I learned SO MUCH on solar panels. I've never bothered to wonder how they get placed where they do, and in what direction and how installer's determine to what degree a solar panel should be placed. So the equinox, which always falls on either March or September 21st at noon every year creates the Zenith angle (a Zenith angle is the angle in which the solar panel should be placed to get the most sunlight on average) And specifically, at this date and time, the Zenith angle will be the same as you latitude (so for Bangalore it is 12.9 degrees), and this would then change by 23.5 degrees each way depending on the season and your location/latitude. We learned so much more on solar constant and solar irradiance and solar insolation and a lot of other stuff that I won't bore you by writing, but it was really great to learn for the sake of learning and not for any particular class or exam. Also, this is completely unrelated, but I just tried filter coffee, which is a really strong coffee often served in small servings that people in India drink and its the most amazing coffee I think I've ever had in my entire life holy crap.
**All of the solar panel information could totally be wrong, I just learned it all today in mass bulk.
