This study examined two years of temperature, humidity, and irradiance data collected at intervals of fiv minutes for the city of Jos, Nigeria to determine the relationship between temperatures Photovoltaic system voltage, and power output. Descriptive statistical tools were used to investigate the relationship between temperature, power output, and voltage. There is a wider range of responses to temperature change in the output power. The findings showed that the power output values range from 227.82 kWh to 950.10 kWh, and Voltage values range from 14.41 V to 16.12 V. Additionally, the average monthly temperature ranged from 20.42 ? to 25.76 ?. The result shows a positive correlation between temperature below standard test condition (STC = 25 oC), and high output power, while a high temperature above STC negatively affects the output power. Notably, Jos has a higher power output and voltage while maintaining the lowest average temperature compared to other locations within the region. The study concludes that power output and voltage are strongly and inversely related to temperature, refuting the notion that operating solar panels above STC would improve performance.
