My settings/configuration:

• Pla plastic
• 10% infill(if you want the stand to be a bit stronger you can probably increase it to 20%)
• 15 mm layers
• Support on build plate only

Background:

This is part of a school project, I have made it for a presentation in school where I will talk about just solar panels.

Tips:

I would recommend trying to print it as if the part there the solar panels stand on almost stand up to be able to use as little support as possible. You could make it so the plate is standing down on the ground although I would say that could make it have worst quallity.
