The global solar energy market is projected to exceed $100 billion in 2026, fueled by an insatiable demand for electricity from data centers, manufacturing, and the electrification of transport [1]. For Southeast Asian manufacturers, this presents a massive opportunity. However, the landscape is no longer defined by simple cost arbitrage. Instead, it is being reshaped by a wave of policy changes in its three largest markets: China, the United States, and India. As Wood Mackenzie notes, 'Solar will remain the primary source of new power capacity additions globally through 2030, but the path to market is becoming increasingly complex' [1].
For Southeast Asian exporters, the most critical development is the scheduled termination of the US Section 201 safeguard tariffs on imported solar cells and modules in February 2026 [2]. This policy, which has imposed a 14.25% tariff on top of existing duties, has been a significant barrier. Its removal opens a crucial window for compliant manufacturers. However, this window comes with a caveat: the US market demands rigorous product safety and electrical compliance. The primary gatekeepers are UL certification (specifically UL 61730 for PV modules) and adherence to the National Electrical Code (NEC) Article 690 [3]. Without these, entry is impossible, regardless of price or quality.
Meanwhile, India, the second-largest buyer market from Southeast Asia, is moving in the opposite direction with its Basic Customs Duty (BCD) and the Approved List of Models and Manufacturers (ALMM) [4]. The BCD imposes a 40% duty on imported solar cells and 25% on modules, while the ALMM restricts government-backed projects to only those using domestically manufactured or pre-approved components. This creates a two-tiered market: a protected domestic segment and a more open, but highly price-sensitive, commercial and residential segment. Navigating India requires a clear understanding of which segment you are targeting and a potential long-term investment in local assembly or partnerships.
In contrast, the Philippines, the third key market, offers a more welcoming environment. Its Renewable Energy Act of 2008 (RA 9513) and supportive Net Metering Rules have created a stable, growing demand for both residential and commercial solar installations [5]. While technical standards exist, the regulatory burden is significantly lower than in the US or India, making it an ideal testing ground for new products and business models.
