I’m currently doing a solar radiation analysis for a canopy for a train station. The canopy will be filled with PV panels. I want to measure the solar radiation per hour for different angles during one winter and one summer day in order to see the peaks and low points.This will help me to optimize the angles throughout the shape in order to have a flat electricity production throughout the day/seasons.
I run the analysis using Ladybug and I found one method to break down the hourly information for each day and month. However, the outputs seem to be wrong. According to the values, a 0-degree angle is the best choice regardless if its summer or winter.
I am not quite sure if I used the right method to do this. I tried also another method but it did not work out (grey group in grasshopper). I would deeply appreciate any of your suggestions! I attached the files in case you want to take a closer look at the code. I downloaded the .epw weather file for Amsterdam from here https://energyplus.net/weather-location/europe_wmo_region_6/NLD//NLD_Amsterdam.062400_IWEC

This was my second attempt to break down the hourly values for a specific day. I tried everything but I did not succeed. I am open to any suggestions you could give me on how I can get out the hourly data for one specific day from this simulation. I attached files again because the units were in [mm] instead of [m] in the previous rhino file. Also, I deleted all redundant information from the grasshopper file.
Thank you in advance.

This is what you want?
This is giving you the amount of radiation [kWh/m2] for the period you choose. In this case, in your file, you defined some hours for one day.
If you want to select a different period from the analysis the process will be a bit different, so let me/us know.
Not really, I wanted to get the radiation values for all the daylight hours individually. Otherwise I would have to having to run the analysis for each hour separately. I don`t know if there is a way to receive all this information at once. Thank you anyways!
I suggest you to try this (i don’t have the time to check it):
At the selectSkyMtx (the first one) give a list of HOYs or an analysisPeriod for the whole year (for instance).
In this way you’ll get the sky matrix for each of the hours (this is the output of the component).
In the second selectSkyMtx you can give a HOY or a list of HOYs to get the results at the same time (grafting them). See image below.
