(User Info)

Leaving the panel driving a load results in less heating of the panel than either opening or shorting it.  The power that would drive a load heats the panel instead in either of the don't-drive cases.

Since the power to the load is about 15% or so of the total sunpower absorbed by the panel - and all the rest heats it, too - it doesn't make a lot of difference.

So since you've already got a dump load hooked up I'd say leave the panel driving the load and let it run slightly cooler.
