Solar panel energy and electricity generation


Using ladybug radiation analysis I have been able to generate the energy produced by multiple and singular solar panels. I created a bunch of panels and set that as my test geometry. Each individual panel has a test point in its center. So by multiplying the total radiation results by an efficiency, you get the approximate energy produced by all the panels (0.23 in this case):

What you can also do is select any panel and obtain that panels energy output for the year by setting it as a surface in grasshopper, obtaining that panels incident radiation in kWh/m2, multiplying by its surface area and efficiency:

I was wondering if grasshopper had other plugins or ways, to maybe more accurately generate the energy and electricity output produced by solar panels?
