Its bifacial design can capture rear-side irradiance where installation conditions allow, while its 2.0 mm double-glass structure and high static-load ratings support robust, professionally specified solar arrays.\u003c\/p\u003e\n\n\u003ch3\u003eImportant Notes\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eElectrical ratings are measured at standard test conditions: 1,000 W\/m² irradiance, 25°C cell temperature and AM1.5G spectrum. Actual output varies with irradiance, temperature, orientation, shading, rear-side irradiance and system design.\u003c\/li\u003e\n  \u003cli\u003eBifacial gain is site-dependent. The datasheet provides electrical characteristics at a 10% rear\/front solar irradiance ratio, but actual rear-side production must be modelled for the installation.\u003c\/li\u003e\n  \u003cli\u003eConfirm string voltage, inverter input limits, mounting compatibility, connector compatibility and local installation requirements before purchase or installation.\u003c\/li\u003e\n  \u003cli\u003eFor Nextracker installations, the datasheet advises referring to the compatibility approval letter between JA Solar and Nextracker for maximum static-load guidance.\u003c\/li\u003e\n  \u003cli\u003eThe datasheet lists QC 4.10-351 or MC4-EVO2A connectors.
