Very interesting concept from the Netherlands - they say they can get a SCOP of 4.5 with 2.7m2 of panels per KW needed

Hi Batalto,

Shortly after I had the solar PV system installed many years ago, I was looking at ways in which to optimise the output, and one of the things that I thought about was running water through copper pipes fixed to the back of the panels to cool them, and hence improve their efficiency. I did not go ahead with doing so because of the difficulty of retrofitting pipework on the panels, and also the fact that to maintain eligibility for FIT payments you cannot make modifications to your system without prior approval.

I am very pleased to see that someone else came up with the idea and actually produced a commercially available system. A system like this would certainly be useful for properties with limited space for mounting panels, either solar PV or solar thermal. Combined with the heat pump is even better, though I would be interested to see details of how the system works in practice. I assume that the PVT panels act as the Evaporator, and because the area of the panels would be much larger than an evaporator in a normal monobloc heat pump, there is no requirement for the large fan.

Do you have any details of the cost of the panels etc.
