Product Overview
The Trina Vertex S+ TSM‑420NE09RC.05 pairs sleek aesthetics with advanced N‑type TOPCon and PERC cell technology in a black‑on‑black bifacial format. The panel delivers 420 W of reliable output while maintaining a relatively small footprint—perfect for space-conscious residential and commercial installations. Its dual‑glass build not only enables backside light capture, enhancing energy generation by up to ~30 %, but also improves durability against environmental stressors such as salt spray, humidity, and temperature swings
Featuring third‑cut PERC cells and high‑density interconnects (HDI), Vertex S+ panels minimize resistive losses and improve shading tolerance. The result: up to ~21 % module efficiency in real‑world conditions, with excellent thermal behavior thanks to a low temperature coefficient that limits power loss in hot weather
Durability is built in: the panel is certified to endure coastal conditions, sand, dust, ammonia exposure, and carries strong fire and quality ratings. With engineering to withstand 6000 Pa and 4000 Pa load, it’s engineered for both heavy snow and high wind regions
Installation is simplified with a modest weight (~47 lbs) and standard MC4‑EVO2 cable and connector configuration. At 1500 V system voltage compatibility, it’s future‑proof for large installations and high voltage string designs
Why Choose Vertex S+ TSM‑420NE09RC.05?
-
Maximize rooftop power: smaller size lets you fit more watts per square meter.
-
Durable, long-lasting design: dual glass and strict testing minimize wear and tear.
-
Peace of mind warranties: 25‑year product and power guarantees keep energy yield predictable.
-
Outstanding in heat: low temperature coefficient ensures stable output even during hot days.
-
Industry‑standard integration: works with mainstream inverters and racking systems.
