Solar Market Outlook
Strategic Growth in Thailand’s Energy Future
Global PV capacity has reached 3,000 GW, and solar now accounts for 72% of renewable energy investment. Market structure is shifting as well. Small-scale solar investment has moved ahead of utility-scale, while behind-the-meter systems are projected to represent nearly 30% of global solar by 2060. Together, these signals point to a more distributed and demand-led energy landscape.
The broader outlook reinforces the same direction. Renewable energy is expected to overtake fossil fuels in the global primary energy mix between 2040 and 2050, increasing from 20% in 2024 to 63% by 2060. At the same time, electricity demand continues to be supported by long-term drivers including data centres, EV charging, and industrial electrification.
Thailand is entering this transition with strong momentum. Peak electricity demand reached 36,699 MW in April 2024, up 19% from 2021, and is projected to rise to 56,000 MW by 2037. Solar capacity is expected to grow from 5.2 GW in 2025 to 7.71 GW by 2031, with the installed base already approaching 9.9 GW including pipeline. The market is also being shaped by estimated tariffs of THB 4.9 per unit by end-2026, THB 200,000 personal tax deductions, BOI incentives, deregulation, and Thailand’s PDP 2024 target of 51% renewable electricity by 2037.
Within this evolving landscape, ION Energy, a subsidiary of Bangkok Cable (BCC), plays an important role in extending BCC’s perspective beyond infrastructure and closer to end-user energy adoption. As a leading provider of end-to-end solar energy solutions in Thailand, ION Energy brings proven capabilities across residential and real estate segments, with more than 6,500 installations delivered nationwide.
