Hi,
I have built a 3,9 kWp off-grid solar system in Q1. LiFePo-Storage is currently on the build. I want to store PV energy over the day and charge my Tesla overnight.
As my battery is not ready yet the hybrid inverter is not able to run, so I currently test with 2/3 of the panels with a SUN GTIL.
The orientation of the panels is 15° upright and in the direction of South-East. The panels are installed on a roof of a carport.
This carport is next to my house, accordingly my house shades the panels in the morning.
The 12 panels are wired 4P3S.
This is the current grouping:
Currently only panel 1-8 is connected to the SUN GTIL but as soon the battery is completed the whole system will be connected. Now I found out that my house' shading is affecting the productivity in the morning. Panel 1,3,5,7 is free of shading first.
Will it increase the productivity if I switch over to group 1,3,5,7 parallel and 2,4,6,8? (9-12 will stay as it is as 10 and 12 are the last panel free of shade).
Attached you will find a picture looking from 2nd floor onto the panels and a picture from my garden to the carport.
Thanks for your help and Greetings from Germany
