Photovoltaic Efficiency: The Temperature Effect

www.teachengineering.org

The temperature dependence of a material is described with a temperature coefficient. For polycrystalline PV panels, if the temperature decreases by one degree Celsius, the voltage increases by 0.12 V so the temperature coefficient is 0.12 V/C. The general equation for estimating the voltage of a given material at a given temperature is: where: V

Try to make sure that the level of pain does not get ahead of pain-relieving medicines. Tell the doctor or nurse if the pain is not controlled.
