LONGi Hi-MO 9 Module: Industry-First Full-Scenario Certification for Unmatched Reliability

Global News
2026.1.30

Recently, LONGi’s HPBC 2.0 module Hi-MO 9 successfully passed over 40 full-scenario test sequences for application environments including lakes, deserts, ice and snow, and marine areas, and was awarded the Full-Scenario Application Certificate based on the IEC 63556 standard by the National Quality Inspection and Testing Center for Solar Photovoltaic Products (CPVT) and Huaneng Clean Energy Research Institute(CERI). As the photovoltaic industry’s first certification for module "reliability across all scenarios", this certificate once again strongly proves the outstanding quality of Hi-MO 9 modules, which can maintain efficient and stable power generation even in complex and everchanging external environments.

It is understood that the "National Quality Preferred" Weather Resistance Test Certificate for Full Application Scenarios issued by CPVT and CERI is based on relevant IEC 63556 standards. It involves a comprehensive and rigorous series of simulated tests on the weather resistance of photovoltaic modules in various application environments such as ecological lakes, hot and arid deserts, polar ice and snow regions, and deep blue marine areas. Built on HPBC2.0 technology, LONGi Hi-MO 9 modules deliver exceptional performance in temperature control, low-light power generation and operational reliability. Thanks to their excellent power generation performance in various test scenarios, Hi-MO 9 modules have successfully won the industry’s first full-scenario application certificate.

To deliver greater life-cycle value to end customers, LONGi launched a systematic empirical program covering multiple key global markets simultaneously upon the launch of its BC flagship Hi-MO 9. This empirical network extensively covers a variety of typical and harsh environments including temperate continental climates, tropical regions, arid areas and high-humidity coastal lines, aiming to go beyond laboratory standard conditions and fully evaluate the performance of Hi-MO 9 in real operating environments. Data from global customers, authoritative third-party institutions and self-built empirical bases shows that Hi-MO 9 has demonstrated beyond-expectation stability and consistency in actual power generation performance, system economic benefits and environmental adaptability.

Data reports from a number of international authoritative technical service institutions consistently indicate that compared with the current mainstream TOPCon modules on the market, Hi-MO 9 achieves a stable increase in power generation per watt worldwide, with a gain range of 1.21% to 3.92%, and its performance is particularly outstanding in some scenarios.

The efficient and highly reliable power generation of Hi-MO 9 module throughout its life cycle will bring end users worldwide a better experience of value increment, and the high-quality BC product solution will also set a new technical benchmark for the industry. LONGi will continue to be customer-centric, keep deepening technological innovation, and drive the early realization of the green energy world dream with photovoltaic products featuring lower levelized cost of electricity (LCOE).
