Title: Which side of a house will get the most sunlight?
Question: Which side of a house will get the most sunlight?  Articles on the internet seem to have conflicting answers. Is this because it is dependent on location?

Answers:
sents: text: In general, it depends on your location.
text: In the northern hemisphere, the south side gets the bulk of the sun, because the sun is in that half of the sky.
text: But if you are on a hill, or have a hill to the east or west, it can significantly shorten your solar 'day'.
text: Additionally, if you are in an area that tends to get morning fog, east-facing will get less effective sun than west-facing, because by afternoon the sun will have burned off the fog.
text: Finally, elevation matters.
text: Higher floors will get more sun because they "see" more of the sky.
text: So in general, the south-west of the house will get the most sun, with upper floors receiving more than lower floors.

sents: text: This question depends on context.
text: I could say the north side but for all I know the north side of your house has no windows.
text: It also depends on geographic location.
text: Where does the sun rise/set.
text: Do you have any trees/objects near your house that would obstruct light?
text: There are varying factors here to say the least.

sents: text: I believe that in the northern hemisphere, it's always the south-facing side, and north-facing in the southern hemisphere.
text: Wikipedia's article on Seasons has a few nice images showing this.

sents: text: The sun rises in the east, swings south throughout the day, to set in the west.
text: Depending on season, "east" may be slightly ESE in deep winter to E in mid summer to ENE in late fall (northern hemisphere).
text: Of course it's the earth, not the sun, that is moving.
text: Which side of your house gets the most sun is dependent on local geography and site layout (in a valley, on wide open plain, large shade trees, high on a hill) but the earth's rotation and season of year is constant.
