AB  - The impact and effect of photovoltaic panel temperature on the energy conversion efficiency of solar
energy to electricity was studied empirically. In the analysis, the photovoltaic panel is placed under
steady-state condition where the relative hvumidity and solar irradiance is assumed to be constant throughout
the experiment. The preset conditions are necessary to ensure that other environmental factors such as wind
velocity, ambient temperature and humidity have a negligible effect on the operating temperature of the
photovoltaic module. In a steady-state controlled environment, the experimental results show that the measured
voltage, current and its power decrease with time as the temperature of the photovoltaic panel increases.
Consequently, the efficiency of the photovoltaic module will also decrease progressively. Thus, to maintain
the efficiency of a photovoltaic panel, cooling technologies should be implemented to ensure the panel works
within the optimized temperature. Therefore, the need to invent feasible solutions to decrease the operating
temperature of the PV cells is vital.
