xElite Solar 625W N-Type Bifacial Dual Glass Solar Panel 23.3% Efficiency
PRE ORDER NOW - DELIVERY END OF JUNE 2026
The Elite Solar ET-N778TBH630-650GL is a high-output N-Type bifacial solar panel designed for commercial rooftops, ground-mounted arrays, agricultural buildings, and larger solar power systems where maximum generation and long-term reliability matter. With a power output range of 630W to 650W and module efficiency of up to 23.3%, this premium solar panel helps installers and system designers achieve more power from fewer modules.
Built with advanced N-Type cell technology and durable dual-glass construction, this Elite Solar panel is engineered for dependable performance in demanding environments. In addition, the bifacial design allows the rear side of the module to capture reflected sunlight, helping improve total energy yield in the right installation conditions.
High-efficiency bifacial solar technology
This Elite Solar panel combines modern N-Type solar cell technology with bifacial energy generation, giving you a strong solution for high-performance solar systems. Because the module can generate from both sides, it is especially well suited for ground-mounted projects, light-coloured surfaces, and flat roof systems where reflected light can increase overall production.
Built for long-term reliability
The dual-glass design improves durability and supports a long service life. Elite Solar backs this module with a 12-year guarantee on product material and workmanship, together with a 30-year linear power output warranty. This makes it a strong choice for installers and buyers looking for long-term confidence and low lifetime degradation.
