A new altitude record has just been broken at Everestan extreme and privileged environment in which it is essential take care of the environment and in which it was possible for zero-emission vehicles can be recharged in a solar station at an altitude of over 4,300 meters above sea level.
Innovation and technology have come together on the roof of the world in Everest National Park, taking a giant, sustainable step forward in successfully feeding the world’s tallest solar charging station.
The challenge of overcoming this altitude barrier was made possible by the incorporation of Aiko’s N-type ABC solar modules, which, combined with Huawei Digital Power’s liquid cooling technology, have successfully set a new standard for green energy solutions in extreme environments.
Charging station on Everest
For the Aiko company, “a giant step has been taken in terms of sustainable development” by successfully participating in this project. New step in the power supply of the Everest charging station.
This new installation is part of the project Green Corridor Supercharged by Sichuan-Tibet Expressway (Green Corridor Supercharged by Sichuan-Tibet Expressway) along national road 318.
The corridor in which they travel more than a million tourists each yearsolves the problem of lack of autonomy for electric vehicle owners who venture into this high-altitude area known for its spectacular landscapes, but with limited charging infrastructure.
A hostile environment
The project overcame the many challenges posed by this type of facility at this altitude and in an environment that is not very favourable to its operation. These obstacles are really significant, since the bad weatherHailstorms and blizzards with powerful winds, combined with high levels of solar radiation, make the environment completely unpredictable.
In addition, altitude, intense cold and snow loads pose serious risks to any solar system. In this challenging context, Aiko’s N-type ABC modules were selected for their micro-tear resistancehigh efficiency and great performance both in high UVA exposure and at low temperatures.
Most extreme conditions
To cope with unpredictable weather conditions, solar modules are capable of withstand extreme temperature differences up to 40℃ and heavy hailstorms.
So far, their drivers confirm that they have passed IEC HF reliability and performance tests up to 4 times. hailobtaining PVEL certification with 50 mm hailstones.
Another big challenge is overcoming the high altitude and UV exposure. The location suffers from areas with high UV exposure. ultraviolet radiation They can cause deterioration of the encapsulant of the modules. In this sense, the Aiko company has passed the IEC UV reliability tests four times, guaranteeing the longevity of its modules in these conditions.
Against wind and snow
At this altitude, logistical and installation challenges must be overcome in harsh environments, such as wind gusts and snow loadswhich affects its durability. After installation, the ABC modules obtained excellent results in the DML+TC reliability tests, with reliability and resistance to micro-breaks.
To minimize the effects of partial shading and reduce hot spot temperatures, a key feature in rugged mountain terrain, these modules are optimized to overcome what is known as “hot spot effect“, providing greater safety against fires.
No more electricity
As altitude increases, air density and atmospheric pressure decrease, thereby weakening the atmosphere. insulating properties in solar modules. Thanks to the insulation properties, Aiko has passed the IEC high voltage test 1.5 times to ensure its performance at these altitudes.
And despite all the unfavorable conditions for the installation of solar charging infrastructure for electric vehicles, the ABC modules were able to generate 6 to 10% more electricity per square meter maximizing production in areas where there is no electricity.
A sustainable future in remote areas
This project illustrates Aiko’s mission to also bring clean energy to places the most remote and deserted place on the planetBy generating 236,800 kWh of clean energy per year, the Everest charging station reduces the carbon footprint caused by travel to this iconic region.
This spirit is complemented by the company’s vision of a society emission-free so that development and environmental protection can coexist peacefully.
