24 x 430W Sharp NU-JC430B Full Black Monocrystalline Solar panel with high-efficiency TOPCon cells:

The twenty-four high efficiency solar panels use TOPCon technology with higher efficiency due to improved passivation and reduced recombination losses, better performance at high temperatures, and enhanced long-term stability. The half-cut cell construction decreases internal losses, reduces risk of hotspots and improves performance in shaded conditions. These MCS certified panels are perfect for a wide variety of applications, from grid-tie household systems to off-grid installations where mains power is limited or unavailable such as boats, caravans, campervans, cabins or glamping huts.
