Plots: Cannot run solar potential plots unless all technologies are simulated

[amraladdin]

I ran the solar energy potential for technologies PV1 and SC1 only. When I tried to run the plots for the solar energy potentials, I got the below error. My interpretation, and @martin-mosteiro as well, is that the tool is trying to find the CSV file with the Evacuated Tube solar collector (SC2) results.

@JIMENOFONSECA @shanshanhsieh sorry for assigning you directly, but this is kind of an emergency.

Hi @amraladdin , at the moment, you will have to run all the solar technology potentials to execute the solar technology plots. This means you have to run:

1. PV
2. SC1, t-sc-supply =75
3. SC2, t-sc-supply=150
4. PVT

I am planning to disaggregate them, so you can run the plot with the technologies you have simulated, however, it will not happen for the test run. sorry about that.

[martin-mosteiro]

In that case, @amraladdin we will need to supply students in the test run with the results of the solar technologies potential since we won't have time to run all of the potentials during the test run and @shanshanhsieh has confirmed her exercise does involve running the solar technologies potential plots. So I'll create a separate issue asking everyone to upload their results.

[jimenofonseca]

@shanshanhsieh is there a way we can find the most efficient way to run the tools? maybe by changing to only roof-tops and low temperatures? Is it possible that we run optimisation without having to run all technologies? @BhargavaKrishnaSreepathi can we do this? it would make possible to actually use the tool during the executive course.

[BhargavaKrishnaSreepathi]

It is possible, but I will not suggest to do it, as it requires changes in multiple places in CEA, which needs to be followed up by testing process. Keeping the time in consideration, I would refrain from this. One way is to pre run the technologies for each case study and have them. As per my understanding, we just show them the simulation of one technology, namely PV and provide the results for the other technologies (as PVT, SC1 and SC2 take significant time to run).

[jimenofonseca]

What about if you get SC2 and its files as zero when they are not present? that will be a quick fix right?

[shanshanhsieh]

I started working on it in i1244 (will be ready to merge today)

1. for the plotting function, it will only plot the files that are simulated
2. for SC2, we can run for roof tops, but the rest of the technologies can still consider walls and roofs
3. in the case of cooling, PVT is not required, i thought you made a quick fix to bypass it last time in the individual evaluation branch, @BhargavaKrishnaSreepathi ?

[BhargavaKrishnaSreepathi]

yes @shanshanhsieh, as PVT is not being used, we can make sure that it is not necessary to run it, just need to add a conditional statement in cea\optimization\optimization_main
