I'm building a ground rack for solar panels. Something similar to one described here.
They use corrugated polycarbonate roofing panels as backing for the panels. I found similar metal panels that are priced a bit better and would probably be stronger and longer lasting.
My only concern is that metal panel would work as a radiator dissipating the heat from the solar panels. Is that something to be concerned with? The rack will be open to the wind so I fear it might make difference.
Anything else I can use for this purpose?
