when is the sun at it's highest point
Noon Solar noon is when the Sun transits the local celestial meridian; this is when the sun is at its highest altitude in the sky, at 12 noon apparent solar time. The local or clock time of solar noon depends on the longitude and date.[1]
Sun path In the Northern Hemisphere, the sun path near to the winter solstice (November, December, January) rises in the southeast, transits the celestial meridian at a low angle in the south (more than 43Â° above the southern horizon in the tropics), and then sets in the southwest. It is on the south (equator) side of the house all day long. A vertical window facing south (equator side) is effective for capturing solar thermal energy. For comparison, the sun path near the winter solstice in the Southern Hemisphere (May, June, July) rises in the northeast, peaks out at a low angle in the north (more than halfway up from the horizon in the tropics), and then sets in the northwest. There, the north-facing window would let in plenty of solar thermal energy to the house.
