LEFENG High-efficiency Grade A 144 Half-Cell Bifacial PV Module 525~550W Monocrystalline Silicone Photovoltaic Module 182mm Waterproof Solar Panel
Product Detail
— Product introduction:
• By using bifacial PERC cells and double glass technology, the total power generation of bifacial double glass module can increase up to 25%~30%.
• Based on the half-cell technology, the module produces higher power output and effectively reduces the system cost; The half-cell technology helps to effectively alleviate the hot spot risk, reducing shading loss and lowering internal resistance
• To maximize the customer value by more power yield generation and less carbon emission
• Materials: high-quality A-grade solar cells. Surface made of high transmittance tempered solar glass with weatherproof coating; corrosion-resistant aluminum frame for extended outdoor use with pre-drilled mounting holes; IP68 junction box with 30cm long 4mm² double insulated solar cable
• Application: On-grid or off-grid for ecological houses, cottages, caravans, motorhomes, boats etc. for all needs around a self-sufficient and mobile power supply.
• Warranty: 12 years PV module product warranty and 30 years linear warranty
