This tutorial shows you how to align a solar panel to recieve the most sunlight possible for a given latitude, using Ladybug's sunpath component and Grasshopper's vector cross product. Ladybug and Honeybee are open-source Grasshopper plugins designed for
- [Instructor] In the last video…we calculated the average sunlight vector…for this specific location…and I'd like to use that information…to figure out the best angle to mount a solar panel.…So I'm starting with the Rhino file Ladybug sun path.3dm…and I've gone ahead and turned on this…solar panel layer.…I can see right down here is my proposed solar panel site.…I've also got the Grasshopper file…0085 Ladybug sun path average finish.gh open…and to help me figure out the correct rotation…for my solar panel…I'm going to use a vector operation called the cross product…and that calculates a vector that's perpendicular…to two other vectors.…
Now I have this one vector already,…the average sun position,…and I'll need to calculate at least one other vector…to help get my mounting angle.…So let's go back to Grasshopper…and we'll setup some notes to help us as…we tweak our algorithm.…First thing I'll do is…just right click on the sun path component…and let's disable preview on that.…I don't need to necessary see all those sun positions.…
