I have recently bought some CIGS 75 watt panels for my Bay. They are these ones: https://midsummerenergy.co.uk/buy/flexible-solar-panels/miasole-75W-CIGS-flexible-solar-panel I spoke to midsummer about a potential group buy and they are willing to offer a decent % discount for a minimum buy of 10 panels. Postage wil be next day and £10, but if all who buy are going to Techenders I will deliver them direct then only one postage cost will be needed. Sent from my Pixel 4 using Tapatalk
Oh, and additional panels can always be added in the future. It is advised to fit panels from the same source to keep the system balanced so its worth planning ahead
Just for clarity, I assume these are not suitable for a roof such as mine which has three ridges running its length, and therefore the panel is not completely supported? My current panels are aluminium reinforced, but I assume these are not as it is unnecessary if they require complete support? They look great panels but probably not for a roof such as mine ( mine are fine btw, no complaints …. But thought it worth asking the question)
The panels can be fitted over contours but nothing with too sharp an angle. I have a westy roof with horizontal ribs, I was going to just go straight over these but have been advised to fill the gaps with something so it's all one flat surface. I will probably fibreglass it.

Or fix something to the roof which provides that support but is in itself flexible. I’m thinking the foam stuff they use for signs for example Very light weight and partially flexible.
You can buy 3mm thick pvc in 8x4 sheets. I think you'd have to be careful it wasn't exposed directly to UV perhaps. Dunno. Just recall pvc isn't long term stable on sun exposure but should be ok under the panel?
I’ve been using this material extensively: https://www.cutplasticsheeting.co.u...by_material/dibond-aluminium-composite-sheet/ Considering it for panel attachment to a Devon Poptop. Sent from my iPhone using Tapatalk
Nope, aluminium will heat the panels up and cause hotspots where my ridges are. These cogs do not need extra backing of any sort, I just need to full my small gaps so it's a smooth run. Having said that, putting them on the metal roof of a building or narrow boat is OK Sent from my Pixel 4 using Tapatalk
interesting to know @bernjb56 please could you clean up this thread to just people that are interested in buying the panels, and move the other stuff to a general solar panel thread? not meaning that to be rude to anyone else as i do find it intersting stuff but it will be easier to keep this on topic to the group buy only.
@pkrboo, would you be able to measure the height profile of the panel plus connector wires of a panel please. My garage door is only a few cm above my Westy roof and so in this case, size does matter! I've had a few really good conversation whist here at Keith's filed and having just seen Neil's set up (@theBusmonkey) it occured to me that the cables coming out of the panels looked quite high. Thanks for setting this group up.
I would say they are approximately 10mm high and the cables come straight out the back rather than upwards. Very low profile Sent from my Pixel 4 using Tapatalk
