How much energy you can earn from a solar panel, depends on how intensive the sun shines on the panel surface.
Therefore, you want to orient your panel towards the sun. With an accurate orientation, you can easily double you energy harvest of a day.
But sometimes it is hard to find a spot where the panel points towards the sun. At the latest some hours later you have to find a different spot because the sun has moved.
The video gives you an overview about the adjustable stand. In addition, I visualize how the sun shines on the panel during the day and in spring, summer etc. (English subtitles)
As I explain in my blog entry https://ewap.ch/solarpannel-zur-sonne-ausrichten/ I do not charge my smartphone directly from the solar panel. I like to use my phone during the day and charge it in the evening.
So, I charge during the day my USB power bank and during the night my phone from the power bank.
From one day it I get one full charge for my phone or a 50% charge for my tablet.
The Parts are designed to print in a certain orientation. Check the pictures to get them oriented the right way.
The hole in the T-shaped part is designed that it can be printed horizontally without any support material. See the blue surfaces and cross-section to understand my trick.
Cut the 12mm Tube to length according to your panel.
Before we glue the corner parts to the tube, we push the T-shaped part on the tube. No glue on this hinge. With the two-component adhesive, we can now glue the corner parts to the tube.
To avoid any support material on the horizontal holes, I optimized the geometry.
