Overview
The GCL 680W Solar Panel is a photovoltaic module from GCL rated at 680 Wp. Its module efficiency is 21.9%. Under standard test conditions (STC) it delivers an open-circuit voltage of 46.98 V and a short-circuit current of 18.24 A — the two values used to check string sizing against the inverter limits. The module measures 2,384 × 1,303 mm.
When designing strings, correct the Voc for the lowest expected site temperature: on cold mornings the string voltage rises several percent above the STC value.
