Hello, I am using FloorSpace editor in OpenStudio instead of SketchUp and I want to implement photovoltaics in some surfaces in my building. Its possible? Does anyone know the steps to do so?

Beyond a dedicated measure (adding PV to a model) or the SU Plugin PV user script, you're left hacking an OSM as suggested in option 2 here (or similar). Not great, but manageable. Would love to learn if anyone has maintained a PV measure (if so, I'll convert my answer to a comment).

EDIT: Your OpenStudio PV objects seem to translate (to EnergyPlus) just fine (different weather file):

I see the objects in the generated in.osm, in.idf. I'm not seeing related errors in the .err file, although you do have notable unrelated errors to fix (e.g. subsurface with 6 vertices). Otherwise, I have not gone through inputs vs results to validate your entries. Yet apart from that, it looks OK to me.

I tried to hack the .osm file as suggested but when simulating the file is reverted to the model without PV. Are any additional steps necessary?

Could you share a public download link to the .osm file?

Please see if you can download

See the recent edit to the initial answer. Seems OK to me.

I ran the program again and now I got results from the PV production, with differences from your results, I assume due to the use of a different weather file. Thanks it solve my question.
