Hi all, Last year I took the van to a Conversion company where I had the interior carpet lined and a pop top roof fitted along with a 150w semi flex solar panel on the roof. About a month ago the solar panel failed. It was still under warranty so I went back to the installer who was willing to replace it under warranty with no quibble. Before we got into that, I asked the question - How many of these have you experienced have failed, the answer was 10, which I though was a lot. As I didn't want to repeat the same mistake again, I asked about alternatives. I eventually opted to upgrade(at an extra cost) to a 250w semi flexible panel after I had asked the same question about how many they had experienced fails on this type, the answer was 'None'. The first panel had a 2 year warranty where as the replacement has a 5 year warranty. I hope this thread helps any first timers in some way when choosing which solar panel to opt for.
