WELONS GROUP CO.,LIMITED

Welons is a manufacturing and trading company based in Guangzhou, China, focused on supplying photovoltaic panels and architectural glass to overseas markets. We work across product design, production, quality inspection, export logistics, and after-sales coordination, helping customers simplify their sourcing process.

Our product range covers:

• Photovoltaic panels: Standard and flexible solar panels in various power ratings, as well as custom BIPV glass panels for building facades
• Architectural glass: Tempered glass, laminated safety glass, Low-E insulated glass, and decorative colored glass used in curtain walls, windows, and building exteriors

These products are supplied to contractors, distributors, and project developers working on commercial buildings, residential developments, and industrial facilities.

We currently have an established presence in the Philippines market, where our products have been used in hospital renovation, commercial building, and off-grid power projects. We are gradually expanding to other Southeast Asian and overseas markets, focusing on reliable quality, flexible order quantities, and responsive communication rather than large-scale branding.

Our goal is to be a practical, dependable supplier that overseas customers can work with long term—whether for one-off sample orders, regular bulk purchases, or customized project requirements.

2015 - Company Founded

Welons was founded in Guangzhou, China in 2015, initially focused on building materials export to Southeast Asian markets. In the early years, we worked closely with local distributors and project contractors to understand market needs and build reliable supply chains.

2015-2022 - Steady Growth in Southeast Asia

Over the first several years, we built our presence in the Philippines and neighboring Southeast Asian markets, supplying building materials to commercial and residential projects. Through hands-on project experience, we developed practical knowledge of local climate conditions, installation requirements, and customer expectations.

2023-2024 - Expansion into Renewable Energy

Seeing growing demand for solar and energy storage products, we began expanding our product range to include photovoltaic panels, inverters, and battery storage systems. We started with sourcing and in-house testing, working closely with component suppliers to ensure quality and performance.

2025 - Own Production Facility

In 2025, we moved into our own manufacturing base in Guangzhou, covering glass processing, solar panel assembly, and inverter/battery integration. This allowed us to better control quality, lead times, and customization for overseas customers.

Guangzhou Team

Based at our factory in Guangzhou, this team handles production planning, quality control, and custom manufacturing. They work directly with the production floor to ensure orders are made to specification and shipped on time. This team also manages export documentation and shipping arrangements.

Our Hong Kong office handles international trade coordination and customer communication. They serve as a central point for inquiries, order follow-up, and after-sales support, helping overseas clients communicate efficiently with the factory.

We have local team members in the Philippines who support customers on the ground. They conduct site visits, verify project conditions, handle goods receiving and inspection at the port, and provide local coordination for installation and after-sales service. This local presence helps us understand on-site needs and respond quickly to customer issues.

Together, these three teams cover production, trade, and local service—allowing us to support overseas customers not just with products, but with practical on-the-ground support throughout the project.
