I agree with previous comments, I cant see January or february being very busy, people have other things on their mind, weather is usually bad, and anyone who knows the ins and outs and was looking at solar has probably had it installed before the deadline where possible, so there would always have been a natural lag before installs got back to a consistent level.
Back on the tools for me until things become clear, at least chopping out walls pays the bills and I have this to fall back on, even if I'd rather be project managing solar installs, its the EPC thats the decider without doubt.
