Abstract In this work an experimental work was conducted to improve the performance of photovoltaic panels (PV) by cooling them using phase change materials (PCM).
You can see in the P-V curve that as the solar radiation decreases from 1000W/m2 to 200W/m2, the power drops proportionally – from 300W to 60W. The Voltage output range remains nearly constant, however with the Maximum Power Point (MPP) voltage at 33V, and the maximum open circuit voltage only dropping from 43V to 38V.
Here’s what we learned: Solar panels, unless heavily shaded have a remarkably high and consistent voltage output even as the intensity of the sun changes. It is predominantly the current output that decreases as light intensity falls. Panel temperature will affect voltage – as has been discussed in another blog.
It’s important to make and break these connections only when the panel is under no load – this means either covering the panel to exclude light, or working very early or very late in the day.
Due to the nature of the semi-conductive silicon in PV cells, the effect of a blocking shade on the solar panel is so severe that if a single cell (of which there can be between 36 and 144 in each panel) is completely shaded, it will completely restrict the flow of electricity through it.
Solar panels have built-in bypass diodes to skip a troublesome cell group (usually several horizontal columns of cells) allowing the energy from the other unshaded cells to flow once more.
