For my largest project to date I will show you how I built an off-the-grid solar powered workshop using products and materials from Home Depot. I started with a pre-fabricated shed from Tuffshed and added photovoltaic panels and a battery system that would allow me to run power tools as well as lawn and garden tools off of renewable energy. I got my solar panels in a kit that I bought from Home Depot. I used four 6-volt batteries to create a storage system and I am able to power both corded and cordless tools from them. The total cost of this project was $7500 and took about 20 hours to build.
