This book is about making solar electricity available to people in rural Africa. It describes how, with guidance from an electrician, anyone can adapt a solar electric system to their own needs. Thirteen chapters cover the following essential solar electric topics: estimating local solar resource; solar electric, battery, and charge controller choice and technology; choosing lamps, appliances and small tools; low voltage wiring principles and practice; planning, installing and maintaining a system. The revised edition has added a new chapter with information and resources about the solar electric industry in East and Southern Africa. The book also includes planning worksheets, wiring guides, meteorological information and well-illustrated examples.

This book provides a comprehensive overview of the technology behind the pico-solar revolution and offers guidance on how to test and choose quality products. The book also discusses how pioneering companies and initiatives are overcoming challenges to reach scale in the marketplace, from innovative distribution strategies to reach customers in rural India and Tanzania, to product development in Cambodia, product assembly in Mozambique and the introduction of ‘pay as you go’ technology in Kenya. Pico-solar is a new category of solar electric system which has the potential to transform the lives of over 1.6 billion people who live without access to electricity. Pico-solar systems are smaller and more affordable than traditional solar systems and have the power to provide useful amounts of electricity to charge the increasing number of low power consuming appliances from mobile phones, e-readers and parking metres, to LED lights which have the power to light up millions of homes in the same way the mobile phone has connected and empowered communities across the planet. The book explains the important role pico-solar has in reducing reliance on fossil fuels while at the same time tackling world poverty and includes useful recommendations for entrepreneurs, charities and governments who want to participate in developing this exciting and rapidly expanding market.

A revolution is ongoing in the field of small-scale energy solutions, which can enable lower impact on the environment, more robust supply and self-determination. Solar power and other forms of renewable energy sources, which you can implement to generate your own electricity, are growing quickly. Electromobility is transforming the car industry and transportation systems and can also play a role in your energy system. Electricity can be used much more efficiently than before, for example by using LED light, variable speed motor drives and efficient home appliances. Smart controls are available, sometimes with free open source software. All this opens up tremendous opportunities for energy independence, which is the focus of this book. The book introduces the reader to a number of renewable energy sources, to different options for storing electricity and to smart use of electricity, particularly in the context of small isolated systems. This is important because many renewable energy sources are weather- and season-dependent and usually require storage and smart control, in order to obtain a system that is completely independent of the electricity grid. In the book, overall system design is explained, including how to combine different sources in a hybrid system. Different system sizes and architectures are also covered. A number of real cases are described, where homes, businesses and communities have achieved a high level of energy independence or are on their way to achieving it. This book will prove useful in university education in renewable energy at bachelor and master level, and also for companies and private individuals, who want to start or expand activities in the area of renewable energy.

This book evaluates off-grid solar electrification in Africa by examining how political, economic, institutional, and social forces shape the adoption of off-grid solar technologies, including how issues of energy injustice are manifested at different levels and spaces. The book takes a historical, contemporary, and projective outlook using case studies from pre- and ongoing electrification communities in non-Western countries such as Ghana, Kenya, Rwanda, Senegal, Malawi, Tanzania, and Nigeria. Beyond the diverse nature of these countries in terms of their geographical location in West, East, and Southern Africa, each offers a different experience in terms of colonial history, economic and institutional infrastructure, social and cultural context, and level of adoption of off-grid solar technologies. Notably, the book contributes to the off-grid solar and energy justice scholarship in low-income non-Western contexts. It examines various approaches to energy justice and does so by engaging with Western and non-Western philosophical notions of the concept. It takes into consideration the major principles of Ubuntu philosophy with the adoption of off-grid solar technologies, hence enriching the energy justice framework. Finally, the book interrogates the degree to which the social mission that catalysed the expansion of the off-grid solar sector is being undermined by broader structural dynamics of the capital investment upon which it is reliant. It also argues that the ascendance of off-grid solar electrification in Africa is transformative in that it enables millions of people without access to or facing uncertainties linked to centralised grid energy to have access to basic energy services.

The Solar Electricity Handbook is a practical and straightforward guide to using electric solar panels. Assuming no previous knowledge of solar panels, the book explains how solar panels work, how they can be used and explains the steps you need to take to successfully design and install a solar electric system from scratch using photovoltaic solar panels. Accompanying this book is a solar resource website containing lots of useful information, lists of suppliers and on-line solar energy calculators that will simplify the cost analysis and design processes. Readers can also get in touch with the author directly to ask questions and get further support with their solar projects.
