solar panels roof
What direction should solar panels on the roof be directed for maximum daytime heating?
If a construction company were to build a solar heated home in middle latitudes in the Southern Hemisphere.
It would be best to ask a professional installation company, or other folks in your area with solar heat, for what works best.
It will be something west of north, since the afternoon air temperatures are presumably higher than the morning temperatures. If the temperature is the same all day, then due north.
In the northern hemisphere, I seem to remember someone saying 220 degrees southwest was the best for them, but that’s an individual experience. Who knows, maybe they have morning fog that burns off later.
