lots of spelling errors, did anyone proof this? also, i’m pretty sure all the graphics were originally color, but there are no color slides in the book so many of the graphs are difficult to interpret.the flow of the text is difficult to learn from; the go from basic concepts “what is ac? what is dc” to using many technical terms with out any explanation.the person or group who wrote this obviously had a wealth of knowledge; too bad they are poor communicators.
page two pretty much sums up the entire book. whoever wrote this uses paragraphs to say something a normal person could say with two words. it is the most useless and overly confusing handbook i have ever read in my entire life. a dead monkey could teach you more about solar panels than this useless glued together chunk of paper.
