how to build a photovoltaic system in energyplus

asked 2016-04-08 09:01:11 -0500

I'm trying to put a pv system to the facade, and get the produced electricity, I wrote the IDF as following, but I can not find the variable outputs in the cvs file. What is the right process for this?

@Yi I can't see the whole file. Maybe it's just me,but when I click (more) at the bottom, nothing happens. Can you post a link to the file instead?

For the output variables, you have to run the simulation first then change the output variables in E+ or use OS measure.

If looking for PV energy generation, NREL PVWatt's calculator is a good choice.link text

If you try to see how to model with OS or E+, please refer to this question link text

Hope this helps.

thank you for the answer, I did run the simulation first and add the output variables, but it is still not working. I think there's something wrong with my model, I copy the section from an example and simplified it. I don't know if something is missing to build a functional system.
