650W LONGi Hi-MO Bifacial Glass-Glass Solar Panel with HPBC 2.0 Cell Technology

are proud to present this advanced 650W bifacial solar panel from LONGi – the Hi-MO X10 series – featuring proprietary next-generation HPBC 2.0 back-contact cell technology and the cutting-edge TaiRay Wafer for enhanced performance, strength, and longevity.

LONGi is a global leader in solar technology, providing reliable, high-performance energy solutions to drive the global energy transition. Through advanced solar and hydrogen technologies, LONGi is at the forefront of the shift to net zero-carbon energy systems – setting new industry benchmarks in solar panel innovation, efficiency, and durability.

LONGi’s HPBC 2.0 (Hybrid Passivated Back Contact) technology extracts more power from every ray of sunlight. By eliminating front-side busbars and integrating the innovative TaiRay Wafer, this panel achieves enhanced efficiency, improved heat resistance, and significantly extended lifespan – even in harsh climates or high-temperature environments.

Bipolar Hybrid Passivation boosts cell voltage, delivering increased energy output and minimising losses across the entire module. Combined with the zero-busbar (0BB) design, which eliminates shading from busbars and mechanical stress, the result is not only a sleek, modern appearance but also maximum energy harvest and superior long-term durability .

The bifacial glass-glass construction captures light from both sides of the panel, increasing yield by harnessing reflected sunlight. This makes it ideal for bright environments such as rooftops, commercial flat arrays, and off-grid applications. With high cell efficiency, these modules start generating earlier and continue producing later in the day, delivering more energy when compared to conventional solar panels – including in low light or overcast conditions.

LONGi’s TaiRay Wafers are engineered for structural integrity with a 16% higher bending strength than conventional wafers and up to 80% fewer hidden microcracks, ensuring better resilience and reliability over the lifetime of the system.

With a temperature coefficient of just -0.26%/°C, the Hi-MO X10 panel maintains strong performance even under high heat. Compared to TOPCon modules which have a coefficient of -0.30%/°C, this allows for greater power output in hot conditions and helping you save money, maximise space, and take a major step toward energy independence.

This MCS certified panel features a market-leading anti-shading performance which allows the power output to be maintained in changing light conditions. It is perfect for a wide variety of applications, from grid-tie household systems to off-grid installations where mains power is limited or unavailable such as boats, caravans, campervans, cabins or glamping huts. These high-power panels are ideal for large systems where the time and expense of fitting a high wattage array needs to be minimised.

This module is IP68 rated for waterproofing and rigorously tested against PID, salt mist, ammonia, dust, sand, and snow. Pre-installed MC4 connectors ensure quick, secure installation into any compatible solar setup.

With up to a 25-year product warranty and a 30-year power output guarantee, the LONGi Hi-MO X10 delivers outstanding long-term performance and peace of mind.
