Sensorless approach for PV panel temperature monitoring

Researchers in United Arab Emirates have developed a novel model that relies on either the open-circuit voltage or the maximum power point voltage to estimate PV module operating temperature without using sensors.Researchers at the Dubai Electricity and Water Authority (DEWA) R&D Center have developed a novel sensorless self-thermometry approach to estimate PV module operating temperature. Dubbed the Shift-Factor method, the new method works by analyzing changes in either the open-circuit voltage (Voc) or maximum power point voltage (Vmp). "By correlating these electrical responses with irradiance ...
