Most people recommend not using wood at all in the structure to support the panels, unless it's well protected, like in the form of a house, but you are in a really dry area, right? reason for this is that your solar panels are going to outlive you, when your son is old there is a good chance that he will have to figure out who he wants to leave them to in his Will, you don't want to support them with something that will only last 20 years, but then again in Arizona you might be fine.
