I don't consider the job finished until the scaffolding has been removed, and things are all in order. having read the manual left to me I see I need a certificate of warranty for the solar panels and the batteries I have neither. I need some security to know I am paying the correct people . over the phone could be anyone asking for the money...no bill. Also they asked for more than I had I agreed when I signed the permission form. That's not right to be told one price and then asked for more.. Alson I was told that there would be a metre installed in the kitchen so that I could easily see the generation, this is now by smart phone. Yes I have one but don't really use it except for keeping in touch with one of my sons, Your men installed the app for me but if anything happens to delete the app I have noidea what to do to reinstall the app. Now having checked the loft I see 3 nails that have completely missed the roof timber, could this result in instable panels. I also didn't expect to loose my TV signal for the duration of the scaffolding. Information has been minimal and emails have not been answered. There has been a lot of waiting in for work men to arrive . Phone calls saying when the men are comeing should be standard .I am usually a very prompt payer of my bills and I will pay the amount I agreed to as soon as the job is finished with all aspect taken care of. Warranty certificates are a must or the warranty to useless. There are too many short comeings to give a higher rating although the panel fitters and the electician worked well and were helpful, it was them who told me why my TV had no signal, and they also made sure my gates were locked correctly.
