High-Efficiency PV Modules
HJ-B1-520W
HJ-B1-520W
1.8 mm thick, 2.9 kg/m², bends to a 0.3 m radius — the world's first 520 W hail-resistant, micro-crack-free flexible crystalline silicon module.
The roofs that most need photovoltaics are the ones that cannot carry it. Colour steel tile, glazed tile and older industrial decks were never engineered for 11 kg/m² of glass, and the structural retrofit costs more than the array it would support.
The HJ-B1-520W removes the constraint instead of engineering around it. At 1.8 mm and 2.9 kg/m² it weighs less than 30% of a conventional glass module, and it is fixed with structural adhesive — no drilling, no hot work, no penetration of the roof membrane.
Why this one
- 2.9 kg/m² and 1.8 mm thickUnder 30% of the weight of a traditional glass module, which changes transport, handling and installation as much as it changes the structural calculation.
- Bends to a minimum radius of 0.3 mAdapts to curved and irregular installation surfaces that a rigid laminate cannot follow.
- Nanofiber reinforcement five times stronger than steelSelf-developed high-strength material. Withstands 25 mm diameter hail at 82.8 km/h with degradation under one fifth of the international standard limit, and endures stepping and vehicle pressure.
- ≥20% efficiency on module active areaFirst-year degradation ≤2.5%, then ≤0.5% a year, holding ≥85% efficiency after 25 years.
- Adhesive fixing, no roof damageSuitable for low-load roof types such as colour steel tile and glazed tile, cutting construction time, installation cost and complexity.
- Built to be looked atCustomised installation to suit the architecture, for genuine building-integrated photovoltaics rather than panels bolted onto a building.

Questions about HJ-B1-520W
How is it fixed to the roof?
With structural adhesive. No drilling, no hot work and no roof penetration, which is why it can go on an operating plant without voiding the roof warranty.
Will it survive hail?
It is tested against 25 mm diameter hail at 82.8 km/h, with power degradation less than one fifth of the international standard limit, and it is described as micro-crack free.
What happens to output over 25 years?
First-year degradation is ≤2.5%, followed by ≤0.5% a year, maintaining ≥85% of efficiency after 25 years.
