry and Trade issued Circular No. 16 for implementation of the Prime Minister's Decision. The Circular establishes guidelines on the formulation and approval of national and provincial solar power development plans, technical requirements, and tariff structure for grid-connected projects and rooftop projects. A net-metering scheme is included for rooftop projects.
On 6 April 2020, the Prime Minister passed a decision to update the legal framework around solar projects.
On 17 July 2020, Circular no. 18 was issued by the government to replace Circular no. 16. It updates the regulating framework for small and large-scale solar installations, as well as the feed-in tariff scheme, and was complemented by Official Letters 3288 and 7088 in September 2020.
