Technical FAQs 4

What is the temperature coefficient of a solar cell?

The temperature coefficient of a solar cell is the amount by which its output voltage, current, or power changes due to a physical change in the ambient temperature conditions surrounding it, and before the array has begun to warm up.

What is a photovoltaic cell temperature?

The photovoltaic (PV) cell temperature is the temperature of the surface of the PV array. During the night, it is the same as the ambient temperature, but in full sun, the cell temperature can exceed the ambient temperature by 30°C or more.

How to determine the power output of a solar cell or module?

So, to determine the power output of a cell or a module, it is essential to determine the operating temperature (expected) of the cell or module. The Nominal Operating Cell Temperature (NOCT) is the value of temperature reached by open-circuited solar cells in a module under certain conditions.

How does the arrangement of solar cells affect a PV module?

The way solar cells are arranged to form a PV module, has a side-effect which physically affects the PV module. The arrangement of PV cells into a module changes the flow of heat into and out of the module. A changed flow of heat means that the temperature at which the module operates increases.
