Best for My Roof
02 June 2023  | 

I had intended to to buy 18 cheaper panels but these were available and the service from County Electrical was responsive. I've yet to get a reply from a Machester based supplier. Although the price per watt was dearer, with the higher wattage I needed two panels less, saving on mounting hardware and install time. The additional space around the edge of the panels will make installing the bird netting easier. I've no previous experience of PV panels for compaarison but they appear well made. They are of a common size but larger than I visualised. I'd planned to carry the up a step ladder but have revised this plan and ordered a plasterboard hoist.

Two very nice chaps carried each panel individually between them to the top of my drive and laid them on a sheet of cardboard. Excellent service, goods delivered with care and in perfect condition.

Thanks very much, best regards,

Ian Pinkard
