What's Included
The LONGi Hi-MO X10 475WP Solar PV Panel is built on the strengths of HPBC 2.0 technology and takes things further with a refined back-contact (BC) design that removes grid lines from the front of the cell. This cleaner layout is paired with upgrades across the board, including improved cell substrates, hybrid passivation, and more advanced manufacturing processes. The result is a clear step up from standard cells, with noticeable gains in performance, reliability, and overall functionality.
Higher Efficiency, More Output
Using N-Type HPBC 2.0 cell technology, these modules reach up to 23.5% efficiency, helping you generate more energy from every square metre. With a power output of 475W, they make better use of available space, which is especially useful on rooftops where every panel counts.
Strong Performance in Partial Shade
Shading can be a real issue with solar, but the built-in shading optimiser helps reduce its impact. Thanks to a “soft breakdown” design, current can flow around shaded cells instead of stopping altogether, which means the panel can retain around 92% of its output even in partial shade, cutting power loss by more than 70% compared to conventional panels.
Built for Reliability
Durability starts at the core - new TaiRay wafers increase break resistance by 16%, helping to reduce the risk of micro-cracks during transport, installation, and everyday use by up to 87.2%. On top of that, enhanced POE encapsulation provides added protection against moisture and UV exposure, supporting long-term performance.
Performs Well in Heat
With a low temperature coefficient of -0.26%/°C, these panels continue to perform efficiently even in warmer conditions. Compared to standard TOPCon modules, they maintain a higher energy yield when temperatures rise.
Designed for Tough Conditions
These modules are made to handle challenging environments, withstanding snow loads of up to 5400Pa and wind pressures of up to 2400Pa. The design also helps prevent localised overheating, improving both safety and long-term stability.
Long-Term Peace of Mind
You’re covered with a 25-year product warranty and a 30-year linear power output warranty, so even after three decades, the panels are guaranteed to deliver at least 88.85% of their original output. And degradation is kept low, with less than 1.5% in the first year and just 0.35% annually after that, helping ensure a steady return over time.
Full Traceability and Transparency
With full SDM1 traceability, every stage can be tracked, from raw materials through to installation. This level of transparency supports stronger project oversight and aligns with growing ESG expectations.
Flexible and Future-Ready
The compact 54-cell format and high-voltage capability make these panels suitable for a wide range of uses, from residential rooftops to commercial and architectural projects. It’s a flexible solution that fits neatly into modern energy systems.
