Flagship solar energy projects in Thailand are becoming increasingly innovative: the state utility, EGAT, is tendering a 24 MW floating solar array at Ubol Ratana Dam, the first phase of a 2. 7 GW hydro-floating solar hybrid program that avoids land-use conflicts while. Solar energy is slated to be Thailand's largest renewable energy source in the coming years. While growth has been steady, rapid deployment is needed over the next decade to make longer-term. he-metre installations. This gap is due to several policy, regulatory and inancial risk. In Thailand's current context, investment in rooftop solar systems is not merely a rational economic decision but also a forward-looking commitment to sustainability. The framework aims to shift political and commercial focus beyond cost to include value. Economic Forum, supported by Accenture and a group of. However, when viewed holistically, these developments clearly point in the same direction: a structural transformation of Thailand's power system to integrate solar energy as a core component rather than a supplementary source. A recent amendment by the Ministry of Industry to the Factory Act eliminated the requirement for a factory licence for rooftop solar installations with capacities exceeding 1 MW. This regulatory change presents new.
