JA Solar

JA Solar is one of the largest panel manufacturers in the world, and the n-type modules we stock are the ones we fit ourselves on domestic and commercial roofs.

The range runs from 450W all black panels, which most people choose for a house roof because the frame and backsheet disappear against dark tiles, up to 600W bifacial modules that also generate from light reflected onto the rear face. Bifacial gain depends on what is under the array, so it earns its keep on a flat roof or ground mount with a light surface, and much less on a dark pitched roof.

Panels are sold singly, in packs of 12 and as full pallets of 36. Pallet pricing is better per panel, and pallets ship on a dedicated delivery rather than by parcel carrier.
