What angle should my panels face?

The best angle of the panels varies according to the installation location. Refer https://solarcalculator.com.au/solar-panel-angle/ Another theory is that the angle should be a little bit less than the latitude of the location, refer https://www.solarquotes.com.au/blog/solar-panels-tilt-angle/
North - Ideally, solar panels face due north to receive most of the annual daytime sun.
East - receive almost as much sun as north-facing panels (85-90%). If you’re often home during the morning, east-facing panels will help you take full advantage of the morning sun.
West panels - also receive about 85-90% of the sunlight north-facing panels enjoy. They’re especially productive in the afternoon and early evening.
South - In the southern hemisphere, south-facing panels receive relatively little sunlight, so are usually not recommended.
