Interesting facts about Seasons

Distance to the Sun
-Northern hemisphere Winter: Earth is closest to the Sun
-Northern hemisphere Summer: Earth is farthest from the Sun

Length of day
Days are longer during the Winter than in the Summer. I don't mean 'daylight hours', yes those are shorter during the Winter, I mean the time from Noon to Noon.

The Earth spins around it's own axis at the same rate all year around, however, the Earth orbits faster when it's nearer to the Sun, hence it takes longer for the Sun to return to the highest point in the sky. When viewed from above the Earth spins CCW and orbits CCW.

Because of this the Sun actually travels angularly faster across the sky in the Summer, but stays up longer because it travels along a longer arc than in the Winter.

Area facing the Sun is a major factor in Solar energy collection (and Seasons.)

I measured the power collected from a small solar panel.

When always facing the Sun:

-When the Sun is straight up 5 watts was collected.

-When the Sun is 60deg from zenith 4 watts was collected.

Not a huge difference from 0 to 60deg.

However if I tilt the small solar panel even when the Sun is straight up the power is greatly affected. Tilted so much that the area facing the Sun is halved, the power halved as well. (power breakdown: voltage remained around 24v, it's the current that changed.)

Same deal with the north and south hemispheres.

-In the Summer time more north hemisphere area faces the Sun.

-In the Winter time less north hemisphere area faces the Sun.

Not quite the extreme altitude of the Sun, but same principal in these examples:

Baja California takes up alot of screen space (so greater solid angle) during the Summer

Baja California takes up very little screen space (so less solid angle) during the Winter
