Abstract
Owing to the effect of temperature on the maximum power point of photovoltaic
modules, the anticipated benefits of maximum power point tracking charge
controller are also greatly affected under high-temperature environments. This
paper presents experimental study results based on the investigations of the
effect of high cell temperatues on the performance of maximum power point
tracking charge controllers. The study was carried out over three months at
Kenyatta University in Nairobi, Kenya under moderate and high temperature
conditions. The experiments are carried out using two market-ready maximum
power point tracking charge controllers and a normal pulse-width modulation
charge controller as the reference. The study establishes that below 50 °C, the
maximum power point tracking charge controller exhibits significant
advantages over its counterpart with about 24% - 29%, additional energy gain.
However, at high cell temperatures, the maximum power point tracking charge
controller loses its added advantage over the pulse-width modulation charge
controller and its performance benefits drop from an average of 28% to 0.2%.
This demonstrates that an ordinary pulse-width modulation charge controller
would achieve the same yields under high-temperature conditions and at an
even lower premium.
