Hi adding a battery monitor to the system has been useful with the phone as a handheld and after watching the panel output power I think I want to experiment with a radial or curved array where basically I tilt the outer row maybe by 2” to anticipate the rising sun a tad. Out of the 8 panels in 4x2 I would be tilting two east and two west. Any info out there about results? Seems subtle enough to be useful. Have to re mount anyway for maintenance so the small return fo labor is a non issue. Moveable panels not an option. Thanks guys
