Very responsive company to detail with and helpful. Flexible in design stage to come to mutual solution as I had a ground mounted system fitted and doing the prep work myself. Project got delayed slightly due to communication error (on both sides) and was in danger of grant application expiring....PV pulled out all the stops to get it back on track at all levels and a genuine 'listen to the client' attitude. Installation team on the day were professional/polite/punctual.....could not fault. Highly recommended
