Photo voltaic thermal panels

    So, we are building a house and wondering if we should include solar or not. Has anyone any experience with PVT panels? (PV panels cooled by cold water which is pumped into the heating system?

    Sounds like a gimmic and a likely point of failure. PV doesn't get that hot in Ireland, the cells absorb most of the energy while the glass reflects what's left.
    They'd be great for the Sahara, Dubai etc...the colder PV is, the better it works.
    We do pretty well with wind chill. Unless you go buy bleedin' silly sticky thin flexible non UV stable panels and heat sink them to a van roof...popular idea...:rolleyes: ...dead in 4 years
