Technologies used
High-efficiency TOPCon cells
TORRI modules use the latest-generation N-Type TOPCon (Tunnel Oxide Passivated Contact) cells.
TOPCon technology introduces a very thin layer of silicon oxide and a passivated polycrystalline silicon contact on the back of the cell, reducing charge carrier recombination and therefore internal electrical losses.
Compared with previous PERC technologies, it allows higher conversion efficiency, better behaviour at high temperatures, greater response in low-irradiance conditions and less degradation over time.
ARC — Anti-Reflective Coating
The front glass is treated with a nanostructured ARC anti-reflective coating, designed to increase the transmittance of solar radiation towards the cells.
The coating creates a layer with a refractive index intermediate between air and glass, reducing the index jump at the interface and therefore the optical losses due to reflection according to Fresnel's laws.
The structure and optical thickness of the coating are also designed to generate destructive interference between the components of reflected light, further decreasing reflectance at the wavelengths relevant to photovoltaic conversion.
The result is greater solar transmittance of the glass and an increase in the photon flux incident on the cells, with a reduction in the module's optical losses.

Hail resistance — IEC 61215 MQT 17
The hail resistance of a photovoltaic module is verified through controlled impact tests in accordance with IEC 61215-2 – MQT 17 Hail Test.
The test uses ice balls of defined diameter and mass, accelerated to a preset speed and directed at specific points of the module. It therefore evaluates not only the size of the hailstone: the fundamental physical parameter is the kinetic energy transferred during impact, determined by mass and, above all, by the square of the speed:
Test levels and impact energy
| Diameter | Mass | Speed | Kinetic energy |
|---|---|---|---|
| 25 mm | 7,5 g | 23,0 m/s | ≈ 2,0 J |
| 35 mm | 20,7 g | 27,2 m/s | ≈ 7,7 J |
| 45 mm | 43,9 g | 30,7 m/s | ≈ 20,7 J |
| 55 mm | 80,2 g | 33,9 m/s | ≈ 46,1 J |
| 65 mm | 132 g | 36,7 m/s | ≈ 88,9 J |
| 75 mm | 203 g | 39,5 m/s | ≈ 158 J |
Why impact energy matters
The base level of 25 mm subjects the module to about 2 Joules. As the hailstone diameter increases, the rise in severity is not linear: a 55 mm ball reaches about 46 Joules, over 23 times the kinetic energy of the 25 mm test. With a 75 mm ball it reaches about 158 Joules, almost 80 times the energy of the base level.
For this reason, knowing only the diameter of the hail is not enough to assess a module's resistance: diameter, mass, speed and impact energy must be considered together.
What is stressed during impact
The impact does not affect the glass alone. The energy is transferred through the entire module structure and can cause:
- —breakage or damage to the front glass
- —microcracks and cell fractures
- —damage to the interconnections
- —local deformation of the laminate
- —loss of insulation or deterioration of the electrical characteristics
This is why TORRI works on the module's resistance as a complete system: 4 mm front glass, laminate structure, high-density encapsulation and mechanical protection of the cells all contribute to the panel's ability to dissipate the energy generated by the impact.
Hail resistance is therefore not just glass resistance: it is the resistance of the entire architecture of the photovoltaic module.
