    That's true - a 3Mw turbine on a mountain is hugely more cost effective than a 10kw turbine on a farm. But the same economies of scale don't apply to solar PV. In fact, it is cheaper per Kw to put solar PV on a factory roof than it is to build the solar parks now being proposed by investors who are already signing up farmers and making planning applications in anticipation that policy is going to go their way.

    When you take into account the substation and transmission lines the PV farm makes more sense, as well as the fact that can enter the SEM.

    Usually, a factory would install a system smaller than its peak consumption, so the grid infrastructure is already in place. So PV farms are less cost effective because they usually require a grid feed and transformer.

    The fact that they can enter the SEM favors the current model where ESB likes the grid to be used for buying and selling electricity, but it isn't necessarily the best model for consumers or industry.

    Microgenerated does not need either of these to be built. It reduces the load on transmission lines.

    Might be interesting to some but I just got the offer from our network operator here in Germany for our new house connection (we're building). It's a bog standard connection (the cheapest one lol). It's rated at 100A, three phase and interestingly in the letter of offer they state it can be used to feed up to 30kW into the network. We plan a 9kWp installation, so this is more than enough for us, even if we add more panels on the roof of our planned garage later.
