Step-by-Step Setup

Unfold panels fully: Ensure hinges lock flat to expose the maximum surface area.
Adjust tilt angle: Use the kickstands at 30°–60° depending on season and latitude.
Face the sun: Point directly south (Northern Hemisphere) at noon for best results.
Keep cables short & thick: Minimizes voltage drop.
Monitor output: Use a power station display or multimeter.
