Foundations don’t have to be expensive. I show all the details of how I built my own DIY solar panel ground mount. It took about 6 hours and a lot of hard work, but was nearly free!. No special tools or special equipment is needed.
I’m using 3/4″ crushed stone, and used railroad ties. This is a great way to recycle a waste product.
