How much more energy do you produce if you face your solar panels towards true south rather than magnetic south?
In this video, I share the results of an analysis I conducted to find the best direction for solar panels to face.
I used PVWatts to run an analysis for over 200 cities around the world. I calculated the annual production of a 10kW ground-mounted solar array at each location — once using the magnetic azimuth and again using the true azimuth.
I then ran a similar analysis for 100 cities around the United States. Lastly, I averaged the results.
I discuss my findings, as well as a way to find the optimal azimuth angle for solar panels, no matter your location.
