> covering some less-useful land in ground mount photovoltaics.
Doesn't even need to be less-useful land (especially in western Europe, ground is becoming a scarce resource), put PV on flat rooves or add them over open car parks. Also helps alleviate pressure on the overstressed energy grid by generating and using power more locally.
But, local power is (overall) a lot more costly than major centralized power generation projects, like a wind farm or what have you.
Ironically, renewables tend to put a different kind of stress on the grid: frequency. In Ireland the grid can't handle windy days, so there are ROCOF issues and "dispatch down" events which means clean energy is lost.
I'd expect storage/batteries can help smooth this out by providing shiftable demand/production (with the right local control software running on/near the inverter)

Not sure if this is prominent in the Irish market or not
