Show series description

The MY Solar Half Cell series redefines performance standards through the use of advanced half-cut cell technology. The use of half-cut cells allows for a significant reduction in energy losses resulting from internal resistance, which directly translates into higher yields from the installation even in less favorable weather conditions. These panels deal perfectly with the common problem of partial shading. Thanks to the physical division of the module into two independent sections, shading one part does not completely block energy production, which is crucial on roofs with complex geometry or near tall obstacles. Additionally, multi-busbar (MBB) technology effectively shortens the electron flow path, which not only increases efficiency but also minimizes the risk of micro-cracks in the silicon structure. This product stands out from the competition with its low temperature coefficient, which ensures that the modules maintain high efficiency even during extreme summer heat. This solution is dedicated to investors seeking high mechanical durability and financial stability for their project. The use of PERC technology supports better absorption of diffused light, allowing the system to generate real profits from early morning until dusk, providing a fast return on investment in both the residential sector and demanding commercial installations.
