Title: Not much depth
Review: The 70 pages of solar data was a definite waste of paper. I just went to the referenced website and downloaded the data plus additional temperature data for my site so I could better estimate panel derating during the summer. The book mentions the need to derate expected panel performance in several places but doesn't provide the data or worksheets to do this. I also found the discussion on wiring dissimilar modules to be misleading and incomplete. My impression of the book is that is was a compilation of notes from several different instructors and probably makes a good textbook/workbook but definitely falls short of being a good stand-alone installation manual. The best design and installation information I have found is free at the Sandia Labs website (www.sandia.gov/pv). This and other websites and resources are listed in the book. I did learn a few things reading the book and I expect the worksheets may come in handy.
