on the plus side, I think that in the right circumstances roof top commercial PV will still be reasonably financially viable if we can keep costs down.
UK PV costs though are so reliant on GBP / EUR exchange rates that any signficant rise could further decimate the industry, as there'll be no margins to absorb it.
Surely you're going to need volume to get the cost down though Gavin? I'm not even looking past December now - most of ours struggle to get a D rating with pv.
