About the Resun 460W Monofacial Solar Panels RS8R-M TopconThe Resun 460W Monofacial Solar Panels RS8R-M Topcon is part of Resun Solar Energy Co., Ltd.’s advanced TOPCon (Tunnel Oxide Passivated Contact) series — a next-generation panel that combines high efficiency with durability and long-term reliability. These modules are engineered to deliver reliable solar energy conversion across a wide range of environments, with optimised performance under real-world conditions.Detailed FeaturesHigh Power Output — 460 WWith a nominal power rating of 460 W, the RS8I-M panel delivers substantial energy output per module, helping reduce overall system cost (fewer panels required for a given system size). Advanced TOPCon Cell TechnologyTOPCon technology offers improved cell passivation, which reduces electrical losses and increases efficiency over conventional PERC modules. This yields better conversion rates and enhanced performance even in low-light conditions. Multi-busbar and half-cell designs further reduce internal resistive losses and improve reliability. High Efficiency & Low DegradationThese modules are designed to provide high conversion efficiency and stable energy production over time. Backed by a 30-year linear power output warranty and generally low annual degradation (for example, ~0.5 % per year typical across similar Resun models). Robust Weather & Mechanical DurabilityBuilt with tempered glass and a durable aluminium frame, the panel can withstand harsh environmental conditions including wind and snow loads. Rated for up to 1500 V system voltage, suitable for larger commercial or utility-scale array systems. Junction box with IP68 protection for reliable operation in variable weather conditions. Certified Quality & ReliabilityResun panels undergo stringent testing and are certified to global industry standards such as TUV, IEC, CE, and are insured through the CHUBB Insurance Group.Technical SpecificationsModel: RS8R-M Topcon Rated Power (Pmax): 460W Open Circuit Voltage (Voc): 53.30V Short Circuit Current (Isc): 10.90A Maximum Power Voltage (Vmp): 45.07V Maximum Power Current (Imp): 10.21 Module Efficiency: 23.02% Solar Cells: Mono-crystalline TOPCON 210*182mm, 16/18 Bus bars Cell Configuration: 144 Cells (6*22) Front Cover: 3.2mm Tempered Glass J-Box: IP68, 3 Diodes Cable: 4mm²(IEC)/12AWG(UL), 300mm 300mm, or customized length Connectors: MC4 or MC4 Compatible Nominal Operating Cell Temperature(NOCT): 45°C±2°C Temperature Coefficient of Voc: -0.25%/°C Temperature Coefficient of lsc: 0.045%/°C Temperature Coefficient of Pmax: -0.30%/°C Operational Temperature: -40~ 85°C Maximum System VoltageMax: 1500V(IEC)/1500V(UL) Series Fuse Rating: 20A Limiting Reverse Current: 20A Certification: IEC 61215/61730/61701/62716ApplicationsResidential Solar Systems — Power homes with a high-efficiency panel that maximises rooftop space.
