LONGi has launched its groundbreaking Hi-MO X6 bifacial dual-glass module at the 19th edition of China’s International Solar Energy Utilization conference in Jinan. The cutting-edge product line includes the ‘Explorer’ and ‘Guardian’ (anti humidity and heat) models, especially designed for high temperature and high humidity environments, representing a significant leap forward for the PV industry.
The Hi-MO X6 series is the latest example of the company’s consistent innovation in response to the evolving demands of the PV market, with over 40% of regions around the world classified as Damp Heat (DH) climates presenting substantial challenges for PV modules, ranging from leakage degradation to adhesive film yellowing and hydrolysis reaction.
The ‘Guardian’ model stands out for its exceptional resistance to humidity and heat, a critical advancement given the widespread need for durable and efficient solutions. LONGi’s dedicated “Anti Humidity and Heat Module” project team has been at the forefront of its development, introducing a series of technological advancements including:
- Busbar-free front side design for higher energy yield.
- Customized electrode paste to significantly enhance resistance to degradation in high humidity and high temperature environments.
- A highly water-resistant sealant solution, coupled with a high-quality adhesive film process to prevent intrusion of water vapour.
Compared to traditional TOPCon and PERC modules, the Guardian provides superior performance, including:
- Only 45% of TOPCon’s DH degradation, ensuring long-term stable power generation.
- Improved performance in high temperature and low irradiation conditions.
The bifacial dual-glass portfolio caters for a wide range of application scenarios, including distributed roofs, PV carports and winter gardens, the bifacial design allowing for efficient power generation by effectively utilizing light reflected to the rear side, providing additional power generation gains.
