unexpected warning ...from-grid tariff is not valid...

[R040l]

I've got an always present warning message "The selected from-grid tariff is not valid for the country in which the climate data record is located"

However, I have selected
  - Climate data country Netherlands: Eindhoven RNLAFB NLD
  - Tariff country Netherlands (there is only one possibility)

What could be wrong?

Hi Rob,

here as well, a project file would be handy in order to see what is going on there.

Thanks a lot, kind regards,

Hi Martin,

While unrelated to my other topic I posted (Flat roof panel shading not included), but the project I just shared there with you shows this behaviour as well.

Hi Rob,

I just wrote an answer to your questions in the private message section. If you allow, I'll post it here so that the other users can read it as well.

Kind regards,

Yes go ahead and post so that anyone can learn.

So I will post our private conversation here (in extracts):

Dear Rob,

thank you for sending the project file. The row-to-row shading is calculated only in the 3D mode. As for the warning message for the from-grid tariff: The climate location is set to Eindhoven, Netherlands, whereas the from-grid tariff is for Germany. You can either create and select a tariff for the Netherlands or just ignore the warning message.

Hope that helps, kind regards,

Martin

The shading I find a very important part of simulation because it could show me the penalty on sub optimal setup.

The photoplan editor I found not usable at all. video help in buggy flash is not of this time. I have not yet managed to get anything 3D. Is import/export from Sketchup possible? Then it would be easy to get dimensions, orientation and obstructions correct.

Street level photos can work for tilted roofs, but not for flat roof installations. My building is too new to appear in Google maps.

The grid tarif system I do not really understand and is of less interest to me. Nevertheless, the info box clearly states "Country: Netherlands"

yes, shading is a very important part of the simulation. In the 3D environment the diffuse and direct shading is calculated with a high level of accuracy. Yes, you can import 3D models from Sketchup (and other 3D modelling software) in PV*SOL.

 

As for the tariff problem: The net metering tariff is for the Netherlands, that is right, but the from-grid tariff (the second one) is for Germany:

Hope that helps, kind regards,

This tread is about the warning about grid tarif country, so lets concentrate on that.

For the Netherlands, it is the _only_ choice that can be made, afaik. The German "Gebaudeanlage"  did worry me also a bit that this might not be right, but there is no alternative. But that is not the only part where I came across untranslated print, which is easily forgiven, for this fine piece of software with such large amount of data that is never going to be complete however hard you guys work on it.

Being a technical guy, the financial analysis part in not my prime interest and the large array of possibilities with unknown effects and limitations, result in me not being too bothered about possible incorrectness on this area.

Dear Rob,

sorry for the late reply. What I wanted to say is that the feed-in tariff is not the problem here, but the from-grid tariff. The feed-in tariff is for the Netherlands, that is right and correct. The from-grid tariff however is from Germany and that is why the warning message appears.

Kind regards,

Martin
