Longi LR7-54HVBB-480M

The LONGi LR7-54HVBB is a bifacial dual-glass module from the Hi-MO X10 series featuring HPBC 2.0 cell technology, achieving an efficiency of up to 23.8 %. It offers an elegant, all-black design without visible busbars, combined with high mechanical load capacity and an optimized temperature coefficient for maximum yields even under demanding conditions.

• Module TechnologyHPBC 2.0 technology (Hybrid Passivated Back Contact) utilizes a complete back-contact structure with no visible busbars on the front, maximizing light absorption and significantly increasing efficiency. Through optimized passivation and improved cell architecture, it offers higher energy yield, better temperature stability, and a longer service life compared to conventional cell technologies.
• QualityAt LONGi Solar, quality is the top priority. In addition to complying with IEC 61215 and IEC 61730 standards, LONGi goes one step further: testing is conducted with triple the standard testing times. Specifically, this means that the Damp Heat Test lasts 3,000 hours instead of only 1,000 hours. This extra effort ensures that the modules reliably meet the requirements of the standards throughout their entire life cycle.
• SustainabilityLONGi modules represent true sustainability: their high efficiency and long service life lower energy consumption and reduce CO₂ emissions over the entire life cycle. Manufactured from robust, recyclable materials, they support the circular economy and minimize the ecological footprint of photovoltaic production – for environmentally friendly and future-proof energy generation.
• WarrantyThe LONGi LR7-54HVBB features a 30-year product warranty covering material and workmanship defects, as well as a 30-year linear performance warranty, guaranteeing at least 99 % of the nominal power in the first year and approximately 87 % after 30 years. These warranties apply when professionally installed and in compliance with the manufacturer's terms and conditions.
