Advanced Design & HPBC 2.0 Technology

The LONGi X10 LR7-54HVD Dual Glass Solar Panel combines industry-leading performance, exceptional durability, and premium aesthetics in one of the most advanced residential solar panels available today. The X10 features next-generation HPBC 2.0 (Hybrid Passivated Back Contact) technology. Unlike conventional solar cells that place electrical contacts and busbars on the front of the cell, HPBC 2.0 moves them entirely to the rear.

This allows more sunlight to reach the active surface of the cell, improving efficiency while creating a sleek, uninterrupted all-black appearance. The result is higher energy yield, improved reliability, and industry-leading performance in real-world conditions.

Key Benefits

Superior Shade Performance

Partial shading from trees, aerials, vents, neighbouring buildings, leaves, or bird droppings can significantly reduce the output of traditional solar panels. HPBC 2.0 technology is engineered to minimise these losses, helping maintain higher energy production when shading occurs while reducing hotspot formation and thermal stress.

More Energy, Year After Year

The LONGi X10 is designed for exceptional long-term performance, with less than 1% degradation in the first year and only 0.35% annual degradation thereafter. This means more energy production over the life of your system.

Built for Australian Conditions

With an excellent temperature coefficient of -0.26%/°C, the X10 maintains strong performance even during hot Australian summers when many solar panels experience greater output losses.

Dual Glass Durability

Featuring a robust 2.0mm tempered glass front sheet and 1.6mm glass rear sheet, the LONGi X10 is engineered for exceptional strength, reliability, and long-term performance. Unlike conventional glass & plastic backsheet panels, the dual-glass construction provides superior resistance to moisture ingress, corrosion, UV exposure, and harsh environmental conditions. The result is improved durability, lower degradation, and greater long-term energy production, helping ensure reliable operation and peace of mind for decades to come.

Bifacial Power Generation

The longi panels can generate power from both the front and rear of the panel 

Premium Aesthetics

With no visible front-side busbars, the X10 delivers a clean, modern appearance that looks great on any roof.
