Solar Electricity Handbook - 2015 Edition: A simple, practical guide to solar energy - designing and installing solar PV systems.
The Solar Electricity Handbook - 2015 Edition, is a simple, practical guide to using electric solar panels and designing and installing photovoltaic PV systems. Now in its ninth edition, the book assumes no previous knowledge of solar electric systems. The book explains how solar panels work and how they can be used. It explains the advantages of solar energy and the drawbacks that you need to take into account when designing a solar power system. As well as explaining the underlying principles, it provides a step-by-step guide so that you can successfully design and install a photovoltaic solar system from scratch. Unlike many guides, The Solar Electricity Handbook explains the principles behind the technology, allowing the reader to design solar energy systems with confidence. The book has been used all around the world, designing systems as diverse as providing entire African villages with electricity, powering vending machines, building grid-tied systems for housing, building a one-off solar electric car and creating lighting for an allotment shed. Accompanying the book is a website that provides solar calculators and online tools to help simplify the solar design process, including a unique database of sunlight values for every major town and city in every country in the world that has been created specifically for this book in conjunction with NASA. Readers can also get in touch with the author directly to ask questions and get further support with their solar projects. Why buy the Solar Electricity Handbook?
