We love this book. Written for people in remote places without handy hardware stores, it includes hundreds of wonderful graphics and charts that make it simple and easy to design, install, trouble-shoot, and maintain solar electric systems. Great cost-saving ideas like how to make your own mounting structures and manual solar trackers. Not code-oriented but extremely practical.
