Here's a rough guide as to how you might adjust the solar panels yourself to maximize their solar power output:
* Early February: set your solar panel at the same angle as your latitude.
* Early May: set your solar panels at your angle of latitude minus 15 degrees.
* Early August: set your solar panel at the same angle as your latitude.
* Early November: set your solar panel at your angle of latitude plus 15 degrees.
