Up to now, Ireland had one of the worst feed in tariff regimes in the EU. Electric Ireland would buy back surplus electricity from solar photovoltaic or other microgenerators for 9c per kwhr. That is to be scrapped after 31st December.
The financial case for those of us trying to sell photovoltaic panels to domestic users falls apart if you cannot get paid for electricity exported to the grid.
Most countries have various carrots to encourage solar PV on the grid. We only have a stick. New houses must produce renewable energy to meet Part L of the building code, and solar PV is by far the cheapest way to do it, but it would be nice to get something for the surplus power.
