Error : Index Out of Range - Ladybug/ "Photovoltaics Surface" Component

Hi everyone! Thanks to these awesome forums here, this is my first question after months working with GH and LB/HB!
I have a problem with the PV surface component. I don't know what this error (Index Out of Range) means here to be able to figure out what is causing trouble in my model. I would be really glad if someone could help me out with this.

Hi Omid,

The reason for this error is a bug with calculation of tilt angle.
It has been fixed in March this year, while your "Ladybug Ladybug" component is from January.

I replaced your "Ladybug Ladybug" component with the newest version.
The error should not appear now.

Btw. the shape of that building looks interesting! It would be nice if you would post a screenshot of the building facade.

Thanks a lot, thanks a lot, thanks a lot,...!

I would be grateful if you would attach the photo of your building once the project is completed. It looks interesting.

I'm designing a facade with translucent disks and some parametric circular PV panels on them based on the solar radiation that each disk gets during the year to avoid solar heat gain and at the same time get ACenergy from it.

I was trying to calculate the power output on rigid disks and on dynamic ones to find out how much would be the difference if they had a dynamic system to be able to track the sun.

Thanks to you I am able to do it now!

Hi Omid,

Interesting work! Actually I am trying the same, make a comparison between dynamic an static panels. I was wondering how you make this model "dynamic".

Could you share this?

Thanks alot!

Milan

Hi Milan,

Until Omid answers, you can also check this topic, and a couple of example files in there. Specifically this one.

It provides analysis of three "dynamic" PV system: Horizontal single axis tracker, Vertical single axis tracker, Dual axis tracker (horizontal and vertical) and their comparison with regular fixed PV system.

Hi Milan!

Unfortunately I could not find a way to calculate it dynamically (Guess it's not possible), So I calculated the results for different exact times during the day, with a simple number slider for the hours and the rec component for saving and adding the results to compare the two (Dynamic and Static). I did it for different days in different times of the year.I know It was not the most precise calculation but it gave me what I needed for my presentation.

I would still be happy to know if there was a better way to calculate the difference.
Let me know if you found one!
