LONGi Hi-MO X10 EcoLife 485 Wp HPBC 2.0 Double Glass Full Black Solar Panel LR7-54HVBB-485

LONGi Hi-MO X10 EcoLife 485 Wp HPBC 2.0 Double Glass Full Black Solar Panel LR7-54HVBB-485

The LONGi Hi-MO X10 EcoLife is a high-quality Full Black double glass solar panel (glass-glass) of the latest generation, based on the innovative HPBC 2.0 technology – LONGi's most advanced back contact cell technology. This enables an exceptionally high output of 485 watts and a module efficiency of up to 23.8 % – one of the highest values in the Full Black double glass segment. Thanks to the fully black design with no visible gridlines, the panel blends aesthetically and unobtrusively into any roof.

The panel is built with a robust double glass construction (glass-glass) – with a 2.0 mm front and a 1.6 mm rear pane of semi-tempered glass. This protects the panel significantly better against moisture, UV radiation and mechanical stress – resulting in a considerably longer service life than conventional panels.

The LONGi Hi-MO X10 EcoLife is explicitly designed as a premium solution for high-end residential buildings and single-family homes. LONGi is consistently certified as a BloombergNEF Tier 1 manufacturer – one of the most prestigious recognitions in the solar industry for quality, bankability and reliability. Thanks to an optimised temperature coefficient of just −0.26 %/°C, the panel maintains its output even in summer. With a 30-year product warranty and a 30-year linear performance warranty, as well as a guaranteed output of at least 88.85 % after 30 years, performance remains exceptionally stable throughout the entire service life.

What is HPBC 2.0 & Back Contact Technology?

HPBC 2.0 stands for High Performance Back Contact 2.0 – LONGi's advancement of back contact cell technology. In conventional solar panels, electrical contacts run visibly across the front surface of the cell. In a back contact module, all contacts are fully relocated to the rear side – leaving the entire front surface available for uninterrupted light absorption. The result: higher power generation in all lighting scenarios, optimised anti-shading protection and the avoidance of localised overheating – for greater safety and longevity.

What Does Pure Black / No Gridlines Mean?

The LONGi Hi-MO X10 EcoLife impresses not only technically but also visually: as a Pure Black panel, all visible components – cells, frame and surface – are fully black. The standout feature: thanks to the back contact architecture, no busbars or conductive lines are visible on the front surface – no gridlines, no glare. The result is a flawlessly black, uniform surface that integrates seamlessly into modern roof architecture – aesthetic, unobtrusive and without any compromise on performance.
