How To Find a Reliable Chinese Solar Factory To Purchase Photovoltaic Panels?

Lock in the technology route

Trend of high-efficiency components: In 2024, the market share of N-type TOPCon components will exceed 45% (such as Trina Solar Tiger Neo series efficiency 25.6%), and the cost of HJT components (such as LONGi Green Energy HJT-4.0 efficiency 26.3%) will drop to below $0.32/W, so it is recommended to give priority.

Adaptation to sub-scenarios: Industrial and commercial projects can choose high-power components (such as JinkoSolar Tiger Pro 670W+), and household projects focus on lightweight components (such as Risen Energy 210R 430W).

Regional capacity layout

Industrial cluster advantages: Jiangsu (Trina Solar, Canadian Solar), Zhejiang (Chint New Energy), Anhui (JA Solar) and other places have mature supply chains, and the delivery cycle is 15-20 days shorter than other regions.

Export convenience: Choosing factories in the Yangtze River Delta/Pearl River Delta can reduce the cost of shipping to European and American ports (e.g., about $150/m3 from Shanghai Port to Rotterdam Port).

Core certification verification

Target market access: The EU requires CE+IEC 61215+IEC 61730, the United States requires UL 1703+FTC certification, and Japan requires JET+MHLW certification.

ESG compliance: Pay attention to whether the factory has passed ISO 14001 (environmental management) and SA8000 (social responsibility) certification to avoid supply chain ESG risks.

Industry authority endorsement

Ministry of Industry and Information Technology white list: Enterprises selected in the "photovoltaic manufacturing industry standard conditions" (such as Tongwei Co., Ltd. and GCL Integration) enjoy priority channels for export tax rebates.

Third-party rating: Refer to PV Magazine's "Global Module Brand Bankability" ranking (top three in 2024: LONGi, JinkoSolar, and Trina Solar).

Key parameter benchmarking

Material and process verification

Glass: The life of 3.2mm double-glass modules is extended to 30 years (such as JA Solar DeepBlue 4.0).

Packaging materials: The cross-linking degree of EVA film is required to be ≥85%, and the backplane adopts polyvinyl fluoride (PVF) lamination technology.

Test standards: The factory is required to provide salt spray test (IEC 61701) and damp heat test (IEC 61215) reports from third-party laboratories.

Production and delivery guarantee

Capacity transparency: Require factories to provide monthly capacity reports (such as Tongwei Solar's silicon material capacity of 250,000 tons in 2024).

Logistics plan: Give priority to factories that have signed long-term agreements with Maersk and COSCO Shipping to ensure peak season space.

Payment and risk control

Payment terms: Adopt the letter of credit (LC) + advance payment guarantee model, and it is recommended to pay in stages (30% advance payment + 60% see bill of lading + 10% warranty).

Exchange rate hedging: Negotiate with the factory for USD/EUR settlement, or sign exchange rate floating terms.

Online procurement channels

Vertical platform: Screen "Gold Supplier" certified companies (such as JinkoSolar and Suntech Power) in the Global Sources photovoltaic area.

Digital exhibition: Participate in the Virtual SNEC online exhibition and directly connect with the technical team (support multi-language services).

Localized service support

Technical response: Require the factory to provide technical documentation in English/Spanish and 24-hour remote support.

After-sales network: Choose companies with local warehouses in the target market (such as Trina Solar, which has spare parts centers in 10 European countries).

Intellectual property protection

Check the factory's patent layout (such as LONGi Green Energy holds 1,200+ photovoltaic patents) to avoid infringement lawsuits in the importing country.

Compliance review

Screen the supply chain through the U.S. Customs "withholding order" database (WRO List) to ensure that Xinjiang silicon materials are not used.
