High-alpine photovoltaics: Premium solar modules for extreme conditions

In high alpine regions, solar systems can generate up to 50 % of their annual yield in winter - significantly more than systems in the lowlands. This potential is enormously valuable for sustainable power supply, but brings with it extreme environmental conditions. Heavy snowfall, gale-force winds, severe temperature fluctuations and hail place the highest demands on photovoltaic modules in the mountains. SwissWatt One AG has accepted this challenge: With premium solar modules developed in Switzerland - above all the new Davos Diamond 2.0 model - we offer products that are specially designed for use in high alpine regions.

Graphene coating: more protection, less soiling

Another highlight of the Davos Diamond 2.0 is the innovative Graphene coating of the glass surface. This ultra-thin, transparent protective layer not only improves the scratch resistance and weather resistance of the modules, but also has a hydrophobic and self-cleaning effect. This means that snow, water and dust roll off more quickly, meaning that the modules get dirty less often and operate at maximum efficiency for longer. This is a decisive advantage, especially in high alpine locations with frequent snowfall and strong winds. The graphene coating not only extends the service life of the modules, but also reduces maintenance costs and contributes to long-term yield reliability.

Special requirements in an alpine environment

Photovoltaic systems at high altitudes are confronted with extreme snow and wind loads, icy temperatures down to -45°C and hailstorms. At the same time, they benefit from high solar intensity, reflection from snow and clear air. The conditions for a high solar yield are in place - provided the modules can withstand the stresses.

SwissWatt One Davos Diamond 2.0: Built for extreme conditions

The Davos Diamond 2.0 model was developed for such applications. With a temperature resistance of -45 to +88°C, mechanical load capacity of up to 8000 Pa and hail class 4, it meets the highest standards. The glass-glass construction and the anodized aluminium frame ensure robustness. The module can also withstand thermal loads caused by rapid temperature changes without any loss of performance.

Top performance thanks to bifacial TopCon technology

With a module efficiency of up to 23.04 % and N-type TopCon cells, the Davos Diamond 2.0 achieves a premium level of efficiency. The bifacial design enables additional energy generation through reflected light - particularly valuable in snow or bright surroundings. Depending on the albedo, additional yields of up to 30 % are realistic.

Longevity and guarantees

SwissWatt One AG grants a 40-year product and performance guarantee with a linear degradation of only 0.25 % p.a. In the event of a warranty claim, the module will be replaced with a current version free of charge. Electroluminescence tests ensure product quality before delivery.

Premium components and Swiss quality promise

MC4-EVO2 connectors from Stäubli, anti-reflective glass and a double-sided glass structure guarantee maximum reliability in the field. Developed in Switzerland, with customer service and warranty provider in Switzerland, the Davos Diamond 2.0 is a reliable building block for demanding solar projects in the premium segment.

Conclusion: Future-proof energy generation in the high mountains

For operators, planners and installers, the SwissWatt One Davos Diamond 2.0 offers the perfect combination of resistance, efficiency and guarantee. As a premium solar module, it is ideal for alpine locations and reliably delivers maximum yields even under the most extreme conditions.
