LONGi Solar
High-Efficiency Mono & TOPCon Solar Panels
LONGi Green Energy is the world's largest solar panel manufacturer, founded in Xi'an, China in 2000. Starting as a silicon wafer specialist, LONGi pioneered the shift to monocrystalline technology that now dominates the industry. Their Hi-MO series spans PERC, bifacial, and TOPCon technologies, consistently pushing efficiency boundaries. The Hi-MO X (HPBC) and Hi-MO 6 TOPCon panels have set world efficiency records. LONGi's manufacturing scale, financial strength, and R&D investment make them one of the most bankable panel brands in the world — widely used in Australian residential and commercial solar installations.
