Not really testing, but the suppler recommends testing them before sticking them down. Kind of makes sense. I have a bad habit of buying things in advance and then forgetting I have them. Can be a nice surprize. I have wondered why I've purchased a second one, or it does not work. The warranty having expired 2 years ago. So out with the panels yesterday as it wasn't too windy. They are very odd in appearance though appear to be well made. I did not leave them on the roof waiting for low light conditions as I thought that would be tempting fate. Claimed to be rated at 120 watts per panel I managed to extract 100 watts per panel in my crude testing. I should just about be able to fit four of these on "Betty's" roof. The nature of the roof is partly why these were purchased. As with most coaches/busses I've play with the roof is not much more than a glass fibre bag over a steel frame. Generally they rely on not too many attachments to avoid leaking. The flexible panels should conform and move with the roof. So far I'm happy that they work.
