Fundamentals of Renewable Energy Processes Book

It is a good textbook. It assumes that the reader has some knowledge of physics (at least undergrad) and mathematics. So, if you want to read it, make sure you are prepared. Read some optics and some material science first. It is not a technical manual as some people seem to assume. It includes technical information, but it is a physics book. The main thing I disliked was how the plots looked. Some were hard to understand because it wasn't clear what was what. I didn't see what people were complaining about until I came to plots in which I had to guess which line was what colour.
