6 FAQs about [Photovoltaic equipment battery junction temperature]

What is the junction temperature of a PV module?

For example, for the combination of (irradiation, ambient temperature) = (1000 W/m 2, 25 °C), the junction temperature Tj shift from 54.66 °C to 62.54 °C as the output current of the tested PV module changes from 0.5 A to 7.0 A.
