Shares of solar energy companies are experiencing a collective pullback in the Hong Kong market. At the time of writing, XINTE ENERGY (01799) shares are down more than 5%, trading at HK$4.42. XINYI SOLAR (00968) shares have fallen over 4% to HK$2.37. FUYAO GLASS (03606) shares are down more than 3.5% at HK$52.85, while FLAT GLASS (06865) shares have declined nearly 3% to HK$7.24.

Market Drivers and Analysis

The recent market movement follows news that the national standard "Energy Efficiency Limits and Grades for Crystalline Silicon Photovoltaic Modules and Inverters" has entered the final approval stage before release and is expected to be officially published shortly. There is market speculation that this could lead to the exit of up to 30% of production capacity. However, analysis suggests this may not significantly impact near-term supply and demand dynamics.

According to industry data, annual production capacity for photovoltaic modules has surpassed 1,000 GW. Production output for May was 36.36 GW, implying an operating rate of only around 35%. Furthermore, the majority of existing capacity is considered high-efficiency. Therefore, the phase-out of less efficient capacity is not anticipated to disrupt short-term supply-demand balances.

Broader Industry Outlook

Additional commentary from financial institutions paints a mixed picture for the sector's future. During the recent Shanghai SNEC solar exhibition, various companies showcased perovskite solar cell products designed for space applications. However, concerns regarding product reliability and the extended timeframe required to gather sufficient performance data from space environments suggest that commercial adoption in this niche may face significant hurdles and a slow pace of development.

Looking ahead, the demand outlook for the photovoltaic supply chain in 2026 appears subdued. This sentiment is partly attributed to China's planned transition from a feed-in tariff system to a market-oriented pricing mechanism scheduled for June 2025. Furthermore, the industry is bracing for intensified competition as new players continue to enter the already crowded photovoltaic module manufacturing space.
