The pvc is not as good as copper in heat conductivity, so the heat transfer will be slower and the amount of energy absorbed will not be as much as the copper. and since the pvc is plastic, it will sag and it doesnt have a long life span. the solar panels will then become less effective and you will need to replace the pvc pipes in the solar panels more often.
