JA Solar JAM54S30-405/MR 405W Mono Black Frame Solar Panel 405 W monocrystalline panel with high module efficiency, ideal for commercial and industrial rooftop and ground-mount systems. Half-cell PERC design for improved performance in high temperatures and partial shading. Compact 108-cell format with black frame for neat, professional installations on warehouses, depots and logistics hubs. The JA Solar JAM54S30-405/MR 405W mono black frame solar panel is a high-efficiency module from JA Solar’s Deep Blue 3.0 range, well suited to UK commercial, industrial and logistics applications. Its 108 half-cell monocrystalline PERC layout delivers solid energy yield in a compact footprint, making it a good fit for rooftops where space and weight matter. Pair it with inverters and mounting from Energian for a robust, low-maintenance PV system backed by UK-based expert support. Key features Rated power output of 405 W with module efficiency around 20.7%, helping maximise energy generation per square metre. 108-cell mono PERC half-cell construction for better shade tolerance and lower internal losses. Black frame aesthetic, suitable for visible commercial rooflines and mixed-use buildings. 1500 V DC maximum system voltage for flexible string design in larger arrays. Designed for standard framed mounting systems used on flat and pitched commercial roofs and ground-mount structures.
