Copper on aluminum

2006

Sirs
I want to build a solar panel using copper pipe with an aluminum collector plate.
Will I have any long term problems with these two dissimilar metals being in contact with one another?
thanks in advance,

Simply don't let them touch each other and the problem disappears, Maurice. Use a short length of hose or a dielectric union between the aluminum and the copper.
