Homemade Solar Panel Stand! Easy DIY Stand (for my DIY solar panel). made using a few pieces of (2×2) lumber. rugged and sturdy. fully adjustable. total cost $7.67. note: the stand can easily be lengthened (for holding additional panels). for each additional panel you want to add, just add approx. 19″ to the length of the back brace and the 2 horizontal pieces of the main frame. the design of the frame allows it to be expanded to hold a minimum of 3 panels. here’s the link to the video on how to build the solar panel https://youtu.be/BoM7KlyhOvg
