The Unisun 55.12BC solar panel, with back contact technology, has the entire cell surface to capture light energy (electrical contact at the back of the cells). At equal power, thanks to its greater efficiency (power/surface ratio), Unisun 55.12BC offers the advantage of being more compact than a standard rigid panel (contact on the front face of the cells) and is therefore ideal for applications where size or weight are selection criteria.
Modular, for more power, its connection in series or parallel is made easier thanks to its fast solar connectivity.
