Hello, 

I'm new in Grasshopper world, and I have to simulate a building covered with PV panels. So I need to add the information about Sunpower E20 Solar Panel Cell to the material list. I added the script below on the material list and also the calibration file on the Radiance library. But this material is still not showing up on the material list, what can I do to fix this problem? There is other way to add the material to the list?
