Is my solar hot water system overheating?

I have an evacuated tube split-system solar hot water system. The pump that circulates water between the storage tank and heat exchanger on the roof, has broken and can't be fixed until after the weekend. The question is, won't the evacuated tubes be damaged in the meantime, as no water is circulating through them to remove the heat? I imagine the effect must be like running a car with no radiator fluid.
