Bifacial 410 Watt Monocrystalline Solar Panel (with Z-brackets)

High Conversion Efficiency Mono-crystalline Silicon Our household-sized panel. Warrantied for 25 years. Cable and MC4 connectors are included on the back of each panel. (4) Z-bracket mounting hardware included! Bifacial increases efficiency by up to 10% High module conversion efficiency 21.0% Designed for Outdoor Use. IP68 junction box, high water proof level. Design Life 25 Years, power degradation as low as -0.45%. These High-Performance Cells are encapsulated in EVA (ethylene-vinyl-acetate) and then placed between high-transparency, low-iron tempered glass and a durable TPT (tedlar-polyester-tedlar) backing sheet. 108 cells - mono perc calf cut technology, better energy yield. The panels are framed using heavy-duty anodized aluminum frames providing exceptional panel rigidity.
