Solar panel, power loss!!!!!

[packard]

Hi all, what consequences is there to happen to the solar tubes in a house if the power goes off? If you have no power to work the pump is the heat from the tubes just going to build up and crack the tubes or have you to leak the water from the tubes?

The water will heat up beyond boiling point beacuse there is antifreeze in the system & should blow off steam through 7 bar pressure release valve on the system
