For two years now, the entrepreneur has no longer heated his home with gas, using instead a brine-water heat pump. That would not be a surprise, as such a system is a standard solution, with the brine being heated up with geothermal energy via a borehole and the heat pump powered with solar energy from the roof. Siegerink, however, did not use a hole in the ground. He developed an attachment that he strapped onto the back of the photovoltaic modules as a heat source for the brine-water cycle. He now produces and sells this solution with his company UseAllEnergy.

 

With this attachment, a heat exchanger, he transforms standard photovoltaic modules into photovoltaic solar thermal (PVT) modules. Such hybrid panels have been around for a long time. However, they couldn’t prevail on a larger scale. One reason for this is that the conversion of a standard PV module would put at risk the manufacturer's guarantee. Another reason is that the water temperatures are not close to the temperatures that pure solar thermal collectors can offer and heat yield is limited to very sunny days. Siegerink was able to solve both problems.

Not a new idea, there must be a reason why it has not caught on.

Maybe frosting of modules, snow staying put, harder to install, expensive.

I suspect it is easier to just fit separate PV and an ASHP.

So by strapping the collector to the back of the PV panels, he has turned his water to water heat pump, into an air to water heat pump.
