JA 475W LR

The JA Solar JAM54D40-475/LR is a 475W n-type double glass monofacial solar module designed for residential and commercial rooftop applications. Its module efficiency of 23.8% and use of n-Bycium+ half-cell technology with 16 busbars ensure excellent energy yield and superior current collection. The panel's n-type cell architecture delivers very low light-induced degradation (LID) and a better temperature coefficient of -0.290%/°C, meaning it maintains stronger performance during hot weather compared to standard p-type panels.

The double glass construction with 1.6mm front and back glass provides enhanced durability and resistance to harsh environmental conditions, including front static loads of up to 5400 Pa and rear loads of up to 2400 Pa — making it well suited to Australian conditions. With 108 half-cut cells and an IP68-rated junction box, the panel is built for long-term reliability and low maintenance. Its better low irradiance response also ensures solid energy production on cloudy days.

JA Solar backs this panel with a 25-year product warranty and a 30-year linear power output warranty, with just 0.4% annual degradation after year one — guaranteeing strong long-term performance. With its combination of premium cell technology, robust build quality, and industry-leading warranty, the JAM54D40-475/LR is a compelling choice for homeowners and installers seeking a high-efficiency, reliable solar solution.
