Had a solar installation in the past 12 months - the information beforehand (we bought via a local council scheme) was really good, the two chaps who installed the equipment and initialised the system were excellent, worked very hard and were really pleasant. The system itself has been good, wish we had opted for a battery but were talked out of it. The only thing that let it down was the actual booking process. We had scaffolders turn up out of the blue when we had already booked in dates and times, so that we would have someone at home to meet them, and then the installation happened on a completely different day than we had booked. The documentation for the installation, and that needed to get the whole system accepted by the electricity company was delayed massively, some due to COVID, but also due to things not being followed up. We are there now though, 12 months down the line. Shame because the rest of the process has been really good and worth doing.
