Taiwanese solar PV companies at Energy Taiwan 2025 expressed optimism about the self-generation market in ASEAN and are actively seeking opportunities for expansion and collaboration. GreenRock Energy (綠岩能源) has connected a 1 MW project to the grid in Thailand, while Hwan Tai Solar (環台光電) has begun construction on a 2 MW facility in Vietnam.
“This year marks the first year—our starting point for local development in Southeast Asia,” said Eta Tsai (蔡逸達), Vice President of GreenRock Energy’s International Development Department.
Taiwan’s solar industry, backed by mature experience in energy storage and module manufacturing, is well-positioned to expand into overseas markets, said Corrine Lin (林嫣容), Chairman and Chief Analyst at Infolink, speaking at the Solar x Energy Storage Innovation and Application Development Forum during Energy Taiwan 2025.
