I'm trying to use EnergyPlus to see how much electricity and hot water a Photovoltaic-Thermal system in EnergyPlus would create. I've been using the IDF editor in EnergyPlus to do this, because I haven't been able to figure out how to implement the PVT system in OpenStudio. So far, I've taken the SolarCollectorFlatePlate example file that came with the EnergyPlus download, and modified it to instead use the SolarCollector:FlatPlate:PhotovoltaicThermal object instead. However, the simulation only passes water through the PVT cooling system for the first few days of the annual simulation, and then it tapers off after a week or so. I can't figure out how to get the simulation to consistently pass the same amount of water through the cooling system. Can anyone help me?

It is difficult to formulate an answer with this level of detail. The better example file to use as a starting point is called "ShopWithSimplePVT".
