Trina Solar Vertex S+ TSM-435 NEG9RC.27 435W N-Type TOPCon Black Frame Solar Panel
The Trina Solar Vertex S+ TSM-435 NEG9RC.27 Black Frame solar panel is a high-performance photovoltaic module designed for modern residential and commercial rooftop solar installations. Built using advanced N-type TOPCon cell technology and a bifacial dual-glass design, this premium solar panel delivers outstanding efficiency, durability, and long-term power generation. With a nominal power output of 435 W and module efficiency reaching up to 22.0%, the Vertex S+ series is engineered to maximize solar energy production while maintaining a compact and installer-friendly format.
Advanced N-Type TOPCon Cell Technology
The Vertex S+ module utilizes next-generation N-type TOPCon solar cells, which provide improved electrical performance and superior reliability compared with traditional photovoltaic technologies. N-type cells are less susceptible to light-induced degradation and offer improved resistance to environmental stress. As a result, solar systems built with this technology maintain higher power output and long-term stability throughout their operational lifetime.
The module also features high-density cell interconnect technology, which increases energy conversion efficiency while reducing internal electrical losses. This design contributes to higher power output per square meter and improved system performance.
Bifacial Dual-Glass Design for Increased Energy Yield
The Trina Vertex S+ module features a transparent dual-glass structure, allowing the rear side of the panel to capture reflected sunlight and convert it into additional electricity. With a bifaciality factor of approximately 80%, the module can significantly increase energy production compared with conventional single-sided photovoltaic panels.
The dual-glass construction also enhances mechanical strength and durability. Compared with traditional backsheet modules, the glass-glass design improves resistance to micro-cracks, moisture ingress, and environmental degradation, ensuring long-term reliability even in demanding climates.
Optimized for Residential and Commercial Rooftop Installations
The Vertex S+ series is specifically designed for residential and commercial rooftop solar systems, where installation efficiency and compatibility are critical. The module dimensions of 1762 × 1134 × 30 mm and a weight of approximately 21 kg provide an ideal balance between power density and ease of handling during installation.
The module is compatible with most standard solar mounting systems and mainstream solar inverters, allowing installers to integrate it easily into existing photovoltaic system designs. Its compact format makes it particularly suitable for rooftops with limited structural load capacity.
Strong Mechanical Performance and Environmental Resistance
The module is engineered to withstand challenging environmental conditions. It supports mechanical loads of up to 5400 Pa on the front side and 4000 Pa on the rear side, ensuring reliability in areas with heavy snow or strong wind. The panel also offers excellent resistance to salt mist, sand, ammonia, and other harsh environmental conditions, making it suitable for coastal or agricultural installations.
Long Warranty and Low Degradation
The Trina Vertex S+ solar panel is designed for long-term reliability and stable performance. It features only 1% degradation in the first year and an annual degradation rate of 0.4% thereafter, ensuring consistent power production throughout its operational lifetime.
The manufacturer provides a 15-year product warranty and a 30-year linear performance warranty, guaranteeing dependable energy generation for decades.
The Trina Solar Vertex S+ TSM-435 NEG9RC.27 Black Frame solar panel is a high-efficiency photovoltaic solution for professional solar installers, EPC contractors, and solar distributors seeking reliable modules with advanced technology, strong performance, and excellent long-term value.
