Abstract
Vietnam became the world’s third largest market for solar photovoltaic energy in 2020. Especially after the Vietnamese government issued feed-in tariffs for grid-connected solar photovoltaic systems, the installed capacity of solar photovoltaic applications exploded in 2019. From studies carried out in the relevant literature, it can be said that support policies are highly important for the initial development of the renewable energy industry in most countries. This is especially true in emerging countries such as Vietnam. This paper reviews the feed-in tariffs issued and deployed in different regions of Vietnam for grid-connected solar photovoltaic applications. Moreover, the paper takes a closer look at the costs of electricity production from these systems in relation to the feed-in tariffs issued in Vietnam. The results show that the gap between the levelized cost of electricity and the feed-in tariff for solar photovoltaic electricity is relatively high, particularly in regions with a lower irradiation potential.
Highlights
In recent years, solar photovoltaic (PV) energy has grown rapidly and strongly among renewable energy sources (RES) worldwide [1,2,3]
None of the analyzed papers examined the effectiveness of existing policy mechanisms, especially the feed-in tariff (FIT) mechanisms, in the investment and deployment of solar PV in different regions of Vietnam
This is a pretty good price compared to the FIT and weighted-average levelized cost of electricity (LCOE) for solar PV in Vietnam in 2019–2020; see Figure 14 [9,10,36,37,85,86,87]
Summary
Solar photovoltaic (PV) energy has grown rapidly and strongly among renewable energy sources (RES) worldwide [1,2,3]. Promoting the development of RES, including solar PV, is necessary in the current context of severe global climate change and the requirement for energy security and sustainable development [5]. This is in line with the spirit of the Kyoto Protocol in. In Vietnam, thehave weighted-average cantly reduced, along with the increase of capacity factors year on year; total installation cost has reached 949 USD/kW, reduced by 58% between 2016 and4 2020.
