This is a small question, and if there's some place I could have been looking (documentation?) for the answer instead of bothering folks on here please do let me know. I'm trying to model a system that uses solar thermal for space heating as well as domestic hot water.  I'm currently trying to do this using design A3.2 (DHW system with heating buffer tank and external heat exchanger).  I clicked on the design assistant.  I click on the definition of consumers tab on the left.  Then I click on the space-heating...lets call it a sub-tab under where it says "definition of consumers".  There's a check-box where it asks if the space heating energy requirement is known, and I click on the check mark because yes, it is.  The bottom box asks for heating energy requirements, in this case in BTU/hr.  That's where I'm unclear.  What is the context of this?  Is this my average heating requirement for the whole year, expressed as kBTU/hr?  Is it my peak heating energy requirement on the worst day of the year?  Is it the average requirement for the worst month of the year?  Thank you  

Hello users, A few day  I search how to create simple east - west  system on flat roof or terrain, but in  menu module mounting I can't find this option. Pls help me.

How you create east- west system . I search this option few day. Please show me how to  create simple east-west system.

Hello! While designing a PV system over a 3D OBJ (captured in drone deploy and exported on ReCap) the result of the simulation was 15000kwh/year. It is a system surrounded by 2 buildings, with lots of shading. After the system was installed, the efficiency was aroung 30% of the simulated values. Reviewing the 3D simulation, I noticed that the shading simulation was incorrect, with values around 3% where it should be higher. So, I designed walls to simulate the building walls, and turns out that the simulation result became very close to the actual generation. Se attached pictures with and without the walls. It seems like PvSol cogeneratedBy_react-csv (2).csvnsidered the actual 3D model as "transparent" or something like that. What is the reason and correction for this behaviour?

Hallo, das war ein super Tip, vielen Dank. Bei mir hat geholfen, den Haken bei "Außerkraftsetzung der hohen DPI-Skalierung" zu setzten (Verhalten bei hoher DPI-Skalierung wird durchgeführt durch die Anwendung). Danach mußte ich PV*SOL neu starten, damit die Änderung wirkte. Viele Grüße Bernd
