Can you use adhesive on solar panels?

I strongly urge you to avoid using any adhesive for solar panels. Keep in mind that flexible solar panels don't last long. You will probably need to replace them every couple of years. That will be a challenge with them glued in place. For rigid panels, the best adhesive would be M6 bolts.

How much adhesive do I need for a solar panel bracket?

If you're using adhesive you want as much surface area connection between the bracket and the roof. A couple inches of bracket may not be enough. Using adhesive under Unistrut that matches the full length of the solar panels is much better. But I'm a lot more comfortable with actual fasteners.

How much adhesive do I need for a flexible panel?

What is the best adhesive for rigid panels?

For rigid panels, the best adhesive would be M6 bolts. These are rigid panels being mounted on aluminium brackets. I'll actually be replacing one of the factory panels and notice they only use adhesive. M6 bolts make sense for strength, my concern is they introduce an entry point for moisture.

Can I put a puraflex40 Panel on my roof?

Puraflex40 on my old panels with those same plastic feet - surfaces must be clean but roughed up which will vary depending on what your outer roof surface is currently. Don't mash the panel down onto the roof, 2mm thivkness of adhesive I recall was recommended. You achieve that by placing some small plastic strips into the adhesive on the feet?
