JPEE, 2020. The performance of solar PV modules is significantly affected by temperature. This paper focuses on the determination of the effect of temperature on a commercial mono-crystalline silicon PV module whose temperature coefficients were not provided by the manufacturer for installation in Kumasi, Ghana, Sub-Saharan Africa (SSA) ambient.
In [2], the authors indicate that increasing the PV cell temperature by 10 °C results in a 4% energy loss. For this reason, accurate knowledge of the photovoltaic cell temperature is essential for the correct prediction of the energy produced [5]. In the literature, different models have been suggested for predicting PV cell temperature.
