Recommended adhesive for solar mounts
Sika mounting adhesive is one of the strongest products available. It has a great "working time" for acurate installations.

Super sticky mastic glue
Super sticky mastic glue that I used for installing my campervav solar panel mounting bracket (QWORK drill free 7 piece set). Product is very sticky and really thick / glutinous and can be a bit hard to squeeze out of the mastic gun. Or rather my grip was getting tired towards the end. Left the solar panel in place with some wieght on it over night and it was solid fixing.

El mejor
1 año después y tras haber estado en el ártico no ha sufrido nada, ninguna grieta ni dureza, el sika anterior no aguantó en la misma autocaravana

Seems solid and doing the job.
I used this to bond a DIY Van fan adapter to the roof of my 2004 Sprinter. And to bond a wood frame I made for the underside of the opening. I would definitely use this again for anything similar.
