Hi there! 

I'm pretty new to this so sorry if this topic has been beaten to death already (have tried searching but can't quite find the exact things I was looking for):

Does anyone have any data on how a Winter (UK) optimised EV collector (I think about 70 deg angle?) would perform in kWh per square meter / collection of tubes?  I know it can't be precise but just a general figure would be good...

I've attached a picture of some general output figures per month of a 20 tube system (47mm) from Navitron, but I assume they are performances based on a Summer optimised angle?

Thanks in advance!
