2.1 Brief Introduction to the Market Environment for Vietnamese Buyers to Purchase Photovoltaic Modules

2.1.1 Core Characteristics of Vietnam's Photovoltaic Procurement Market

2.1.1.1 Diversified Procurement Needs

2.1.1.1.1 Diverse Scenario Needs

At present, Vietnam's photovoltaic procurement demand presents a diversified trend, including bulk component procurement for large-scale ground power stations and floating power stations, small and medium-sized procurement for residential and industrial/commercial rooftop distributed projects, and the gradual growth of procurement demand for characteristic projects such as agriculture-solar complementary and fishery-solar complementary. This requires buyers to choose brands that can provide diversified products to adapt to the needs of different project scenarios, and all the above 25 brands can cover various procurement scenarios.

2.1.1.1.2 Clear Procurement Focus

When choosing brands, Vietnamese buyers focus on four core points: first, product quality, which needs to meet international and local Vietnamese standards and adapt to Vietnam's climate characteristics; second, supply stability, to avoid project progress delays due to delayed delivery; third, localized services, including after-sales response and installation guidance, to reduce late operational risks; fourth, cost performance, to control procurement costs on the premise of ensuring quality. Especially in the current environment of rising component prices, stable quotations and high cost performance are more important.

2.1.1.2 Advantages of Procurement Environment

The Vietnamese government has long implemented clean energy support policies, with convenient approval for photovoltaic projects. At the same time, Vietnam is located in the core area of Southeast Asia, with convenient logistics and transportation, which can effectively shorten the component transportation cycle and reduce transportation costs. In addition, Vietnam has gathered production bases of many world-renowned photovoltaic brands, forming a sound photovoltaic supply chain. Vietnamese buyers can directly connect with local production bases to achieve rapid procurement and convenient after-sales service, without relying on imports, greatly reducing procurement costs and risks. At the same time, some local Vietnamese photovoltaic auxiliary material enterprises have also formed a scale, which can provide supporting services for buyers, further improving the procurement experience.

3.3 Core Suggestions for Vietnamese Buyers to Choose Solar Panel Brands

Combining the characteristics of Vietnam's procurement market and the core needs of buyers, it is recommended that Vietnamese buyers focus on three points when choosing solar panel brands: first, product adaptability, priority should be given to brands whose products can adapt to Vietnam's high temperature, high humidity and windy/rainy climate characteristics, to reduce the risk of late product attenuation and failure. For example, modules with salt spray resistance and humidity resistance are more suitable for projects in coastal and rainy areas of Vietnam; second, service convenience, priority should be given to brands with warehousing centers and after-sales service points in Vietnam that can provide Vietnamese language services to ensure timely delivery and rapid after-sales response; third, cooperation stability, choose brands with strong production strength and sound supply chains to avoid the impact of insufficient brand production capacity and supply chain fluctuations on procurement plans. Especially in the current context of industry capacity clearing and rising component prices, stable partners are more important.
