Bumpy installation. As with any long term investment, though, should revisit the review in 2, 5, 10 yrs.
Positives: TE install industry leading SolarEdge gear; there is usually someone available to talk to at the helpline. I'd love to be able to say all went well, alas it did not. The contract did not include a timetable of work. Relying on the sales message in this respect left too much room to interpretation and misunderstanding, which did happen. The scaffolders were extremely unreliable. Elevation/removal dates moved many times, causing delays, wasted effort and frustration. On their last visit, the scaffolders fly-tipped a stray tree branch against a neighbour’s garden wall. After the scaffolding had gone, it became clear that four gutter support brackets suffered damage. Communication between office and those working on customer premises: room for improvement. E.g. the installers were unaware that the job included the bird guard until I pointed this out. Next, I was assured twice by office staff that a certain job had been agreed, only to hear the electrician deny any knowledge of this, also twice. At one point, TE reissued the contract; this was triggered by a minor change to the panel spec (415 to 420 Wp). I noticed that, unexpectedly, the update was not limited to the 'panels' entry but the general contract wording changed, too. So I had to reread 30+ pages and rediscuss my findings; could have done without this. I could go on. All that said, I'm happy with the system. If long term reliability and aftercare is good I may come to view TE more favourably in future.
