I wanted to understand why the sun positions in the morning and evening did not agree with my mental model of sun position.
Specifically I live south of the tropic of Capricorn, and yet the sun rises and sets South of my position.
Turns out that although the sun is always north of me -at midday- , because of the angle of inclination of the earth, for gold the year it rises and sets south of me.
This means that my solar panels should lie flat, not point north, during the summer half of the year. I adjusted them, and am seeing improved generation during the morning and evening.
