Bifacial output potential
Rear-side irradiance can lift total power beyond the front-side STC rating. TCL specifies approximately 770W–798W with 10% bifacial gain across the 700W–725W range, depending on mounting height, tilt, surface reflectivity and installation conditions.
Warranty
TCL Solar specifies 15-year product coverage and 30-year power coverage for this T Class range, with a minimum warranted output of 99% in year one and maximum annual degradation of 0.40%, subject to manufacturer warranty terms.
Important installation note
At 2384 × 1303mm and 38.2kg, this is a large-format high-voltage module intended primarily for commercial, industrial and power-plant style installations. Confirm structural loading, mounting system compatibility, inverter/MPPT voltage and current limits, string design, cable sizing and all applicable Australian electrical requirements before installation. It is not a nominal 12V battery panel.
