Overview
The HANERSUN 645W HN21N-60HT645W Bifacial Solar Panel is a photovoltaic module from HANERSUN rated at 645 Wp. Its module efficiency is 22.8%. Under standard test conditions (STC) it delivers an open-circuit voltage of 43.8 V and a short-circuit current of 18.39 A — the two values used to check string sizing against the inverter limits. The module measures 2,172 × 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.
