I went from doing a plumbing project to mowing the grass and had an epiphany while trimming around all the solar panels staked into the ground at random points in my landscaping. I can make a simple PVC pipe solar stake bracket!
PVC Pipe solar stake bracket
Most of us have these cool solar lights in our landscaping, some of them are all wired together to a single solar panel and battery pack. I always knock them over or have to trim around them after I mow.
I used some left over PVC pipe, drilled a small hole on one side and a larger hole, big enough for a screw head and screw driver, in the other side.
Now I can use a couple all-weather screws and mount these solar panels up off the ground, in more convenient spots.
This is a quick project, and you may already have everything you need.
