Hi Brian
As long as the hardware is stainless, I wouldn't worry about it.
Standard fare on sailboats is stainless hardware on aluminum, and they
see a lot more nasty moisture (salt water is bad enough, but the stuff
in our harbor would literally make your hair fall out...). You aren't
likely to be throwing salt about, so no worries!

I'm on the point of ordering a solar panel installation. The PV panels
are set into an aluminium profile framework, held together with
stainless steel (presumably 18/8 alloy) screws etc. The installation
has
a projected lifetime of ~40 years. In this timeframe, I'm a wee bittie
worried about dissimilar metals, exposed to the weather, causing
corrosion. Granted the surface area of the Al is ginormous, compared
to
that of the hardware, so that the corrosion will not be localised.
The weather here is typically 9 months hot and dry (say, 25 - 47°C, 45
-
20% RH resp.), aggravated by direct exposure to the sunlight. The
other
three months are cool with intermittent heavy rain (say, 0 - 25°C,
45%++
RH).
Would it help to paint onto the hardware (not the profiles) an epoxy
coating, after the screws have been tightened, to reduce the risk of
long-term corrosion? If so, what type? How does the epoxy stand up to
UV
exposure over the years?
TIA
Brian
