New Upgrade 480w Solar Shingle Module HJT Photovoltaic Cells Solar DIY System Kits

These cutting-edge 480W solar modules combine heterojunction (HJT) cell technology with shingled interconnection for maximum efficiency (22.3%). The panels feature ultra-thin silicon wafers sandwiched between intrinsic amorphous silicon layers, reducing recombination losses. The shingled cell arrangement eliminates front gridlines while increasing active surface area. The result is a panel with excellent temperature coefficient (-0.26%/?C) and superior low-light performance. The DIY kit includes two 240W panels, microinverters, and all necessary mounting hardware for rooftop installation. The panels feature sleek all-black design with 35mm frame depth and weigh just 22.5kg each. With PID-resistant construction and 0.25% annual degradation rate, these panels maintain performance longer than conventional designs. Includes 30-year linear power warranty (90% at 30 years) and 15-year product warranty. The integrated microinverters enable panel-level optimization and monitoring via smartphone app. Ideal for homeowners seeking professional-grade performance in a DIY-friendly package. The panels’ high voltage characteristics allow for systems with fewer strings while maintaining high efficiency. Certified to IEC 61215 and IEC 61730 standards with additional testing for hail impact (35mm) and wind load (2400Pa) resistance.
