Tokyo, Japan – Tokyo-based cleantech pioneer GBP K.K., known for its rapid growth across renewable energy, EV components, AI, and IoT sectors, has announced the launch of its new lightweight N-type TOPCon solar panel, the “GBP355T-88N.”

Weighing just 5.6kg/m² with an impressive conversion efficiency of 21.3% and robust durability, this panel is specifically designed for installation on low-load roofs. It opens new possibilities for older buildings or structures that previously could not support conventional solar systems due to weight constraints.

Specifications at a glance:

Model: GBP355T-88N
Dimensions: 2138 x 780 x 5 mm
Weight: 9.3 kg
Max Output: 355W
Efficiency: 21.3%
Cover Glass: 1.6mm tempered glass
Cell Type: N-type TOPCon half-cell
Certifications: IEC61730, IEC61215
Warranty: 10-year product warranty, 20-year performance guarantee

Key Features:

■ Ultra-lightweight for low-load rooftops
At approximately half the weight of standard modules, this panel can be installed on structures with limited load-bearing capacity—making solar possible for many buildings that were previously unsuitable. Despite its light weight, it still delivers a high efficiency of 21.3% using advanced N-type TOPCon cells.

■ Lower total cost, no structural reinforcement needed
The lightweight design allows installation without roof reinforcement in many cases, eliminating the need for additional structural design or construction work. This shortens project timelines and reduces upfront costs, making it an attractive option for older buildings and hard-to-modify sites.

■ Reinforced 1.6mm tempered glass for long-term durability
Despite its slim profile, the GBP355T-88N is built with 1.6mm tempered glass that provides high rigidity and resists deformation from environmental stress over time. Unlike conventional thin panels that can warp or accumulate dust, this model significantly reduces concerns around long-term wear and tear.

Ideal for:
- Factories, warehouses, parking lots, gymnasiums with seam-folded or ribbed metal roofs
- Older buildings with uncertain roof load-bearing capacity
- Projects seeking non-invasive, damage-free installation
- Government or corporate entities with limited installation timeframes or budgets
