The 13th World Photovoltaic Fair ran alongside Canton Fair from 18-20 November 2021, booth V02/B703. With travel still difficult, the visitors who did arrive came with concentrated agendas, and our booth became a product tour rather than a sales pitch.

Integrated Solar Street Lights

The core range, from compact 20W units for lanes to 120W models for main roads. Visitors checked the all-in-one layout, the panel-to-battery matching and the bracket. The most common question was not about lumens but about installation time: how many units can a two-person crew mount in a day? With no trenching and a two-bolt bracket, the answer is usually 20 to 30.

Solar Garden Lights

Lower mounting heights, softer distribution and a focus on appearance. Buyers from residential projects compared pole-top and wall-mounted formats, and asked whether the panel could be angled toward the equator when the fixture is fixed to a wall.

Solar Billboard Lights

A niche product with a specific problem: illuminating a sign evenly without spill light into nearby windows. We demonstrated the asymmetric optic and the shielding option, which mattered to buyers in dense urban markets.

Solar Camera Lights

The 4G remote monitoring units attracted the longest stops. Buyers asked how the camera and light share power, what happens to recording when the battery is low, and whether the SIM can be swapped locally. These are the questions that decide whether a combined unit is genuinely useful or just two products in one box.

The Engineering Story

We used the booth to explain the parts buyers cannot see: battery thermal protection, housing sealing and light efficiency. African buyers asked about dust and rain, Middle East partners about heat, and Southeast Asian and South American visitors about cost-effective models for town roads and public security projects.

Why the Range Mattered

Buyers at this show were rebuilding supply chains after a disrupted two years. Many had been forced to buy whatever was available and were now dealing with the consequences: mismatched panels, undocumented batteries and lamps that could not be serviced.

Seeing four product families from one manufacturer, with shared service parts and consistent documentation, answered a question they had not asked out loud: can this supplier still be here in three years? A broad but coherent range is evidence of that.

Many visitors said the range matched their market almost exactly. That is not an accident. The product line was built from project feedback, and the fair was a chance to check whether the feedback still holds.
