Show series description

The AIKO Stellar 2N+78 series introduces a new quality to the utility-scale sector, utilizing pioneering All-Back Contact (ABC) technology, which completely eliminates energy losses resulting from front electrode shading. By moving all contacts to the back of the cell, these panels achieve unprecedented efficiency, which directly translates into higher energy yield from a smaller installation area. A key differentiator of the series is intelligent partial shading optimization, which allows the module to work efficiently even in challenging location conditions where traditional solutions lose a significant portion of their power. This breakthrough approach solves the problem of performance drops caused by dirt, leaves, or terrain obstacles. The design based on N-type cells guarantees minimal annual degradation, making this series an excellent choice for photovoltaic farms and commercial projects focused on maximizing long-term profits. Unique busbar-less aesthetics go hand in hand with extreme mechanical durability, clearly distinguishing these modules from standard panels available on the market. AIKO Stellar 2N+78 is a solution for investors seeking a technological advantage and the highest power density, redefining efficiency standards in modern solar energy.
