    Is it possible to have solar panels on a house & have no water tank to heat the water. Could you use an electric shower & what could be used for taps at the sink? I've seen there are solar panels that can generate energy even on cloudy days but are these available in Ireland?

    There are three principle technologies;

    Photovoltaic: Produce electricity, and increasingly used on new houses to meet part L. Will become more common when you get paid for surplus electricity which is exported

    Solar: Can be tubes or flatplate - heat water and need a cylinder

    Thermodynamic: Effectively a heat pump that heats water using a small collector panel on the roof. Requires a cylinder..

    Yeah was thinking about the Photovoltaic is it true that you can have a battery installed in the house that keeps charging with the surplus energy?

    You could look at a phase change battery to store the PV energy and use that to generate hot water on demand when you need it - just watch out for placement, desired temperatures and dead legs. Avoids the need for a hot water tank and can be quite compact. I'm thinking of using one with a particular electric water heater as a backup - will PM you details....
