JA Solar 465W N-type Double Glass Monofacial LR Traceable 54 Cell Black Frame MC4 Solar Panel
JA Solar 465W N-type Double Glass Monofacial LR Traceable 54 Cell Black Frame MC4 Solar Panel
The JA Solar JAM54D40 LR 465 W is an N-type mono solar panel. It delivers 23.3 % module efficiency from a 1,762 × 1,134 mm frame.
About the JA Solar Deep Blue 4.0 Pro range
Deep Blue 4.0 Pro is JA Solar's n-type platform, using Bycium+ cells with a better temperature coefficient, lower light-induced degradation and improved low-light behaviour than the p-type modules it replaces.
At 1,762 × 1,134 mm it is a residential-format module, sized to fit the rafter spans and roof planes of a standard UK house.
Why installers specify this panel
- −0.290 %/°C power temperature coefficient — output falls away more slowly as the modules heat up through the middle of the day.
- All-black appearance — a black anodised frame and dark cells, for domestic roofs where the array has to be discreet.
- 0 to +3 % power tolerance — every module is sorted to meet or beat its 465 W nameplate rating.
