Longi LR7-54HVH-490M

The LONGi LR7-54HVH from the Hi-MO X10 series achieves an efficiency of up to 24.5 % thanks to innovative HPBC 2.0 technology (Hybrid Passivated Back Contact). The full back-contact structure maximizes light absorption and increases energy yield. With a robust design made of tempered glass, high load capacity for snow and wind, and optimized temperature stability, this module is ideal for premium residential applications and offers a long service life.

• Module TechnologyHPBC 2.0 technology (Hybrid Passivated Back Contact) relies on a full back-contact structure with no visible busbars on the front. This maximizes light absorption and significantly increases efficiency. Thanks to optimized passivation and improved cell architecture, this technology offers higher energy yield, improved 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 LR7-54HVH offers up to 25 years of 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.
