Hello everyone,
I am coming again with the same problem because I couldn't find the solution. I took from the example file the Solar collector Flat Plate water and I changed the solar collectors with Solar collector Photovoltaic thermal, following the example from the example files( Shop with PVT). As you can see from the, attached, error file, I have fatal errors that are not in the idf and there are fatal errors in nodes but there are the same nodes as the example. I am a new user of E+ and I would appreciate if anyone could give me a help
Regards
Christoforou Andreas
