In the first IDF you posted (nyololo.idf), there were no solar panels and the EPlus aborted the simulation because you have used the same zone name for the open area at the end of the building, as the zone in the middle section of the building.
SketchUp did not report any warnings.
If you have not corrected those duplicated zone name errors, the EPlus may not simulate.
What is the file name of your latest IDF?
Run the solar collector example to understand how the tank heating is controlled. The circulation pump would operate only when the temperature of the collector is high. The current tank size is 0.3 m3, I think. This is a common 60 gallon size. Yours is 2 m3 = 2000 liters. You may need a larger tank than this.
The set point for the tank is about 85°C and is throttled down to 65°C for domestic hotwater use. You may remove this section. The instantanious electric heater may also be removed. The full description is in the I/O Ref. manual.
The use side outlet and inlet to the circulation pump is where you will cut and connect to the building demand section of the water loop which should have the baseboard or a cooling coil. You can have a gravity operated pumps and fan, as you do not have electricity to run tem...

firstly thank you for your answer!
I am already studying a lot of example files (PlantLoadProfile.idf, SolarCollectorFlatPlateWater.idf like you said, ...) and I succesfully put in my idf the solar collector and a coil but I can't find the way to create my 2,000 liters storing barrel and the way to link these 3 components
