Effect of Solar Panel with SS-316 frame instead of Aluminium frame

One of my project at Iceland, I need to use SS-316 frame to protect from corrosion, instead of aluminium frame in solar panel.
As there is difference in thermal conductivity of SS (50.2 W/m.K) and aluminium (205 W/m.K) as a heat sink in solar panel.
If I use SS-316 instead of aluminium, what will be the impact of it???

    If this is a solar PV panel, I doubt it will make much difference.  The glass - frame interface does not conduct much heat.

    However, the thermal expansion would be different. you may want to look up the differences between glass - aluminum and compare that to glass - SS316.

    Stainless should be a "better match" to glass vs aluminum:
