Investigation of the Effect of Temperature Coefficients on Mono-Crystalline Silicon PV Module Installed in Kumasi, Ghana

Abstract

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 order to determine the effect of temperature on the output characteristics of the module, the temperature coefficients of current, voltage and power were determined. First of all, the module was cooled to a temperature between 10˚C-15˚C in a cooling chamber, covered with cardboard paper before the outdoor electrical tests using Daystar I-V Curve tracer. The results show that as temperature increases, irradiance decreases significantly leading to a decrease in output power (P max). The open circuit voltage (V oc) also decreases, whilst short circuit current (I sc) increases slightly. The temperature coefficients were obtained from the slopes How to cite this paper: Takyi, G. and Nyarko, F.K.

Penerapan Algoritma Fuzzy Logic Pada Solar MPPT Controller

“…Panel surya memiliki karakteristik daya berdasarkan intensitas radiasi cahaya, dimana terdapat titik tegangan dimana modul PV menghasilkan daya maksimum yang disebut "maksimum power point" (MPP) (Subekti Yuliananda, Gede Sarya, et al, 2015) (Syamsul Bahri Widodo, Zainal Arif, et al, 2015. Diketahui pada penelitian lain yang telah dilakukan, pengaruh suhu akibat radiasi cahaya matahari , dan beban listrik yang besar turut mempengaruhi efisiensi panel surya (Gabriel Takyi, Frank Kwabena Nyarko, 2020). Panel surya umumnya menghasilkan daya maksimum pada tegangan 17.1V/25°C, dan 15V pada cuaca yang sangat panas, sedangkan diketahui pada kondisi yang sejuk tegangan panel surya dapat mencapai 18V (Sankar Selavkumar, Madhusmita Mohanty, et al, 2018).…”
