I should have found this plugin earlier. I just started using it this week on passive and active solar design models for green built homes. I have made some models for solar space heating panels and used them in my SketchUp designs, and looked at solar radiation on windows and solar gain using a little math to devise Representative solar gain figures for windows.

What I want to say the most about this plugin is that it is way easier to use than some of those plugins for use with coupling DOE and NREL software with SketchUp. You can get started right away and get that data you really want for designing solar homes.

I am writing about my experience with this plugin in my models and some of the devices I have design with it such as solar space heating panels. https://solarparadigmdesign.wordpress.com
