Solar panel - Sikaflex?

[LemonParty]

I've got a semi-flexible solar panel sat waiting to go on top of my campervan, and am going to stick it down with Sikaflex.

However, there are so many types of Sikaflex to choose from - which one should I use??

I used a full tube of Sikaflex 291i to stick down a 160W semi-flexible panel. Get two.
Be aware it grips immediately. I underestimated this and my panel's on the huh.

CT1, some of the better solar panel suppliers include it in their fitting kits, we use it at work & it's fantastic.

Assuming it's now profile, clean, and with a large bonding area, most should be be fine?

bit late to the party but hope this helps: fitted a Thule bike rack and solar panel to my Ducato recently and used this stuff (specifically listed in the Thule fitting instructions) -

Sikaflex EBT from Screwfix, hoping it works as I have just fitted a 120W rigid panel to mine today and used the EBT on the roof cable ingress box.

I used 3m VHB tape on mine to secure and sikaflex around the edges to stop the water getting onto the tape. Mine are raised and sit on 4 corner pieces and one in the centre on each side.
The 3m VHB tape is amazing and not that expensive but as yours is flat you should be OK with sikaflex.

I've managed to get hold of some Sikaflex EBT+ from Amazon so hope to get this done in the next couple of weeks, as soon as I've cleared enough of the other DIY jobs the missus keep giving me!

I've used Sikaflex 221 as it remains flexible and seems to be very similar to EBT. Not sure why they would make 2 sealants appearing almost identical. Been sealing all the trim (white) and need to do the windscreen and windows next (black). I had a couple of leaks and have been resolving them to halt any future huge problems and cost. There was lots of clear silicon (bodge and now removed) around and the black on the windows is just old (25 years) and I can see cracks and potential issues going forward. Once done it should see me out.
