China's change in export policy leads to an upward trend in solar prices.

  • OTHER

On January 9, 2026, the Chinese Ministry of Finance and the State Taxation Administration announced adjustments to the export tax rebate policy for solar-related products. Starting from April 1, the value-added tax export rebate for solar modules will be completely abolished, and the rebate for battery products will be gradually reduced, with a complete elimination expected by 2027. This policy will significantly change the export cost structure for Chinese manufacturers. Industry estimates suggest that the profit per mainstream 210-size module will decrease by approximately 1,050 to 1,160 yen, and for exports worth about 22.8 million yen, the previous rebate of around 2.05 million yen will disappear, resulting in an effective cost increase of about 9%. Additionally, raw material prices continue to rise. The prices of polycrystalline silicon and silicon wafers have recently increased by about 8 to 10%, and the price of battery cells has reached over 0.4 yuan/W (approximately 9.1 yen/W). Silver prices have also risen to over 19,000 yuan/kg (approximately 433,000 yen), pushing up module costs. Given this background, the cost increase due to the abolition of the export tax rebate is likely to be passed on to product prices. It should be noted that this policy will apply based on the export customs clearance date, so products cleared before April 1 will still be eligible for the previous rebate rate. (1 yuan ≈ 22.8 yen)

LONGi announced the "Climate Change Mitigation White Paper" and the first "TNFD Report" at COP30.

  • COMPANY

LONGi, a company that globally deploys solar power generation technology, announced the "2024-2025 Climate Change Mitigation White Paper" and its first TNFD (Taskforce on Nature-related Financial Disclosures) report at COP30 (the 30th United Nations Climate Change Conference of the Parties) held in Belém, Brazil. This white paper organizes efforts for decarbonization and medium- to long-term strategies across the entire value chain, from research and development to manufacturing, logistics, and product use. LONGi has set a medium-term goal of reducing Scope 1 and 2 emissions by 60% compared to 2020 levels and reducing Scope 3 emissions per unit by 52% by 2030, positioning the achievement of net zero by 2050 as a long-term goal. Additionally, the TNFD report, which is being published for the first time, analyzes the relationship with natural capital such as forests, water resources, and biodiversity based on the LEAP approach. It clearly states its commitment to reflecting nature-related risks and opportunities in management strategies and governance. LONGi aims to continue balancing climate change measures and nature conservation, contributing to the realization of a sustainable energy society.
