    If you are doing it to save money, then the payback on a PV system at 9c per KwHr is poor enough. You can reckon on a hardware cost of slightly under €1 per watt so at 9c you would get €1260 back per year on a €16k outlay.

    Equates to roughly 7.9% return on investment tax free. Not too bad imo.

    Yes - though that cost of €1 per watt is for an industrial system. PV does stack for industry that has a daytime baseload so that they are using all of the electricity produced. If you are looking at a domestic roof installation, it would cost a bit more, and most households are not using electricity during the day, so more of their production is exported at the 9c tariff.

    I think it is worth doing, and have PVs myself. I like having clean electricity from an ethical point of view.

    That and when I appreciate what it takes to generate my own power and how frivolous having constant running electrical loads are I have a much lower impact. A high ESB bill has nowhere near the same implications as a battery bank at 50% DOD.
