Thailand's feed-in tariff for residential rooftop solar PV systems: Progress so far

This paper reviews Thailand's feed-in tariff framework for the support of solar power production and provides a feasibility analysis of residential-scale rooftop solar PV investment in Thailand under three scenarios. The initial phase of feed-in tariff support for solar power in the form of Adder gave rise to the dominance of solar farms, contributing currently to 99% of Thailand's solar power capacity. Since 2013, the government has begun to give a more focused support to rooftop solar power investment in the form of fixed feed-in tariff. However, the response to the government's feed-in tariff support for residential rooftop solar has been slow. Among many reasons, this paper argues that the lack of feasibility of residential rooftop solar power investment remains a key barrier. Under current market conditions, such investment could potentially be stimulated with the presence of a tax incentive and more attractive financing options. (C) 2015 International Energy Initiative.
