Longi LR7-54HJD-505M

The LONGi LR7‑54HJD is a bifacial glass-glass photovoltaic module featuring 108 HBC N-type cells in a 6×18 layout, achieving peak outputs of 495–510 Wp with a module efficiency of up to 25 %. The dual-glass structure combined with specialized butyl sealing techniques ensures high reliability, improved safety, and environmental suitability. With a mechanical load capacity of 6,000 Pa on the front and 3,600 Pa on the back, the module is exceptionally robust and ideal for demanding installations.

• Module TechnologyThe LONGi LR7‑54HJD utilizes HBC N-type cell technology (Hybrid Passivated Back Contact), which enables extremely high efficiencies and low degradation through a full back-contact structure and optimized passivation. Additionally, the glass-glass construction provides enhanced durability, higher mechanical load capacity, and better protection against environmental influences.
• 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 LR7‑54HJD offers a 30-year product and performance warranty, which provides for an initial degradation of less than 1 % and a maximum annual degradation of 0.35 %. This ensures that at least 88.85 % of the original nominal power remains available after 30 years – for long-term reliability and stable yields.
