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
