Hi,

I'm after some advice, I've got space on my south facing roof for between 18-20 panels, but every installer I've been too is recommending that I limit the number of panels and install a 3.5Kw Inverter so that the DNO can be completed post installation, they all seem to have a reluctance to install a bigger system. Is this reluctance due to the timescales of getting a DNO, or is their a technical install reason for not wanting to go above this limit?

Thanks
 
I believe anything above 3.5kw around 16A on a single phase domestic property brings with it a whole host of extra rules and things to tick off, So yes the DNO would need to be involved, some are quick to respond (WPD) others can take 10 or more weeks to even reply and come out to take a look. Bear in mind the jump from say 3.5kw to say 7kw wouldn't just be double it could be say 2.5X more as the increase in kw brings with it higher rated switchgear etc

What's a DNO?
