The angle of the solar panel is important inorder to absorb the most energy.
To buy a custom make one will cost a bomb, but here is one easy way to make it with card board, a bolt & 3 nuts.
Step 1: Determine the dimension
1- Measure the height of the stand base on the longest edge of the solar panel.
*Measure so that the stand is in the middle of the panel.
2- HALF cut the bending edge...Do NOT cut through, it is meant to bend.
3- Tape along the HALF cut area so as to prevent further tearing.
4- Measure the location of the hole for the bolt to go through.
5- Use a hole puncher to make the 2 holes (for M6 Bolt)
