Dust and Sand Test Chamber

Trina Solar and Yuexin Sign Cooperation Agreement

As a company in the photovoltaic sector, LONGi Solar maintains extremely stringent quality control over solar PV‑power‑plant equipment. During operation, such equipment is exposed to a range of harsh environmental conditions, including the impact of sand and dust on photovoltaic modules. To ensure that PV‑power‑plant systems can operate reliably and stably over the long term in desert or desertified environments, conducting dust‑resistance testing is of paramount importance.

The Yuexin Sand and Dust Test Chamber is a testing device used to simulate sandy and dusty environments and evaluate the dust‑resistance performance of photovoltaic modules. By employing this chamber, LONGi Solar can conduct rigorous dust‑proof assessments of its photovoltaic power‑station equipment, ensuring that it maintains robust dust‑resistance in real‑world applications.

During sand and dust testing, Dust and Sand Test Chamber The interior will be filled with sand and dust particles of a specific particle size, simulating a sandstorm environment. During the test, the sample is exposed to an airflow containing these particles, and a horizontal airflow circulation is used to replicate the impact and erosion of sand and dust on the surface of photovoltaic modules. The testing standards typically follow GB/T 4208 or IEC. 60529 International and national standards, which specify the detailed parameters for sand and dust testing—such as sand and dust composition, particle size, density, test wind speed, temperature and humidity conditions, and test duration—are in place.

Through Yue Xin Dust and Sand Test Chamber Through rigorous testing, LONGi Solar ensures that its photovoltaic power‑plant equipment meets stringent dust‑proof performance standards during both design and manufacturing. This enables reliable, efficient energy generation in sandy environments such as deserts, while also contributing to the sustainable development of the global photovoltaic industry.
