So I’ve tried to find a thread, blog, or article with a mathematical comparison but have some up short.
Let’s say someone wants to run a string facing due east and a string facing due west. Rationale “extend hours of production off battery”
For the south array it was fairly easy to determine optimal angles of tilt.
For east/west it seems there are two opposing options.
1: extreme vertical tilt (60 to 90 degrees). This would allow the earliest and latest energy absorbtion at the expense of mid day and later/earlier collection once the suns angle is beyond panel visibility.
2: shallow tilt (15 to 30 degrees). This would allow early and late collection due to the suns direction on the horizon, but a less direct angle. It would however allow production for a longer duration.
So: is there a general consensus on which is “better” in an absolute sense, assuming environmental obstacles are the same for either
