Then you didn't do a good site survey before installing your panels. You should have considered that before installing panels.
At my request, 32 of my 48 panels face south west. On a per panel basis they produce about 91% of the 16 panels facing south, but they peek about 4pm during the summer. I know this because I have monitoring on my system that records energy production and panel diagnostic data every 5 minutes, and 10+ years of data sitting in PostgreSQL database.
