Overview
The Talesun 550W Solar Panel is a photovoltaic module from Talesun rated at 550 Wp. Its module efficiency is 21.1%. Under standard test conditions (STC) it delivers an open-circuit voltage of 49.8 V and a short-circuit current of 13.99 A — the two values used to check string sizing against the inverter limits. The module measures 2,300 × 1,135 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.
