[QUOTE="Tony Norton, post: 542718, member: 36439"] Hi All, it was about 15 years ago that I fitted a single solar panel to a motorhome we owned. After research I had found that "triple junction" panels were, at the time, the most efficient one could get. Reason was they had 3 layers of sensors that reacted to different wavelengths and levels of light. The panel on our 'van was pumping power into our battery when the light was at a very low level e.g. dusk and dawn. It didn't require bright unclouded sunlight, just light in whatever form was available. I recently had contact from several solar panel suppliers wanting to quote me for supplying and fitting panels. When I asked the question "Are they triple, or multi-junction?" the answer was, without exception, "Leave that with me, I'll get back to you". Did they? Did they b*****y! They either didn't know what I was talking about, or they didn't want to deal with someone who was not prepared to accept the cheapest rubbish they could get their hands on. Try it next time you're talking to an alleged[I] expert[/I] from a fully qualified and experienced firm. So called! Tony N [/QUOTE]
