AIKO has received GB 3836.3 explosion protection certification for its ABC Stellar 66-cell dual-glass BC module from TÜV SÜD
The BC module uses copper-based cell-to-cell interconnection technology, reducing the potential for microcrack formation
Its exclusive thermal management design limits the hotspot temperature of the module
Leading back contact (BC) manufacturer AIKO Solar has announced that its ABC Stellar 66-cell dual-glass module has received explosion protection certification from TÜV SÜD. This certification verifies the module’s suitability for use in environments classified as explosion-hazardous, including oil and gas facilities, chemical plants, and fuel distribution infrastructure.
According to the company, this module is designed in accordance with the principles of ‘increased safety’ protection (Ex e) as defined under China’s GB 3836.3 explosion protection standard in line with the IEC 60079-7 framework. This approach focuses on eliminating ignition risks through enhanced insulation, increased electrical clearances (e.g., creepage distance), and strict temperature control to prevent the risks of electric arc or excessive surface temperatures during normal operation.
The company says this ABC (all back contact) module incorporates a structural and electrical design that is intended to minimize mechanical and thermal stress. Its BC cell architecture with both positive and negative electrodes on the rear side, combined with cell-to-cell copper-based metallization interconnection technology, eliminates conventional Z-shaped solder joints, which are typically prone to microcrack formation and pose long-term reliability risks. The design aims to maintain stable electrical performance and structural integrity by reducing these stress concentrations under demanding operating conditions. The module also features thermal management characteristics that limit localized temperature increases and reduce the potential risk of hotspot formation. These factors contribute to long-term operational stability and safety, particularly in volatile environments where temperature control and electrical reliability are critical.
AIKO cites compliance barriers created by the overlap between the revised Energy Performance of Buildings Directive (EPBD), and the ATEX directives in Europe. The former regulatory framework encourages broader solar integration, while the latter governs the use of equipment in hazardous environments. According to the company, this new certification may address this constraint for industrial operators seeking to expand on-site renewable energy generation while maintaining safety standards.
