Title: Excellent technical resource
Review: This book carefully derives the formulas for a wide variety of solar applications. The trig formulas are not derived but to do so would require a whole separate textbook. A fair amount of background is needed to digest the material presented. The figures and diagrams are a good supplement. There are typos, so one should know how the material is derived, and not just use it blindly. Overall, its one of a kind in its field.David Collins
