At an ambient temperature of 50°C the cell temperature is 78°C. 78°C – 25°C (STC) = 53°C x -0.07992V/°C = -4.23V. This would reduce the module Vmp to approximately 14V (18.3-4.23=14.07V), and Voc to 18V (remember Voc is at 0A, no current).

6 FAQs about [Solar cell to ambient temperature]

What is the temperature coefficient of a solar cell?

The actual value of the temperature coefficient, in particular, depends not only on the PV material but on T ref , as well. It is given by the ratio 1 ref oref TT (4) in which T o is the (high) temperature at , Garg and Agarwal . For crystalline silicon solar cells this temperature is 270 o C, Evans and Florschuetz .

Does the operating temperature affect the electrical performance of solar cells/modules?

In this paper, a brief discussion is presented regarding the operating temperature of one-sun commercial grade silicon- based solar cells/modules and its effect upon the electrical performance of photovoltaic installations. Generally, the performance ratio decreases with latitude because of temperature.
