Description
The JA Solar 605 W panel is one of the modern high‑performance photovoltaic modules designed for maximum output, durability, and long‑term efficiency. Key features and typical specifications:
-
High Power Output: The panel is rated for 605 W (Pmax) under standard test conditions (STC), making it a strong choice when you want high capacity per panel and want to minimize number of modules.
-
Cell & Module Technology: Uses N‑type monocrystalline cells with advanced technology (often Half‑Cell + Multi‑Busbar / SMBB) and a bifacial, double‑glass (glass–glass) construction. This design enhances light capture (from both front and rear sides), improves durability and reduces degradation — a feature particularly useful for high-efficiency, long-term installations.
-
Efficiency & Performance: Module efficiency is typically around 22.5–22.8% depending on exact variant.
-
Physical & Mechanical Characteristics
-
Cells: 144 (half‑cell layout, usually 6 × 24)
-
Dimensions: ~ 2465 mm × 1134 mm × 35 mm (some variants might have slightly different dimensions, e.g. 2382 × 1134 × 30 mm depending on model series)
-
Weight: ~ 33–34.6 kg depending on variant and glass thickness.
-
Junction Box & Connectors: IP68‑rated junction box, typically with 3 bypass diodes; standard connectors like QC4.10-35 / MC4‑EVO2 are used.
-
-
Operational Conditions & Durability: The module is built to handle a wide operating temperature range (commonly –40 °C to +85 °C), making it suitable for varied climates.Its glass–glass bifacial construction and robust frame also confer good resistance to environmental stress (wind, dust, moisture), enhancing long-term reliability and lifespan.
-
ld Conditions: Bifacial design can add extra energy yield when rear‑side irradiance or reflective ground is available — often providing a “bifacial gain” compared to monofacial panels if installation and site conditions are favorable.
-
Warranty & Lifespan: The panel typically comes with a standard product warranty (often ~12 years) and a long-term power output warranty (e.g. 25–30 years), promising stable performance and output over decades.
